	1. Summary of Significant Accounting Policies
	Business. We were incorporated in Nevada on February 4, 2000. In January 2002, we renamed our company Far East Energy Corporation and changed our focus to exploring, developing, producing and selling coalbed methane gas ("CBM"). Throughout this Annual Report on Form 10-K, the terms "Far East Energy," "Far East," "we," "the Company," "us," "our" and "our company" refer to Far East Energy Corporation and its subsidiaries. References to “FEEB” refer to Far East Energy (Bermuda), Ltd., our principal operating subsidiary. References to "China" and "PRC" are references to the People's Republic of China. References to the “MofCom” are references to the Chinese Ministry of Commerce, the principal regulatory authority with oversight responsibility for our production sharing contracts. References to the “MLR” are references to the Chinese Ministry of Land and Resources, the principal regulatory authority for the exploration, development and production of oil and gas resources in China. References to “CUCBM” are references to China United Coalbed Methane Company, Ltd, and references to “CNPC” are references to China National Petroleum Company. Throughout this Annual Report on Form 10-K, we use the term “our Chinese partner company” when referring to CUCBM and CNPC, as applicable.
	The information, as furnished herein, reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. The accompanying consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC.
	Principles of Consolidation. Our consolidated financial statements include the accounts of our wholly-owned subsidiaries after the elimination of all intercompany accounts and transactions.
	Use of Estimates. The preparation of our financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities that exist at the date of the financial statements. Items subject to such estimates and assumptions include: 1) oil and natural gas reserves; 2) cash flow estimates used in impairment tests of long-lived assets; 3) depreciation, depletion and amortization; 4) asset retirement obligations; and 5) income taxes. While we believe our estimates are appropriate, actual results can, and often do, differ from those estimates.
	Cash and Cash Equivalents. We consider short-term investments with little risk of change in value because of changes in interest rates and purchased with an original maturity of three months or less to be cash equivalents.
	Inventory. Inventory consists primarily of tubular goods and drilling equipment used in our operations and is carried at cost with adjustments made from time to time to recognize any reductions in value.
	Oil and Gas Properties. We use the successful efforts method of accounting for our oil and gas properties. Under this method, oil and gas lease acquisition costs and intangible drilling costs associated with exploration efforts that result in the discovery of proved reserves and costs associated with development drilling, whether or not successful, are capitalized when incurred. If proved commercial reserves are not discovered, such drilling costs are expensed. In some circumstances, it may be uncertain whether proved commercial reserves have been found when drilling has been completed. Under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 932, Extractive Activities - Oil and Gas ("ASC 932"), such exploratory well drilling costs may continue to be capitalized if the reserve quantity is sufficient to justify its completion as a producing well and sufficient progress in assessing the reserves and the economic and operating viability of the project is being made. We assess our capitalized exploratory wells pending evaluation each quarter to determine whether costs should remain capitalized or should be charged to earnings. Other exploration costs, including geological and geophysical costs, are expensed as incurred. We recognize gain or loss on the sale of properties on a field basis. Depreciation, depletion and amortization of the cost of proved oil and gas properties is calculated using the unit-of-production method.
	Unproved property costs are capitalized and reviewed periodically for impairment on a field basis, considering factors such as drilling and exploitation plans and lease terms. The estimated fair value of unproved leasehold costs includes the present value of probable reserves discounted at rates commensurate with the risks involved in each classification of reserve. Costs related to impaired prospects are charged to expense. An impairment expense could result if oil and gas prices decline in the future or if downward reserves revisions are recorded, as it may not be economical to develop some of these unproved properties. We also evaluate current drilling results, lease expiration dates, current oil and gas industry conditions, international economic conditions, capital availability, foreign currency exchange rates, political stability in the countries in which the Company has an investment, and available geological and geophysical information. Any impairment assessed is charged to expense.
	Estimates of future dismantlement, restoration, and abandonment costs. The accounting for future development and abandonment costs is determined by FASB ASC Topic 410, Asset Retirement and Environmental Obligations, which requires the fair value of a liability for an asset retirement obligation to be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The liability is accreted each period through charges to depreciation, depletion and amortization. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The accrual is based on estimates of these costs for each of our properties based upon the type of production structure, reservoir characteristics, depth of the reservoir, market demand for equipment, currently available procedures and consultations with construction and engineering consultants. Because these costs typically extend many years into the future, estimating these future costs is difficult and requires management to make estimates and judgments that are subject to future revisions based on numerous factors, including changing technology, the political and regulatory environment, estimates as to the proper discount rate to use and timing of abandonment.
	Convertible Debts and Warrants. We applied FASB ASC Topic 815, Derivatives and Hedging ("ASC 815") and FASB ASC Topic 470, Debt ("ASC 470"), in recording the Exchangeable Note and warrants issued to Dart Energy in conjunction with a transaction between the parties. Derivative financial instruments, as defined in ASC 815, consist of financial instruments or other contracts that contain a notional amount and one or more underlying, require no initial net investment and permit net settlement. Derivative financial instruments may be free-standing or embedded in other financial instruments. Further, derivative financial instruments are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets. Convertible debt, as defined in ASC 470, generally includes an interest rate which is lower than the issuer could establish for nonconvertible debt, an initial conversion price which is greater than the market value of the common stock at the time of issuance, and a conversion price which does not decrease except pursuant to anti-dilution provisions. Also, under ASC 470, the portion of the proceeds from the issuance of the debt which is allocable to the warrant should be accounted for as additional paid-in capital. The allocation should be based on the relative fair values of the two securities at time of issuance.
	Revenue Recognition. We derive revenue primarily from the sale of produced natural gas. Revenues, net of royalties, are recognized when production is sold to a purchaser at a fixed or determinable price, when delivery has occurred and title has transferred, and if the collectability of the revenue is probable. The amount of gas sold may differ from the amount to which the Company is entitled based on its working interest or net revenue interest in the properties. A ready market for natural gas allows us to sell our natural gas shortly after production at the pipeline receipt point at which time title and risk of loss transfers to the buyer. Revenue is recorded when title is transferred based on our deliveries and net revenue interests. Cash received relating to future revenues is deferred and recognized when all revenue recognition criteria are met.
	Significant Customers. All of the Company's production is sold to one customer, Shanxi Province Guoxin Energy Development Group Limited ("SPG"). In the event that this significant customer ceases doing business with us, we believe, but can provide no assurances, that there are potential alternative customers with whom we could establish new relationships and that those relationships would result in the replacement of the lost customer.
	Income Taxes. Deferred income taxes are accounted for under the asset and liability method of accounting for income taxes. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statements carrying amounts and the tax basis of existing assets and liabilities. The effect on deferred taxes of a change in tax rate is recognized in income in the period the change occurs. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.
	Environmental Matters. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations, and do not contribute to current or future revenue generation are expensed. Liabilities are recorded when assessments and/or remediation are deemed probable and the costs can be reasonably estimated.
	Net Loss Per Share. We apply FASB ASC Topic 260, Earnings Per Share ("ASC 260") for the calculation of basic and diluted earnings per share. Basic earnings per share includes no dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution of securities that could share in our earnings.
	Share-based Compensation. We measure the cost of employee services received in exchange for stock options based on the grant date fair value of the awarded options under FASB ASC Topic 718, Compensation - Stock Compensation ("ASC 718"). We determine the fair value of stock option grants using the Black-Scholes option pricing model. We determine the fair value of shares of nonvested stock (also commonly referred to as restricted stock) based on the last quoted price of our stock on the OTC Bulletin Board on the date of the share grant. The fair value determined represents the cost for the award and is recognized over the vesting period during which an employee is required to provide service in exchange for the award. As share-based compensation expense is recognized based on awards ultimately expected to vest, we have reduced the expense for estimated forfeitures based on historical forfeiture rates. Previously recognized compensation costs may be adjusted to reflect the actual forfeiture rate for the entire award at the end of the vesting period. Excess tax benefits, as defined in ASC 718, if any, are recognized as an addition to paid-in capital.
	Comprehensive Loss. Comprehensive loss is defined as changes in financial position of an enterprise excluding stockholder equity transactions. There were no elements of comprehensive loss other than net loss from operations for the years ended December 31, 2013, 2012 and 2011.
	Foreign Currency Transactions. Periodically, we assess the functional currencies of our Chinese subsidiaries to ensure that the appropriate currency is utilized in accordance with the guidance in FASB ASC Topic 830, Foreign Currency Matters ("ASC 830"). During the fourth quarter of 2006, we determined that the functional currency for our Chinese operations was U.S. Dollars, instead of the Chinese Renminbi ("RMB") as previously reported and utilized. Foreign currency transaction gains or losses, which resulted from transactions denominated in the Chinese RMB, were recorded in the Consolidated Statement of Operations.
	Fair Values of Financial Instruments. Our company's financial instruments consist primarily of cash and cash equivalents, payables, and accrued payables. The carrying values of these financial instruments approximate their respective fair values as they are short-term in nature.
	Credit Concentration. As of December 31, 2013, approximately $7.2 million of our cash was held in foreign bank accounts.
	Reclassification. Certain reclassifications have been made to the consolidated balance sheet for the years ended December 31, 2011 and 2012 to be consistent with the 2013 presentation.
	Adoption of New Accounting Pronouncement. There were no recent accounting pronouncements at December 31, 2013 that materially affected our company.

Going Concern and Liquidity [Abstract]	'
Liquidity and Realization of Assets	'
	2. Going Concern and Liquidity
	These consolidated financial statements are presented on the basis that the Company is a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business over a reasonable length of time. The Company generated net losses of $34.0 million for the year ended December 31, 2013, and has accumulated net losses of $183.0 million since inception. In addition, the company has negative working capital, negative cash flows from operating activities and negative net worth. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company’s continuation as a going concern is dependent upon its ability to generate sufficient cash flow to meet its obligations on a timely basis and to obtain additional financing or refinancing as may be required. Management may seek to secure additional capital by exploring potential strategic relationships or transactions involving one or more of our PSCs, such as a joint venture, farmout, merger, acquisition or sale of some or all of our assets, by obtaining additional debt, reserve based, project or equity-related financing. No assurances can be given that the Company will be successful in generating sufficient cash flow or obtaining additional financing or refinancing.  Unless otherwise indicated, amounts provided in these notes to the financial statements pertain to continuing operations.
	All of our reserves are located in Shanxi Province, China. At December 31, 2013, our estimated net proved and net probable reserves were 67.5 billion cubic feet ("Bcf") and 372.4 Bcf of CBM, respectively. At December 31, 2013, the standardized measure of our future net cash flows, discounted at 10 percent per annum, relating to our proved natural gas reserves was $151.8 million. See Supplemental Information to Consolidated Financial Statements.
	On June 12, 2010, China United Coalbed Methane Corporation, Ltd. ("CUCBM"), our Chinese partner for the Shouyang production sharing contract ("PSC"), and SPG executed a gas sales agreement (the "Gas Sales Agreement"), to which we are an express beneficiary, to sell CBM produced in the CBM field governed by the Shouyang PSC. Gas sales under the gas sales agreement with SPG commenced in the first quarter of 2011. As of December 31, 2013 and 2012, gas sales proceeds to be collected were approximately $0.2 million, respectively, and were recorded in Accounts Receivable. We have funded our exploration and development activities primarily through the sale and issuance of common stock, the Notes (as defined below) and the Warrants (as defined below),  proceeds received from the closing of the Facility Agreement (as defined below) and sales of CBM.
	On November 28, 2011, FEEB entered into a Facility Agreement, as borrower, with Standard Chartered Bank ("SCB"), as lender, and the Company, as guarantor (the "Facility Agreement"). The Facility Agreement provides for a $25 million credit facility, the proceeds of which were used for project costs with respect to the Shouyang Area in Shanxi Province, China, as well as for finance costs and for general corporate purposes approved by SCB. The Facility Agreement is fully drawn and no amounts remain for borrowing. See Note 4 - Facility Agreement.
	On January 14, 2013, the Company sold senior secured notes of FEEB (the "Notes") and warrants to purchase common stock of FEEC (the "Warrants") to certain institutional investors for $60,000,000 of gross proceeds in a private placement exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act") pursuant to Section 4(a)(2) thereof and Regulation S thereunder (the "Private Placement"). The Private Placement closed on January 15, 2013.
	On January 15, 2013, FEEC and FEEB entered into the Fifth Amendment to the Facility Agreement, dated November 28, 2011, among FEEC, FEEB and Standard Chartered Bank, to provide for the extension of the maturity date thereof until January 15, 2014. The Fifth Amendment was subject to the repayment of $4.125 million of the outstanding principal amount and the repayment of $0.7 million of capitalized interest under the Facility Agreement. The total amount of outstanding principal and capitalized interest under the Facility Agreement prior to the repayment of such amount was $25.8 million (which included $125,000 borrowed on January 11, 2013). In addition, accrued interest, amendment fees and certain transaction expenses were paid at closing out of the gross proceeds of the Private Placement.
	On December 31, 2013, the Company entered into the Sixth Amendment to the Facility Agreement to extend the maturity date of the Facility Agreement from January 15, 2014 to April 15, 2014.  The Sixth Amendment requires the Company to pay interest under the Facility Agreement on a monthly basis rather than on a quarterly basis.
	On March 31, 2014, the Company entered into the Extension Agreement to the Facility Agreement to extend the maturity date of the Facility Agreement from April 15, 2014 to July 15, 2014.  The Extension Agreement contains certain customary representations, warranties, releases and confirmations.
	Our current work programs satisfied the minimum exploration expenditures for our Shouyang and Yunnan PSCs for 2013. With respect to the PSC governing CBM production activities on the approximately 573,000 acres in the Qinnan block of the Shanxi Province, we have halted activities on the Qinnan Block pending resolution of whether or not its exploration period will be extended as a result of certain force majeure claims.
	Management may seek to secure additional capital by exploring potential strategic relationships or transactions involving one or more of our PSCs, such as a joint venture, farmout, merger, acquisition or sale of some or all of our assets, by obtaining additional debt, reserve based, project or equity-related financing. However, there can be no assurance that we will be successful in entering into any strategic relationship or transaction, securing capital or raising funds through additional debt, reserve based project or equity-related financing. In addition, the terms and conditions of any potential strategic relationship or transaction or of any project or reserve based financing are uncertain, and we cannot predict the timing, structure or other terms and conditions or the consideration that may be paid with respect to any transaction or offering of securities and whether the consideration will meet or exceed our offering price. Under certain circumstances, the structure of a strategic transaction may require the approval of the Chinese authorities, which could delay closing or make the consummation of a transaction more difficult. There can be no assurance that the Chinese authorities will provide the approvals necessary for a transaction or transfer. There can be no guarantee of future capital acquisition, fundraising or exploration success.
	There can be no guarantee of future capital acquisition, fundraising or exploration success or that we will realize the value of our unproved exploratory well costs.

	3. Senior Secured Notes
	On January 14, 2013, FEEC and FEEB entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain purchasers (the “Purchasers”) under which FEEC and FEEB agreed to sell, and the Purchasers agreed to purchase the Notes and Warrants for $60.0 million of gross proceeds in the Private Placement. The Warrants provide the holders the right to purchase up to 56,086,439 shares of FEEC common stock at an exercise price of $0.085 per share.  The Warrants will expire on December 31, 2017. The Private Placement closed on January 15, 2013.
	The Notes are senior secured obligations of FEEB and are fully and unconditionally guaranteed by FEEC. The Notes were sold at an issue price of 100% of par for an aggregate principal amount of $60.0 million. The Notes accrue cash interest at a rate of 13.0% per year, which is paid semi-annually in arrears on June 30 and December 30 of each year, commencing on June 30, 2013. FEEB may, at its option, elect to pay interest “in kind” at a rate of 14.5% per year by issuing additional Notes with the first interest payment required to be paid in kind. The Notes will mature on January 15, 2016.  On July 1, 2013, the Company issued $3,987,501 aggregate principal amount of senior secured notes for the paid in kind interest that was due on June 30, 2013. On December 30, 2013, the Company issued $4,639,095 aggregate principal amount of senior secured notes for the paid in kind interest that was due on December 30, 2013. Consequently, there was no accrued interest at December 31, 2013.  The total amount of interest cost incurred during the year ended December 31, 2013 was $10.2 million, of which $1.3 million has been capitalized.  There was no interest cost or capitalized interest for the years ended December 31, 2012 and 2011.
	The Notes and related guarantees rank equal in right of payment with the Facility Agreement. Except as specifically permitted by the indenture governing the Notes (the “Indenture”), any new indebtedness of FEEC, FEEB or any restricted subsidiary of FEEC will require the consent of SCB and the “Required Noteholders,” which means holders of 75% of aggregate principal amount at maturity of the Notes. The Notes and related guarantees are secured by substantially all of the assets of FEEC and FEEB, other than assets located in the PRC, assets the grant, creation or perfection of any lien on which would require the consent, authorization or approval of, or filing with, any governmental authority in the PRC and certain other excluded assets. Such collateral continues to secure the Facility Agreement with the administration of such collateral subject to a collateral agency and intercreditor agreement between SCB and Wells Fargo Bank, National Association, as indenture trustee of the Notes and as collateral agent.
	If we fail to comply with the covenants in the Indenture governing the Notes or the Facility Agreement or fail to pay the Facility Agreement in full or extend the maturity date of the Facility Agreement by April 15, 2014, it could lead to an event of default and the acceleration of the maturity of all outstanding debt under our Facility Agreement, as well as a cross default and acceleration of maturity under the Indenture governing the Notes.  We have assessed our current liquidity and financial condition, and have determined that the chances that the Company will not be able to pay the Facility Agreement in full or extend the maturity date of the Facility Agreement by April 15, 2014 are not remote. As a result, we have included both the Notes and the Facility Agreement in the current liabilities section of the balance sheet as of December 31, 2013.
	In certain circumstances specified in the Indenture and as summarized below, FEEB may or will be required to redeem or offer to repurchase the Notes at the relevant prices set forth below times the principal amount being redeemed or repurchased:
	Closing Date to February 28, 2014	100%
	March 1, 2014 to December 31, 2014	104%
	January 1, 2015 and thereafter	108%
	plus accrued and unpaid interest thereof, if any, on the Notes to the applicable date of redemption or repurchase, as applicable.
	We applied ASC 470 in the recording of the valuation of the Warrants.  We determined the fair value of the Warrants using the Black Scholes Option Pricing Model (“BSOPM”).
	The significant assumptions used in the valuation were as follows:
		Black Scholes
		Option Pricing Model
	Volatility	70.81%
	Risk free interest rate	0.75%
	Expected dividend yield	-
	Expected term	5 year
	Based on the utilization of the BSOPM valuation technique, the Warrants were valued at approximately $2.5 million at time of issuance.   The amount was recorded as a debt discount to the Notes in the liabilities section and as additional paid-in capital in the equity section of the balance sheet.  The debt discount is accreted as interest expense periodically over the term of the Notes.  We have recorded an accretion amount of $0.7 million from the issuance date to December 31, 2013.
	In connection with the Notes, the Company incurred approximately $3.1 million of financing costs, which included among other items, 1.5 million warrants issued to the placement agent.  These warrants were valued at approximately $68,000 based on the same aforementioned BSOPM valuation technique.    The total financing costs of $3.1 million were allocated between the Notes and the Warrants in proportion to their respective fair values at time of issuance.  The costs related to the Warrants were recorded as an offset to the value of the Warrants in additional paid-in capital.  The costs related to the Notes were capitalized as deferred financing costs and amortized based on the effective interest method over the term of the Notes.  The objective of that method is to arrive at a periodic interest cost which represents a level effective rate over the term of the Notes on its face amount reduced by the unamortized discount and expense at the beginning of the period.  The effective interest rate for the Notes as calculated is 17.8% per annum.  We have recorded an amortization amount of $0.9 million for the period from the issuance date to December 31, 2013.

Facility Agreement	'
	4. Facility Agreement
	On November 28, 2011, FEEB entered into the Facility Agreement, as borrower, with SCB, as lender, and the Company, as guarantor. The Facility Agreement provides for a $25 million credit facility, the proceeds of which were used for project costs with respect to the Shouyang Area in Shanxi Province, China, as well as for finance costs and for general corporate purposes approved by SCB. The Agreement had an initial 9-month term ending August 28, 2012. Loans under the Facility Agreement may be made in such amounts as may be specified from time to time in one or more utilisation requests according to an agreed expenditure schedule. Loans under the Facility Agreement will bear interest at LIBOR plus an applicable margin rate of 9.5% during the initial period and 10.0% thereafter, and mandatory costs, if any, to compensate SCB for certain Hong Kong regulatory compliance costs.  In connection with and as security for the Facility Agreement, FEEB and/or the Company entered into certain other ancillary agreements dated November 28, 2011, including a Share Pledge Agreement, an Account Charge Agreement, an Assignment of Shareholder Loans and a Subordination Agreement (the "Ancillary Agreements").  Under the Ancillary Agreements, the Company pledged its shares in FEEB and granted a security interest in certain intercompany debt to SCB, and FEEB granted a security interest in certain bank accounts to SCB.
	On May 23, 2012, the Company announced that it had entered into an amendment to the Facility Agreement with SCB that, among other things, extended the date upon which the Company was required to provide SCB with evidence of approval by MofCom of the modification agreement to the Shouyang PSC. On July 5, 2012, FEEB was notified of MofCom approval of the modification agreement to the Shouyang PSC. On July 19, 2012, FEEB entered into the First Amendment (the “First Amendment”) to the Facility Agreement, which extended the term of the Facility Agreement by three months, to November 28, 2012.  On November 28, 2012, FEEB entered into the Second Amendment (the “Second Amendment”) to the Facility Agreement, extending the termination date of the Facility Agreement and the due date for payment of all accrued interest to December 19, 2012. On December 18, 2012, FEEB entered into the Third Amendment (the “Third Amendment”) to the Facility Agreement, which extended the termination date of the Facility Agreement and the due date for payment of all accrued interest to January 15, 2013.
	On January 15, 2013, FEEC and FEEB entered into the Fifth Amendment to the Facility Agreement (the "Fifth Amendment") to provide for the extension of the maturity date of the Facility Agreement until January 15, 2014. The Fifth Amendment was subject to the repayment of $4.125 million of the outstanding principal amount and the repayment of $0.7 million of capitalized interest under the Facility Agreement. The total amount of outstanding principal and capitalized interest under the Facility Agreement prior to the repayment of such amount was $25.8 million (which includes $125,000 borrowed on January 11, 2013). In addition, accrued interest, amendment fees and certain transaction expenses were paid at closing out of the gross proceeds of the Private Placement. See Note 3 - Senior Secured Notes for discussion of the Private Placement.
	On December 31, 2013, the Company entered into the Sixth Amendment to the Facility Agreement (the “Sixth Amendment”) to extend the maturity date of the Facility Agreement from January 15, 2014 to April 15, 2014.  The Sixth Amendment requires the Company to pay interest under the Facility Agreement on a monthly basis rather than on a quarterly basis.
	At December 31, 2013 and 2012, the total amount drawn under the Facility Agreement was $21.0 and $25.7 million, respectively. The related accrued interest was $0.5 and $0.1 million for December 31, 2013 and 2012, respectively. The effective interest rate for the Facility Agreement is 13.2% per annum.
	At December 31, 2013 and 2012, total financing costs in connection with the Facility Agreement were approximately $0.6 and $2.6 million, respectively. The costs related to the Facility Agreement were capitalized as deferred financing costs and amortized over the term of the Facility Agreement.  Amortization expense for the year ended December 31, 2013 and 2012 was $0.6 million and $2.4 million, respectively.
	On March 31, 2014, the Company entered into the Extension Agreement to the Facility Agreement (the “Extension Agreement”) to extend the maturity date of the Facility Agreement from April 15, 2014 to July 15, 2014. The Extension Agreement contains certain customary representations, warranties, releases and confirmations.

	5. Transactions with Dart Energy
	In 2009, we entered into a series of transactions related to our Qinnan Block with Dart Energy. In connection with these transactions, one of our wholly owned subsidiaries, FEEB, and Dart Energy entered into a Farmout Agreement (the "Farmout Agreement") under which, subject to certain conditions, FEEB would assign to Dart Energy 75.25% of its rights in the Qinnan PSC in Shanxi Province (the "Assignment"). The Assignment was not carried out and FEEB terminated the Farmout Agreement in November 2011.
	In conjunction with the Farmout Agreement, FEEB issued an Exchangeable Note, $10 million principal amount, to Dart Energy for $10 million in cash and a warrant to Dart Energy for 7,420,000 shares of our common stock, at an exercise price of $1.00 per share ("Warrant"). The Warrant was not exercised and expired in December 2009.
	Of the $10 million principal amount, $2 million was to be set aside to be used exclusively to satisfy FEEB's existing exploration and development commitments in connection with the Qinnan PSC. This restricted portion was fully utilized for exploration expenditures related to the Qinnan PSC by mid-2010.
	The Exchangeable Note had an initial principal amount of $10 million and bore interest at a rate of 8% per annum, which began to accrue on October 16, 2009. In February 2011, Dart Energy exercised its right to exchange a total of $6.8 million in principal amount under the Exchangeable Note for 14,315,789 shares of Common Stock which was sold by Dart Energy shortly after the exchange.
	On September 15, 2011, the Company fulfilled its obligations under the Exchangeable Note by paying in full the remaining $3,200,000 principal balance on the Exchangeable Note plus the $1,226,577 in accrued interest, and the Company elected to terminate the Farmout Agreement on November 11, 2011. The effective interest rate for the Exchangeable Note was 11.64% per annum.

	All of the Company's oil and gas properties are located in the PRC.  For the year ended December 31, 2013, the Company has $90.6 million in proved oil and gas properties and $14.6 million in unproved oil and gas properties.  For the year ended 2012, the Company had $68.7 million in proved oil and gas properties and $3.4 million in unproved oil and gas properties.  The costs associated with our oil and gas properties include the following (in thousands):
		At December 31,

	Total oil and gas properties, net	$	101,334		$	69,929
	Unproved Leasehold Costs.  Unproved leasehold costs are composed of amounts we paid to the PRC's Ministry of Commerce of the People's Republic of China ("MofCom") and CUCBM pursuant to a PSC we entered into in 2002 with CUCBM to acquire the mineral rights in the Enhong and Laochang areas in the Yunnan Province.
	Unproved Oil and Gas Properties.  Unproved oil and gas property costs include only suspended well costs which are direct exploratory well costs pending determination of whether proved reserves have been discovered. Accounting guidance regarding capitalization of suspended well costs is provided by FASB ASC Topic 932.  FASB ASC Topic 932 addresses whether there are circumstances under the successful efforts method of accounting for oil and gas producing activities that would permit the continued capitalization of exploratory well costs beyond one year, other than when additional exploration wells are necessary to justify major capital expenditures and those wells are under way or firmly planned for the near future.  Capitalization of costs should be continued beyond one year in cases where reserves for the project are not yet proven, but the Company demonstrates sufficient continuing progress toward assessing those reserves.  For the capitalized costs at December 31, 2013, our assessment indicated that our current work programs demonstrated our efforts in making sufficient continuing progress toward assessing the reserves in the areas for which the costs were incurred. Therefore, we have continued to capitalize these costs.
	The following table reflects the net changes in capitalized exploratory well costs during 2013, 2012 and 2011 (in thousands):
		2013			2012			2011

		$	-		$	-
	Net operating loss, which can be carried forward for federal income tax purposes, was estimated to be approximately $28.3 million and $24.0 million at December 31, 2013 and 2012, respectively.  The management has determined that it is unlikely that the NOL will be utilized before its expiration beginning in 2016.  Accordingly, a full valuation allowance is provided to comply with the provisions of FASB ASC Topic 740, Income Taxes (“ASC 740”).
	Income taxes for financial reporting purposes differed from the amounts computed by applying the statutory federal income tax rates because Bermuda has no income tax that would apply to FEEB, and because of our recording of the valuation allowance for the losses generated by us. The net increase in the valuation allowance for the year ended December 31, 2013 was $1.7 million.  The net increase in the valuation allowance for the year ended December 31, 2012 was $1.4 million.  The increase for each year was primarily attributable to the net operating losses generated.
	ASC 740 prescribes a minimum recognition threshold and measurement methodology that a tax position taken or expected to be taken in a tax return is required to meet before being recognized in the financial statements. It also provides guidance for derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.  We recognize interest and penalties related to unrecognized tax benefits within the provision for income taxes on continuing operations in our Consolidated Statements of Operations and Comprehensive Loss. There were no unrecognized tax benefits as of the date of adoption.  There are no unrecognized tax benefits that if recognized would affect the tax rate for the year ended December 31, 2013.  There is no interest or penalties recognized as of the date of adoption or for the year ended December 31, 2013.
	The Company files income tax returns in the U.S. Federal jurisdiction and State of Texas.  The 2010 through 2013 tax years generally remain subject to examination by federal and state tax authorities.

	Legal Proceedings. We are periodically named in legal actions arising from normal business activities. We evaluate the merits of these actions and, if we determine that an unfavorable outcome is probable and can be estimated, we will establish the necessary accruals. We do not anticipate any material losses as a result of commitments and contingent liabilities. We are involved in no material legal proceedings.
	Shouyang Production Sharing Contract. We are the operator under the Shouyang PSC to develop the Shouyang Block in Shanxi Province. The term of the Shouyang PSC consists of an exploration period, a development period and a production period. During the exploration period, we hold a 100% participating interest in the properties, and we must bear all exploration costs for discovering and evaluating CBM-bearing areas. We have negotiated and signed multiple amendments with our Chinese partner companies to extend the exploration period under our PSCs. As provided to date, the exploration period of Area A (approximately 15,988 acres or 64.7 square kilometers) of the Shouyang PSC does not expire; while the Exploration Period of Area B (approximately 272,581 acres or 1,103.1 square kilometers) of the Shouyang PSC runs to June 30, 2016.  Pursuant to the provisions of the Fifth Modification Agreement of the Shouyang PSC, the exploration period for Area A will automatically be extended on the original expiration date of June 30, 2015, as we have submitted a report detailing CBM resources to CUCBM that reasonably complies with the Chinese CBM standards.  This report was submitted in connection with the development of an overall development plan and such report was subsequently approved and certifications were received from all requisite levels of the MLR. Additionally we relinquished 121,255 acres (approximately 490.7 square kilometers) known as Area C in June 2013.  We have agreed that we will drill at least 39 additional wells in Area B by June 30, 2016.  The Shouyang PSC expires on July 1, 2032 unless extended.
	We operate approximately 288,569 acres (1,167.8 square kilometers) of the Shouyang Block. There is an approximately 15,988 acre (approximately 64.7 square kilometer) portion of the block that has recently been certified by the Chinese Ministry of Land Resources (the "MLR"), which is a step that is a necessary regulatory requirement to obtain a permanent development license. This portion of the block covers our pilot development wells located in the northern portion of the Shouyang Block (the "1H Pilot Area") and a westward extension thereof. We have a 100% participating interest (subject to a net 3.5% revenue interest held by Phillips) in this portion of the block, which contains all of the wells in the 1H Pilot Area (the area of our current CBM sales) and the planned expansion thereof. With respect to the remaining 272,581 acres (1,103.1 square kilometers), CUCBM maintains the right to elect up to a 30% participating interest upon completion of certain milestones, and we retain the remaining participating interest in the contract area, subject to the 3.5% revenue interest.
	During the exploration period, FEEB must complete at least the minimum work program and seek commercial deposits of CBM that can be developed in commercially paying quantities. In order to shift from the exploration period to the development period, an overall development plan is prepared and submitted for governmental approval for a long-term development license for a particular CBM field. The preparation of an overall development plan to submit as part of the application for a long-term development license will require certification in accordance with MLR standards, as well as technical, commercial, environmental, health and safety plans demonstrating how the CBM field will be developed for the exploitation of CBM located therein. Currently, we and CUCBM are in the process of jointly preparing an overall development plan for approximately 24,661 acres (99.8 square kilometer) located in the northern portion of the Shouyang Block.
	Following expiration of the exploration periods, we may elect to continue the process of trying to convert portions of the Shouyang Block into MLR certified areas in order to transition these areas into the process for a long-term development license. Any acreage that is not at or past the stage of submittal of a technical report that reasonably meets the criteria for MLR certification will be relinquished unless the parties agree otherwise.
	The development period as to any portion of the Shouyang Block will begin after the date of commencement of production of commercial grade quantities of CBM with respect to that area. Any CBM produced and sold prior to the approval of an overall development plan is deemed to occur during the development period, and production is to be distributed in accordance with the parties participating interests in such CBM field. Provided we remain in compliance with the requirements under the Shouyang PSC, the Shouyang PSC allows production to continue on a CBM field until the earlier of the end of the useful life of that area or June 30, 2032, unless extended or otherwise amended.
	Under the PSCs, we have committed to satisfy certain annual minimum exploration expenditure requirements for each PSC. Our minimum exploration expenditure requirement for each block is based on the minimum exploration expenditure requirements of CUCBM established by the MLR, subject to such additional commitments as we deem reasonably necessary and appropriate in light of negotiations to extend the underlying exploration periods of the PSCs. The MLR sets its requirements by applying a minimum expenditure per acre to the total acreage encompassed by each PSC. As a result, the minimum exploration expenditure requirement for 2013 and the minimum exploration expenditure under the Shouyang PSC for each yearly period after 2013 are approximately $2.4 million and $1.9 million, respectively, based on the currency exchange rate between the U.S. Dollar to the Chinese Renminbi ("RMB") as of December 31, 2013. Any portion of the exploration expenditures that exceeds the current year's minimum exploration expenditure requirement cannot be carried forward for the satisfaction of the subsequent year's minimum requirement. Under the Shouyang PSC, we are required to pay certain fees totaling $0.5 million for the year of 2013. These fees include assistance fees, training fees, fees for CBM exploration rights and salaries and benefits. We have completed the minimum work obligations under the Shouyang PSC. We have also met the requirement of drilling 25 wells in the non-MLR certified area by June 30, 2013 and spending at least $11.0 million.  On December 6, 2013, we extended the exploration period of the portion of the Shouyang Block identified as Area B until June 30, 2016, and agreed that we will drill at least 39 additional wells in Area B by June 30, 2016.  The aforementioned amounts are based on the currency exchange rate between the U.S. dollar and the RMB on December 31, 2013.
	Under the Shouyang PSC, we are required to make the following yearly payments to our Chinese partner companies.  As indicated below, certain amounts may change from year to year.

	Qinnan Production Sharing Contract. FEEB is the operator under the Qinnan PSC to develop the Qinnan block in Shanxi Province. CUCBM is in the process of assigning the Qinnan PSC to China National Petroleum Company ("CNPC"). The term of the Qinnan PSC consists of an exploration period, a development period and a production period. During the exploration period, we hold a 100% participating interest in the properties, and we must bear all exploration costs for discovering and evaluating CBM-bearing areas. If any CBM field is discovered, the development costs for that CBM field will be borne by us and CUCBM or CNPC (following the assignment of the Qinnan PSC) in proportion to the respective participating interests. At that time, we will recover that share of the up-front exploration costs allocable to our Chinese partner company through a gradual cost recovery mechanism. The exploration period is divided into three phases called Phase I, Phase II and Phase III. We have completed our Phase I, Phase II and Phase III work program obligations under the Qinnan PSC, and intend to continue pilot development and exploration activities in Phase III until we transition into the development period.
	The exploration period of the Qinnan PSC in Shanxi Province expired on June 30, 2009, and we cannot continue our exploration activities in the Qinnan block without an extension of the exploration period or a new PSC. We are continuing to pursue an extension of the exploration period of the Qinnan PSC, but we cannot be optimistic at this time. We believe that the underlying exploration period should be extended due to events beyond our reasonable control, namely the lengthy transfer of rights taking place from CUCBM to CNPC. At our Chinese partner company's request, we have provided certain operational and financial information to assist them in the decision making process regarding whether to recognize an extension of the exploration period in Qinnan. PetroChina has completed an accounting audit pursuant to the Qinnan PSC of our expenditures for 2007 and 2008. We have also provided to PetroChina, at their request, our work plan for 2010 for Qinnan. In January 2011, we received a formal notice from CNPC that it has purportedly received all Chinese approvals with respect to the transfer of CUCBM's interest to it, and subsequently to its wholly owned affiliate PetroChina. CNPC also requested we execute a modification agreement to confirm PetroChina as our Chinese partner company for the Qinnan PSC. In negotiations with CUCBM and PetroChina related to this request, we have endeavored to negotiate an assignment agreement that would reflect the transfer of interest to CNPC while CNPC and PetroChina would acknowledge delays that were incurred by virtue of us not having, for an extended period of time, an official Chinese partner company that had the capacity or authority under the Qinnan PSC to work with us. Because of the inability to hold a formal joint management committee ("JMC") meeting or to have the effective involvement of our Chinese partner company, we believe that our efforts to continue CBM operations in the Qinnan block have been materially hindered. Technically, the exploration period under the Qinnan PSC expired on June 30, 2009; however, we have maintained the position that the doctrine of force majeure under the Qinnan PSC entitled us to an extension of the exploration period. We continue to discuss this situation with CUCBM and PetroChina, and as recently as January 2012, have submitted a notice of force majeure in accordance with the Qinnan PSC. There can be no assurance that we will be successful in extending the exploration period of the Qinnan PSC or that a new PSC will be granted. Additionally, in connection with obtaining this extension or a new PSC, we may be required to commit to certain expenditures or to modify the terms or respective ownership interests and/or acreage in the applicable PSC.
	Under the Qinnan PSC, we have committed to satisfy certain annual minimum exploration expenditure requirements. As with the Shouyang PSC, our minimum exploration expenditure requirement is based on the minimum exploration expenditure requirements of CNPC established by the MLR. The MLR sets its requirements by applying a minimum expenditure per square kilometer to the total acreage encompassed by each PSC. The annual minimum exploration expenditure requirement under the Qinnan PSC is approximately $3.8 million in the aggregate based on the currency exchange rate between the U.S. Dollar and the RMB as of December 31, 2013. These expenditure requirements are denominated in the RMB and, therefore, are subject to fluctuations in the currency exchange rate between the U.S. Dollar and the RMB. Because the stated expiration date for the exploration period for the Qinnan PSC occurred on June 30, 2009, and we have not yet received an extension, we have halted activities associated with the Qinnan block pending receipt of the requested extension.  Accordingly, we ceased to accrue for the $0.4 million annual fees effective January 1, 2013. We believe the $1.9 million amount accrued is sufficient to cover any obligation related to the fees should the extension be granted.
	Yunnan Production Sharing Contract. On January 25, 2002, we entered into a PSC to develop two areas in Yunnan Province: (1) the Enhong area, which covers approximately 145,198 acres (587.6 square kilometers), and (2) the Laochang area, which covers approximately 119,327 acres (482.9 square kilometers)( the "Yunnan PSC"). FEEB is the operator under the Yunnan PSC. The term of the Yunnan PSC consists of an exploration period, a development period and a production period. The exploration period is divided into two phases, Phase I and Phase II. We have completed Phase I and are operating in Phase II. During the fourth quarter of 2011, we signed a modification agreement to the Yunnan PSC, which was approved by MofCom on June 15, 2012 and extended the exploration period until December 31, 2013, in exchange for allowing CUCBM to proceed at its sole risk with a 100% participating interest in the 145,198 acres (587.6 square kilometers) in the Enhong part of the Yunnan PSC contract area (hence, our interest in the Yunnan PSC now comprises the Laochang area only, and is called the Laochang Block). The exploration period expired on December 31, 2013 and was not amended or extended. Following expiration of the exploration period, we had the right to elect to continue the process of trying to convert portions of the Laochang Area into MLR certified areas in order to transition these areas into the process for a long-term development license and the development period for certain areas. Any acreage that was not at or past the stage of submittal of a technical report to CUCBM that reasonably met the criteria for MLR certification would be relinquished unless the parties otherwise agree.  We have been evaluating this acreage with a minimal exploratory drilling program, and while we believe the acreage to have potential, we have chosen to focus our capital and resources upon the high permeability/high gas content acreage in Shouyang.  The Company and CUCBM have begun discussions that will likely result in the relinquishment of all of the Yunnan acreage covered by the PSC.  The Company expects that any such relinquishment of the PSC will be formalized during the second quarter of 2014.
	Under the Yunnan PSC, we have committed to satisfy certain annual minimum exploration expenditure requirements. Our minimum exploration expenditure requirements for the blocks subject to the Yunnan PSC are based our negotiated agreement to extend the Yunnan PSC exploration period. We are currently obligated to drill a total of eight wells during the entire exploration period, as extended, spending at least $0.8 million (4,850,000 RMB) per year based on the current exchange rate between the U.S. Dollar and the RMB as of December 31, 2013. Under applicable MLR rules for minimum expenditure requirements, the annual minimum exploration expenditure requirement for the Yunnan PSC was approximately $1.8 million per year before the modification but reduced to $0.8 million per year with relinquishment of acreage, based on the currency exchange rate between the U.S. Dollar and the RMB as of December 31, 2013. As we had previously drilled five wells in the Laochang region during Phase II of the Yunnan exploration period, we were only obligated to drill an additional three wells before December 31, 2013 to satisfy the minimum work commitment.  To date, these three wells have not been drilled and we do not at this time intend to drill them.  The Company and CUCBM have begun discussions that will likely result in the relinquishment of all of the Yunnan acreage covered by the PSC.  The Company expects that any such relinquishment of the PSC will be formalized during the second quarter of 2014.
	These requirements are denominated in RMB and, therefore, are subject to fluctuations in the currency exchange rate between the U.S. Dollar and the RMB. The MLR minimum expenditure requirements are a significant factor that influences our exploration work program. Under the Yunnan PSC, we were required to pay certain fees totaling $0.5 million for the year of 2013. These fees include assistance fees, training fees, fees for CBM exploration rights and salaries and benefits. Based on the Yunnan modification agreement, the unfulfilled exploration work commitment will be added to the minimum exploration work commitment for the following year. If we terminate the Yunnan PSC and there exists an unfulfilled balance of the minimum exploration work commitment, we may be required to pay the balance to CUCBM.
	Under the PSCs, we are required to make the following yearly payments to our Chinese partner companies.

Share-Based Compensation	'
	13.   Share-Based Compensation
	We grant shares of nonvested stock of common stock and options to purchase common stock to employees, members of the board of directors and consultants under our shareholder-approved 2005 Stock Incentive Plan (the "2005 Plan").  Options granted under the 2005 Plan must carry an exercise price equal to or above the market value of the stock at the grant date, and a term of no greater than ten years.  The 2005 Plan provides that, unless otherwise agreed, shares of nonvested stock granted under the 2005 Plan must be forfeited upon termination of service.  We issue new shares when options are exercised or shares are granted.  Our option grants under the 2005 Plan to date have generally utilized these terms: exercise price above or equal to average market price on the date of the grant; vesting periods up to four years from date of grant; term of up to ten years; and forfeiture of unexercised vested options after 60-90 days after termination of employment with the Company.  Our shares of nonvested stock granted under the 2005 Plan to date have utilized vesting periods of up to three years.
	Grants prior to the adoption of the 2005 Plan and inducement grants associated with hiring of new employees and appointment of new directors are issued outside of the 2005 Plan.  These grants of options included varying terms, some differing from the above.
	During the first half of 2011, we awarded options to purchase up to 1,785,000 shares of our common stock and 1,669,800 nonvested shares under the 2005 Plan to employees and members of the board of directors; and options to purchase up to 250,000 shares of our common stock and 190,000 nonvested shares outside the 2005 Plan to a new employee and a consultant.
	At the annual meeting of stockholders of the Company held on October 11, 2011, the Company's stockholders approved an amendment to the 2005 Plan which increased the number of shares of common stock issuable from 12,500,000 shares to 22,000,000 shares and increased the number of shares of common stock that may be granted as restricted stock (nonvested shares), restricted stock units or any other stock-based awards from 3,900,000 to 8,000,000 shares.
	During the first six months of 2012, we awarded options to purchase up to 970,000 shares of our common stock and 2,602,500 nonvested shares under the 2005 Plan to employees and members of the board of directors; and options to purchase up to 150,000 shares of our common stock and 105,000 nonvested shares outside the 2005 Plan to a consultant.  We did not award any options to purchase our common stock or any nonvested shares or other full-valued stock-based award during the last half of 2012.
	During the first six months of 2013, we awarded options to purchase up to 3,610,000 shares of our common stock and 1,604,000 nonvested shares under the 2005 Plan to employees and members of the board of directors; and options to purchase up to 325,000 shares of our common stock and 110,000 nonvested shares outside the 2005 Plan to consultants.  As of December 31, 2013, we had 8,612,700 shares available for awards under the 2005 Plan, of which 328,533 shares could be issued as nonvested shares or other full-valued stock-based awards.
	The following table summarizes share based compensation costs recognized under ASC 718 for 2013, 2012 and 2011 (in thousands):

	Tax benefit			-				-				-
	Total share-based compensation costs, net of tax		$	1,140			$	1,052			$	862
	We utilized certain assumptions in determining the fair value of options using the Black-Scholes option pricing model.  Expected volatility is based upon historical volatility.  The risk-free interest rate is based on observed U.S. Treasury rates at date of grant, appropriate for the expected lives of the options.
	Compensation expenses for the stock option grants determined under ASC 718 for 2013 and 2012 were calculated using the Black-Scholes option pricing model with the following assumptions:
			2013				2012
	Dividend yield			0	%			0	%
	Expected volatility			97	%			89	%
	Risk-free interest rate			0.9	%			0.9	%

	Weighted average fair value per share at grant date		$	0.08			$	0.24
	No options were exercised during 2013 or 2012.
	The aggregate intrinsic value for options outstanding and options exercisable at December 31, 2013 is $162,000 and $41,000, respectively.  The weighted average remaining life for the outstanding options is 5.7 years.  A summary of options outstanding as of December 31, 2013 is as follows:

Stockholders' Equity	'
	14.  Stockholders' Equity
	Common Stock.  Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all other directors standing for election. Holders of common stock are entitled to receive proportionately any dividends that may be declared by our board of directors, subject to any preferential rights of outstanding preferred stock. In the event of our liquidation, dissolution or winding up, holders of common stock will be entitled to receive proportionately any of our assets remaining after the payment of liabilities and subject to the prior rights of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights.
	Issuances of Common Stock and Warrants and Debt Issuance.  The table below summarizes placements of our shares of common stock and warrants and debt issuance for the three-year period ended December 31, 2013:
			Shares						Proceeds					Warrants

		-1	In February 2011, Dart Energy exercised its right to exchange a total of $6.8 million in principal amount under the Exchangeable Note (referenced in footnote 2 of this table) for 14,315,789 shares of common stock.  A registered offering was closed in March 2011 for shares of common stock.
		-2	The Company did not issue any common stock or warrants during the year ended December 31, 2012.
		-3	On January 14, 2013, the Company entered into the Securities Purchase Agreement to issue the Notes and Warrants for $60.0 million of gross proceeds in the Private Placement. The Warrants provide the holders the right to purchase up to 56,086,439 shares of FEEC common stock at an exercise price of $0.085 per share.  The Warrants will expire on December 31, 2017.
	Basic and Diluted Shares Outstanding.  Our basic and diluted numbers of shares common stock outstanding in each of the three years presented were the same because we had net losses.  There were (1)13,557,166, 11,148,833, and 10,523,833 options as of December 31, 2013, 2012 and 2011, respectively; and (2)67,161,513, 17,975,074, and 21,994,982 warrants as of December 31, 2013, 2012 and 2011, respectively.
	Resale Restrictions.  On December 31, 2013, we had 346,078,509 shares of common stock outstanding, of which 6,156,161 shares, or 1.8%, were subject to resale restrictions.
	Preferred Stock.  Our board of directors has the authority, without further action by the stockholders, to issue up to 500,000,000 shares of preferred stock in one or more series and to designate the rights, preferences, privileges and restrictions of each series. The issuance of preferred stock could have the effect of restricting dividends on the common stock, diluting the voting power of the common stock, impairing the liquidation rights of the common stock or delaying or preventing our change in control without further action by the stockholders. While we have no present plans to issue any shares of preferred stock, the issuance of preferred stock and this right is currently subject to restrictions under our senior secured notes, we may need to do so in the future in connection with capital raising transactions. In addition, we may issue additional shares of common stock in connection with capital raising activities. The issuance of additional common stock would also have a dilutive impact on our stockholders' ownership interest in our company.
	Warrants.  The following table summarizes warrant transactions for the years ended December 31, 2013, 2012 and 2011.

	Stock Options. In May 2005, our stockholders approved the 2005 Plan, which permits the granting of incentive stock options, stock appreciation rights, restricted stock, restricted stock units and other stock-based awards to employees, consultants and members of the board of directors.  Our shareholders voted in December 2007 to add 4,000,000 shares of common stock to the 2005 Plan.  At the annual general meeting of stockholders of the Company held on July 15, 2009, the Company's stockholders approved an amendment to the 2005 Plan which increased the number of shares of common stock issuable from 7,500,000 shares to 12,500,000 shares and increased the number of shares of common stock that may be granted as nonvested stock, nonvested stock units or any other stock-based awards from 2,400,000 to 3,900,000 shares.
	During the first half of 2011, we awarded options to purchase up to 1,785,000 shares of our common stock and 1,669,800 nonvested shares under the 2005 Plan to employees and members of the board of directors; and options to purchase up to 250,000 shares of our common stock and 190,000 nonvested shares outside the 2005 Plan to a new employee and a consultant.
	At the annual meeting of stockholders of the Company held on October 11, 2011, the Company's stockholders approved an amendment to the 2005 Plan which increased the number of shares of common stock issuable from 12,500,000 shares to 22,000,000 shares and increased the number of shares of common stock that may be granted as restricted stock (nonvested shares), restricted stock units or any other stock-based awards from 3,900,000 to 8,000,000 shares.
	During the first six months of 2012, we awarded options to purchase up to 970,000 shares of our common stock and 2,602,500 nonvested shares under the 2005 Plan to employees and members of the board of directors; and options to purchase up to 150,000 shares of our common stock and 105,000 nonvested shares outside the 2005 Plan to a consultant.  We did not award any options to purchase our common stock or any nonvested shares or other full-valued stock-based award during the last half of 2012.
	During the first six months of 2013, we awarded options to purchase up to 3,610,000 shares of our common stock and 1,604,000 nonvested shares under the 2005 Plan to employees and members of the board of directors; and options to purchase up to 325,000 shares of our common stock and 110,000 nonvested shares outside the 2005 Plan to consultants.
	As of December 31, 2013, we had 8,612,700 shares available for awards under the 2005 Plan, of which 328,533 shares could be issued as nonvested shares or other full-valued stock-based awards.

Summary of Significant Accounting Policies [Abstract]	'
Business	'
	Business. We were incorporated in Nevada on February 4, 2000. In January 2002, we renamed our company Far East Energy Corporation and changed our focus to exploring, developing, producing and selling coalbed methane gas ("CBM"). Throughout this Annual Report on Form 10-K, the terms "Far East Energy," "Far East," "we," "the Company," "us," "our" and "our company" refer to Far East Energy Corporation and its subsidiaries. References to “FEEB” refer to Far East Energy (Bermuda), Ltd., our principal operating subsidiary. References to "China" and "PRC" are references to the People's Republic of China. References to the “MofCom” are references to the Chinese Ministry of Commerce, the principal regulatory authority with oversight responsibility for our production sharing contracts. References to the “MLR” are references to the Chinese Ministry of Land and Resources, the principal regulatory authority for the exploration, development and production of oil and gas resources in China. References to “CUCBM” are references to China United Coalbed Methane Company, Ltd, and references to “CNPC” are references to China National Petroleum Company. Throughout this Annual Report on Form 10-K, we use the term “our Chinese partner company” when referring to CUCBM and CNPC, as applicable.
	The information, as furnished herein, reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. The accompanying consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC.
Principles of Consolidation	'
	Principles of Consolidation. Our consolidated financial statements include the accounts of our wholly-owned subsidiaries after the elimination of all intercompany accounts and transactions.
Use of Estimates	'
	Use of Estimates. The preparation of our financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities that exist at the date of the financial statements. Items subject to such estimates and assumptions include: 1) oil and natural gas reserves; 2) cash flow estimates used in impairment tests of long-lived assets; 3) depreciation, depletion and amortization; 4) asset retirement obligations; and 5) income taxes. While we believe our estimates are appropriate, actual results can, and often do, differ from those estimates.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents. We consider short-term investments with little risk of change in value because of changes in interest rates and purchased with an original maturity of three months or less to be cash equivalents.
Inventory	'
	Inventory. Inventory consists primarily of tubular goods and drilling equipment used in our operations and is carried at cost with adjustments made from time to time to recognize any reductions in value.
Oil and Gas Properties	'
	Oil and Gas Properties. We use the successful efforts method of accounting for our oil and gas properties. Under this method, oil and gas lease acquisition costs and intangible drilling costs associated with exploration efforts that result in the discovery of proved reserves and costs associated with development drilling, whether or not successful, are capitalized when incurred. If proved commercial reserves are not discovered, such drilling costs are expensed. In some circumstances, it may be uncertain whether proved commercial reserves have been found when drilling has been completed. Under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 932, Extractive Activities - Oil and Gas ("ASC 932"), such exploratory well drilling costs may continue to be capitalized if the reserve quantity is sufficient to justify its completion as a producing well and sufficient progress in assessing the reserves and the economic and operating viability of the project is being made. We assess our capitalized exploratory wells pending evaluation each quarter to determine whether costs should remain capitalized or should be charged to earnings. Other exploration costs, including geological and geophysical costs, are expensed as incurred. We recognize gain or loss on the sale of properties on a field basis. Depreciation, depletion and amortization of the cost of proved oil and gas properties is calculated using the unit-of-production method.
	Unproved property costs are capitalized and reviewed periodically for impairment on a field basis, considering factors such as drilling and exploitation plans and lease terms. The estimated fair value of unproved leasehold costs includes the present value of probable reserves discounted at rates commensurate with the risks involved in each classification of reserve. Costs related to impaired prospects are charged to expense. An impairment expense could result if oil and gas prices decline in the future or if downward reserves revisions are recorded, as it may not be economical to develop some of these unproved properties. We also evaluate current drilling results, lease expiration dates, current oil and gas industry conditions, international economic conditions, capital availability, foreign currency exchange rates, political stability in the countries in which the Company has an investment, and available geological and geophysical information. Any impairment assessed is charged to expense.
Estimates of future dismantlement, restoration, and abandonment costs	'
	Estimates of future dismantlement, restoration, and abandonment costs. The accounting for future development and abandonment costs is determined by FASB ASC Topic 410, Asset Retirement and Environmental Obligations, which requires the fair value of a liability for an asset retirement obligation to be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The liability is accreted each period through charges to depreciation, depletion and amortization. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The accrual is based on estimates of these costs for each of our properties based upon the type of production structure, reservoir characteristics, depth of the reservoir, market demand for equipment, currently available procedures and consultations with construction and engineering consultants. Because these costs typically extend many years into the future, estimating these future costs is difficult and requires management to make estimates and judgments that are subject to future revisions based on numerous factors, including changing technology, the political and regulatory environment, estimates as to the proper discount rate to use and timing of abandonment.
Convertible Debts and Warrants	'
	Convertible Debts and Warrants. We applied FASB ASC Topic 815, Derivatives and Hedging ("ASC 815") and FASB ASC Topic 470, Debt ("ASC 470"), in recording the Exchangeable Note and warrants issued to Dart Energy in conjunction with a transaction between the parties. Derivative financial instruments, as defined in ASC 815, consist of financial instruments or other contracts that contain a notional amount and one or more underlying, require no initial net investment and permit net settlement. Derivative financial instruments may be free-standing or embedded in other financial instruments. Further, derivative financial instruments are initially, and subsequently, measured at fair value and recorded as liabilities or, in rare instances, assets. Convertible debt, as defined in ASC 470, generally includes an interest rate which is lower than the issuer could establish for nonconvertible debt, an initial conversion price which is greater than the market value of the common stock at the time of issuance, and a conversion price which does not decrease except pursuant to anti-dilution provisions. Also, under ASC 470, the portion of the proceeds from the issuance of the debt which is allocable to the warrant should be accounted for as additional paid-in capital. The allocation should be based on the relative fair values of the two securities at time of issuance.
Revenue Recognition	'
	Revenue Recognition. We derive revenue primarily from the sale of produced natural gas. Revenues, net of royalties, are recognized when production is sold to a purchaser at a fixed or determinable price, when delivery has occurred and title has transferred, and if the collectability of the revenue is probable. The amount of gas sold may differ from the amount to which the Company is entitled based on its working interest or net revenue interest in the properties. A ready market for natural gas allows us to sell our natural gas shortly after production at the pipeline receipt point at which time title and risk of loss transfers to the buyer. Revenue is recorded when title is transferred based on our deliveries and net revenue interests. Cash received relating to future revenues is deferred and recognized when all revenue recognition criteria are met.
Significant Customers	'
	Significant Customers. All of the Company's production is sold to one customer, Shanxi Province Guoxin Energy Development Group Limited ("SPG"). In the event that this significant customer ceases doing business with us, we believe, but can provide no assurances, that there are potential alternative customers with whom we could establish new relationships and that those relationships would result in the replacement of the lost customer.
Income Taxes	'
	Income Taxes. Deferred income taxes are accounted for under the asset and liability method of accounting for income taxes. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statements carrying amounts and the tax basis of existing assets and liabilities. The effect on deferred taxes of a change in tax rate is recognized in income in the period the change occurs. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.
Environmental Matters	'
	Environmental Matters. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations, and do not contribute to current or future revenue generation are expensed. Liabilities are recorded when assessments and/or remediation are deemed probable and the costs can be reasonably estimated.
Net Loss Per Share	'
	Net Loss Per Share. We apply FASB ASC Topic 260, Earnings Per Share ("ASC 260") for the calculation of basic and diluted earnings per share. Basic earnings per share includes no dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution of securities that could share in our earnings.
Share-based Compensation	'
	Share-based Compensation. We measure the cost of employee services received in exchange for stock options based on the grant date fair value of the awarded options under FASB ASC Topic 718, Compensation - Stock Compensation ("ASC 718"). We determine the fair value of stock option grants using the Black-Scholes option pricing model. We determine the fair value of shares of nonvested stock (also commonly referred to as restricted stock) based on the last quoted price of our stock on the OTC Bulletin Board on the date of the share grant. The fair value determined represents the cost for the award and is recognized over the vesting period during which an employee is required to provide service in exchange for the award. As share-based compensation expense is recognized based on awards ultimately expected to vest, we have reduced the expense for estimated forfeitures based on historical forfeiture rates. Previously recognized compensation costs may be adjusted to reflect the actual forfeiture rate for the entire award at the end of the vesting period. Excess tax benefits, as defined in ASC 718, if any, are recognized as an addition to paid-in capital.
Comprehensive Loss	'
	Comprehensive Loss. Comprehensive loss is defined as changes in financial position of an enterprise excluding stockholder equity transactions. There were no elements of comprehensive loss other than net loss from operations for the years ended December 31, 2013, 2012 and 2011.
Foreign Currency Transactions	'
	Foreign Currency Transactions. Periodically, we assess the functional currencies of our Chinese subsidiaries to ensure that the appropriate currency is utilized in accordance with the guidance in FASB ASC Topic 830, Foreign Currency Matters ("ASC 830"). During the fourth quarter of 2006, we determined that the functional currency for our Chinese operations was U.S. Dollars, instead of the Chinese Renminbi ("RMB") as previously reported and utilized. Foreign currency transaction gains or losses, which resulted from transactions denominated in the Chinese RMB, were recorded in the Consolidated Statement of Operations.
Fair Values of Financial Instruments	'
	Fair Values of Financial Instruments. Our company's financial instruments consist primarily of cash and cash equivalents, payables, and accrued payables. The carrying values of these financial instruments approximate their respective fair values as they are short-term in nature.
Credit Concentration	'
	Credit Concentration. As of December 31, 2013, approximately $7.2 million of our cash was held in foreign bank accounts.
Reclassification	'
	Reclassification. Certain reclassifications have been made to the consolidated balance sheet for the years ended December 31, 2011 and 2012 to be consistent with the 2013 presentation.
Adoption of New Accounting Pronouncement	'
	Adoption of New Accounting Pronouncement. There were no recent accounting pronouncements at December 31, 2013 that materially affected our company.
