Nature_of_Operations_and_Basis

Nature of Operations and Basis of Presentation	12 Months Ended
	Dec. 31, 2013
Nature of Operations and Basis of Presentation [Abstract]	'
Nature of Operations and Basis of Presentation	'
	Note 1 - Nature of Operations and Basis of Presentation
		A.	Nature of Operations
	Zion Oil & Gas, Inc., a Delaware corporation (“we”, “our”, “Zion” or the “Company”) is a development stage oil and gas exploration company with a history of more than 13 years of oil & gas exploration in Israel.
	As of December 31, 2013, the Company has no revenues from its oil and gas operations, so  the Company’s activities are considered to be those of a “Development Stage Enterprise”.    Consequently, the Company’s financial statements must be identified as those of a development stage enterprise.    In addition, the statements of operations, stockholders’ equity and cash flows are required to disclose all activity since the Company’s date of inception.    The Company will continue to prepare its financial statements and related disclosures as those of a development stage enterprise until such time that the Company achieves a discovery and has revenues from sales of oil and/or gas.
	Exploration Rights /Exploration Activities
	The Company currently holds three petroleum exploration licenses, all onshore Israel, comprised of the newly granted Megiddo-Jezreel License (covering approximately 98,842 acres), the Asher-Menashe License (covering approximately 78,834 acres), and the Jordan Valley License (covering approximately 55,845 acres of land). Zion’s total license area currently amounts to approximately 233,521 acres.
	(1) In April 2013, Zion submitted to Israel’s Petroleum Commissioner an application seeking a new petroleum exploration license in the Megiddo-Jezreel Valley area, adjacent to and westward of Zion’s existing Jordan Valley License, onshore Israel. The Megiddo-Jezreel Petroleum Exploration License No. 401 was awarded on December 3, 2013 for a three-year primary term through December 2, 2016 with the possibility of additional one-year extensions up to a maximum of seven years.  The Megiddo-Jezreel License covers an area of approximately 98,842 acres of onshore land south and west of Zion’s existing Jordan Valley License.
	(2) The Asher-Menashe License covers an area of approximately 78,834 acres located on the Israeli coastal plain and the Mount Carmel range between Caesarea in the south and Haifa in the north. The Asher-Menashe License, having commenced on June 10, 2007 is scheduled to expire on June 9, 2014.
	(3) The Jordan Valley License covers approximately 55,845 acres, just south of the Sea of Galilee in the Jordan Valley area. The Jordan Valley License, having commenced on April 13, 2011, has an initial three year term which expires on April 12, 2014, which may be extended for additional one-year periods through April 2018 at the option of the Commissioner.
	The Joseph License covered approximately 83,272 acres on the Israeli coastal plain south of the Asher-Menashe License between Caesarea in the north and Netanya in the south. The Joseph License, having commenced on October 11, 2007, expired as of October 10, 2013.
	Megiddo-Jezreel Petroleum License
	Under the terms of this new License, the Company has until July 1, 2015 to identify and submit a drilling prospect, enter into a drilling contract by October 1, 2015, and begin drilling or “spud” a well to a minimum proposed total depth of approximately 4,000 meters (~ 13,125 feet) by December 1, 2015.  These and other geological and geophysical milestones should be achievable before the stated deadlines.
	Asher-Menashe License
	On May 23, 2013, Zion submitted to Israel’s Petroleum Commissioner an application seeking a one-year extension for its Asher-Menashe License to conduct additional in-well testing operations at the Elijah #3 well in hopes of finding commercially productive hydrocarbons. On July 7, 2013, the Commissioner notified us that the Company’s Asher-Menashe License was extended a final time to June 9, 2014. Under the terms of the extension, the Company is required to perform a perforation and stimulation operation at the Elijah #3 well and conduct a production test. If the outcome of the test is negative, the well is to be plugged and abandoned (“P&A”) and within 60 days thereafter, a final report should be submitted and the license returned.
	The Company originally planned to re-enter the Elijah #3 well during October/November 2013, but we were delayed primarily due to problems that Lapidoth, our drilling contractor, experienced while drilling another well with a third party in Israel.  On January 5, 2014, we initiated Elijah #3 re-entry operations and on January 30, 2014, the Lapidoth rig was released.  Although we had hoped to encounter producible hydrocarbons, we did not (other than minimal amounts of gas), and we will now work to finalize all remaining plugging and abandonment procedures for that well.
	See Note 2C and 4 with respect to impairment charges recorded by the Company during the year ended December 31, 2013.
	Jordan Valley License
	The Jordan Valley License is scheduled to expire on April 12, 2014, subject to additional one-year extensions at the option of the Petroleum Commissioner through April 2018. As we reassessed our existing seismic data to prepare to submit our new Megiddo-Jezreel License application, we identified several exploration leads in our existing Jordan Valley License area.
	Zion’s Former Joseph License
	On April 10, 2013, Zion submitted to Israel’s Petroleum Commissioner an application seeking a one-year extension for its Joseph License. On May 12, 2013, the Commissioner notified us that Zion’s Joseph License was extended only for six months, until October 10, 2013. Field operations were conducted from late August to mid-October, 2013 and on November 18, 2013, the Company, in accordance with the license terms, submitted our Final Plugging Report for the Ma’anit Rehoboth #2 and Ma’anit Joseph #3 wells.  The Company has completed the plugging obligations of all wells within the Joseph License area and acknowledges its obligation to complete the abandonment of the wells in accordance with guidance from the Environmental Ministry even though the Joseph License period has technically expired.
	See Note 2C and 4 with respect to impairment charges recorded by the Company during the year ended December 31, 2013.
		B.	Basis of Presentation
	The financial statements for all periods from inception (April 6, 2000) until December 31, 2005 were previously restated to reflect additional expenses related to stock warrants issued to employees and non-employees during the above mentioned period and compensation cost with respect to equity awards provided with new debt issuances and/or debt modification.

Summary_of_Significant_Account

Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2013
Summary of Significant Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	Note 2 - Summary of Significant Accounting Policies
		A.	Financial Statements in United States Dollars
	The currency of the primary economic environment in which the operations of the Company are conducted is the United States dollar (“dollar”).    Therefore, the dollar has been determined to be the Company’s functional currency. Non-dollar transactions and balances have been translated into dollars in accordance with the principles set forth in Accounting Standards Codification (“ASC”) 830 “Foreign Currency Matters”. Transactions in foreign currency (primarily in New Israeli Shekels – “NIS”) are recorded at the exchange rate as of the transaction date. Monetary assets and liabilities denominated in foreign currency are translated on the basis of the representative rate of exchange at the balance sheet date. Non-monetary assets and liabilities denominated in foreign currency are stated at historical exchange rates. All exchange gains and losses from re-measurement of monetary balance sheet items denominated in non-dollar currencies are reflected in the statement of operations as they arise.
		B.	Cash and Cash Equivalents
	The Company maintains cash balances with three banks, of which two banks are located in the United States and one in Israel and money market mutual funds.    For purposes of the statement of cash flows and balance sheet, the Company considers all highly liquid investments with a maturity of three months or less to be cash equivalents. At times, the Company maintains deposits in financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on cash.
		C.	Oil and Gas Properties and Impairment
	The Company follows the full-cost method of accounting for oil and gas properties.  Accordingly, all costs associated with acquisition, exploration and development of oil and gas reserves, including directly related overhead costs, are capitalized.
	All capitalized costs of oil and gas properties, including the estimated future costs to develop proved reserves, are amortized on the unit-of-production method using estimates of proved reserves.    Investments in unproved properties and major development projects are not amortized until proved reserves associated with the projects can be determined or until impairment occurs. If the results of an assessment indicate that the properties are impaired, the amount of the impairment is included in loss from continuing operations before income taxes and the adjusted carrying amount of the unproved properties is amortized on the unit-of-production method.
	The Company’s oil and gas property represents an investment in unproved properties. These costs are excluded from the amortized cost pool until proved reserves are found or until it is determined that the costs are impaired.    All costs excluded are reviewed at least quarterly to determine if impairment has occurred.    The amount of any impairment is charged to expense since a reserve base has not yet been established.    Impairment requiring a charge to expense may be indicated through evaluation of drilling results, relinquishing drilling rights or other information.
	During the year ended December 31, 2013, the Company recorded a non-cash impairment charge of $3,289,000 of its unproved oil and gas properties (see Note 4 and 10) which was comprised of:
		1)	$250,000 incurred in connection with the Elijah #3 re-entry well operations. This decision was based on the fact that no economically producible hydrocarbons were encountered and we will now work to finalize all remaining plugging and abandonment procedures for that well.
		2)	$1,188,000 incurred in connection with the Asher-Menashe License. The Company no longer plans to pursue additional exploration activities in the Asher-Menashe License area.
		3)	$1,851,000 incurred in connection with all remaining capitalized costs of the Joseph License and is due principally to a decision to prioritize available financial resources and focus Zion’s efforts on the Megiddo-Jezreel and Jordan Valley License areas (see Notes 4 and 10).
	Currently, the Company has no economically recoverable reserves and no amortization base. Excluding the impairment charges discussed above in the aggregate amount of $79,258,000, the Company’s unproved oil and gas properties consist of capitalized exploration costs of $2,446,000 and $4,700,000 as of December 31, 2013 and 2012, respectively.
		D.	Property and Equipment
	Property and equipment other than oil and gas property and equipment is recorded at cost and depreciated over its estimated useful lives of three to fourteen years.    Depreciation charged to expense amounted to $86,000, $74,000 and $338,000 for the years ended December 31, 2013, and 2012 and for the period from April 6, 2000 (inception) to December 31, 2013, respectively.
		E.	Assets Held for Severance Benefits
	Assets held for employee severance benefits represent contributions to severance pay funds and  insurance policies that are recorded at their current redemption value.
		F.	Costs Associated with Public and Private Equity Offerings
	Costs associated with each specific private or public equity offering are accumulated until either the closing of the offering or its abandonment.    If the offering is abandoned, the costs are expensed in the period the offering is abandoned.    If the offering is completed and funds are raised, the accumulated costs are recorded as a reduction to additional paid-in capital attributable to the equity offering. Capital issuance costs not attributable to any specific offering are charged to expense as incurred. Costs associated with public and private equity offerings charged to additional paid in capital amounted to $nil, $nil and $4,490,000 for the years ended December 31, 2013, and 2012 and for the period April 6, 2000 (inception) to December 31, 2013, respectively.
		G.	Use of Estimates
	The preparation of the accompanying financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions about future events.    These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses.    Such estimates include the valuation of unproved oil and gas properties, deferred tax assets, asset retirement obligations and legal contingencies.    These estimates and assumptions are based on management’s best estimates and judgment.    Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances.    The Company adjusts such estimates and assumptions when facts and circumstances dictate.    Illiquid credit markets, volatile equity, foreign currency, and energy markets have combined to increase the uncertainty inherent in such estimates and assumptions.    As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.    Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
		H.	Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled (see Note 7). The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statements of operations in the period that includes the enactment date.
	Based on ASC 740-10-25-6, “Income Taxes”, the Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained.    Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized.    Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company accounts for interest and penalties related to unrecognized tax benefits, if and when required, as part of income tax expense in the statement of operations. No liability for unrecognized tax benefits was recognized as of December 31, 2013 and 2012.
		I.	Environmental Costs and Loss Contingencies
	Liabilities for loss contingencies, including environmental remediation costs not within the scope of FASB ASC Subtopic 410-20, Asset Retirement Obligations and Environmental Obligations – Asset Retirement Obligations, arising from claims, assessments, litigation, fines, and penalties and other sources, are recorded when probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated.    Legal costs incurred in connection with loss contingencies are expensed as incurred.    Recoveries of environmental remediation costs from third parties that are probable of realization are separately recorded as assets, and are not offset against the related environmental liability.
	Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study.    Such accruals are adjusted as further information develops or circumstances change.    Costs of expected future expenditures for environmental remediation obligations are not discounted to their present value.
		J.	Asset Retirement Obligation
	Obligations for dismantlement, restoration and removal of facilities and tangible equipment at the end of oil and gas property’s useful life are recorded based on the estimate of the fair value of the liabilities in the period in which the obligation is incurred.    This requires the use of management’s estimates with respect to future abandonment costs, inflation, market risk premiums, useful life and cost of capital.    The estimate of asset retirement obligations does not give consideration to the value the related assets could have to other parties, although it does take into account estimated residual salvage values.    The obligation is recorded if sufficient information about the timing and (or) method of settlement is available to reasonably estimate fair value. (See note 8B)
		K.	Net Loss per Share Data
	Basic and diluted net loss per share of common stock, par value $0.01 per share is presented in conformity with ASC 260-10 “Earnings Per Share”. Diluted net loss per share is the same as basic net loss per share as the inclusion of 3,190,225 and 2,392,000 common stock equivalents in 2013 and 2012 respectively, would be anti-dilutive.
	Due to the new shares of common stock issued in connection with the first rights offering in June 2009, the weighted average shares outstanding was adjusted by a factor of 1.089 which, in turn, adjusted the earnings per share calculations for the bonus element associated with the shares issued as part of such rights offering, as prescribed by ASC 260-10, “Earnings Per Share”.
	Due to the new shares of common stock issued in connection with the second rights offering in December 2009, the weighted average shares outstanding was further adjusted by a factor of 1.037 which, in turn, adjusted the earnings per share calculations for the bonus element associated with the second rights offering shares, as prescribed by ASC 260-10, “Earnings Per Share”.
	Due to the new shares of common stock issued in connection with the fourth rights offering in December 2010, the weighted average shares outstanding was further adjusted by a factor of 1.071 which, in turn, adjusted the earnings per share calculations for the bonus element associated with the fourth rights offering shares, as prescribed by ASC 260-10, “Earnings Per Share”.
	L.        Stock Based Compensation
	The Company follows ASC 718-20-55, “Compensation – Stock Compensation” (“ASC 718-20-55”), which requires measurement of compensation cost for all stock-based awards based upon the fair value on date of grant and recognition of compensation over the service period for awards expected to vest. Under this method, the Company has recognized compensation cost for awards granted beginning January 1, 2006, based on the Black-Scholes option-pricing method.
	The Company accounts for equity instruments issued to non-employees in accordance with the provisions of ASC 505, "Equity", using a fair-value approach.
	As noted, the value of stock option grants is recognized as a compensation expense, on a graded-vesting basis, over the requisite service period of the entire award, net of estimated forfeitures unless vested.
		M.	Fair Value Measurements
	The Company's financial instruments include mainly cash and cash equivalents, other receivables, prepaid expenses, assets held for severance benefits, and accounts payable. The carrying amounts of these financial instruments approximate their fair value.
		N.	Recently Adopted Accounting Pronouncements
	We do not believe that the adoption of recently issued accounting pronouncements in 2013 will have a significant impact on our financial position, results of operations, or cash flow.

Provision for Severance Pay [Abstract]	'
Provision for Severance Pay	'
	Note 3 – Provision for Severance Pay
	Israeli law generally requires payment of severance pay upon dismissal of an employee or upon termination of employment in certain other circumstances. The following plans relate to the employees in Israel:
		A.	The liability in respect of certain of the Company’s employees is discharged in part by participating in a defined contribution pension plan and making regular deposits with recognized pension funds.
			The deposits are based on certain components of the salaries of the said employees.    The custody and management of the amounts so deposited are independent of the Company’s control and accordingly such amounts funded (included in expenses on an accrual basis) and related liabilities are not reflected in the balance sheet.
		B.	The Company’s liability for severance pay for its Israeli employees is calculated pursuant to Israeli severance pay law based on the most recent salary of the employee multiplied by the number of years of employment, as of the balance sheet date.    Employees are entitled to one month’s salary for each year of employment, or a portion thereof.  Certain senior executives are entitled to receive additional severance pay.    The Company’s liability for all of its Israeli employees is partly provided for by monthly deposits in insurance policies and the remainder by an accrual in the financial statements.  The value of these policies is recorded as an asset in the Company’s balance sheet.
		The deposited funds include profits/loss accumulated up to the balance sheet date.    The value of the deposited funds is based on current redemption value of these policies.
		C.	Withdrawals from the funds may be made only upon termination of employment.
		D.	As of December 31, 2013 and 2012, the Company has a provision for severance pay of $177,000 and $199,000, respectively, of which all was long-term. As of December 31, 2013 and 2012, the Company has $144,000 and $114,000, respectively, deposited in funds managed by major Israeli financial institutions which are earmarked to cover severance pay liability. Such deposits are not considered to be “plan assets” and are therefore included in other assets.

	Note 6 - Stockholders’ Equity
		A.	Authorized Shares of Common Stock
	In June 2011, the Company’s shareholders voted to increase the authorized shares of Common Stock from 50 million to 100 million. The increase became effective on June 27, 2011.
		B.	Dividend Reinvestment and Direct Stock Purchase Plan
	On March 27, 2013, the Company filed with the Securities and Exchange Commission (the “SEC”) the prospectus supplement dated as of March 27, 2013 and accompanying base prospectus (collectively, the “Prospectus”) relating to the Company’s Dividend Reinvestment and Direct Stock Purchase Plan (the “DSPP”). The Prospectus forms a part of the Company’s Registration Statement on Form S-3 (File No. 333-174266) which was declared effective by the SEC on May 26, 2011.
	Under the previously announced offering, the Company is offering (a) shares of common stock and (b) through February 28, 2014, units of the Company’s securities with each unit comprised of (i) one share of common stock and (ii) a warrant to purchase an additional share of the Company’s common stock at an exercise price of $2.00 per share for five years. The securities are being offered by the Company in accordance with the terms of the DSPP as described in the Prospectus.
	On August 26, 2013, the Company extended the expiration date for the Unit program under its DSPP to November 29, 2013.
	On November 25, 2013, the Company extended the expiration date for the Unit program under its DSPP to February 28, 2014.
	The extensions were made, in part, to allow interested investors to utilize a new and more convenient electronic enrollment procedure with the TeleCheck Internet Check Acceptance service as a payment method.
	As of December 31, 2013, the Company and its registered agent, Registrar and Transfer Company ("RTC"), had collected approximately $2,478,000 from the DSPP. As a result, the Company issued a total of 1,099,486 shares of its common stock, comprised of 790,975 units (unit comprised of (i) one share of common stock and (ii) a warrant) and 308,511 shares.
		C.	Warrants Terms’ Change
	On June 6, 2012 and October 22, 2012, the Company implemented temporary reductions in the exercise price of all of its then publicly traded warrants, under which these warrants could be exercised, through August 15, 2012 and through their scheduled expiration date of December 31, 2012, respectively, at the reduced warrant exercise price of $1.75. The temporary reduction in exercise prices impacted only the warrants issued to investors in connection with the Company’s equity offerings; consequently no expense was recorded.
	Under the reduced warrant exercise price programs noted above, warrants for a total of 2,255,931 shares were exercised, resulting in cash proceeds to the Company of approximately $3,948,000. As a result of these warrant exercises, the Company issued a total of 2,255,931 shares of its common stock.
		D.	2005 Stock Option Plan
	In 2005, a stock option plan (the “2005 Plan”) was adopted by the Company, pursuant to which 1,000,000 shares of common stock are reserved for issuance to officers, directors, employees and consultants. The Plan is administered by the Board of Directors or one or more committees appointed by the board (the “2005 Plan Administrator”).
	The Plan contemplates the issuance of stock options by the Company both as a private company and as a publicly traded company and is available to residents of the United States, the State of Israel and other jurisdictions as determined by the 2005 Plan Administrator. Awards of stock options under the Plan are made pursuant to an agreement between the Company and each grantee. The agreement will, among other provisions, specify the number of shares subject to the option, intended tax qualifications, the exercise price, any vesting provisions and the term of the stock option grant, all of which are determined on behalf of the Company by the 2005 Plan Administrator. The Plan remains in effect for a term of ten years unless terminated or extended according to its provisions.
	During the year ended December 31, 2013, the Company granted the following options under the 2005 Stock Option Plan to purchase:
		i.	45,000 shares of common stock to executive officers, other staff members and service providers at an exercise price of $0.01. The options vested upon grant and are exercisable through June 28, 2023.  The fair value of the options at the date of grant amounted to $100,425.
		ii.	197,500 shares of common stock to executive officers, other staff members and service providers at an exercise price of $0.01. The options vested upon grant and are exercisable through November 11, 2023.  The fair value of the options at the date of grant amounted to $304,430.
	During the year ended December 31, 2012, the Company did not grant options under the 2005 Plan.
		E.	2011 Equity Incentive Plan and 2011 Non-Employee Directors Stock Option Plan
	In June 2011, the Company’s shareholders authorized the adoption of the Zion Oil & Gas, Inc. 2011 Equity Incentive Plan for employees and consultants (the “2011 Plan”), initially reserving for issuance thereunder 2,000,000 shares of common stock and for non-employee directors initially reserving for issuance thereunder 1,000,000 shares of common stock.
	The 2011 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, bonus stock, awards in lieu of cash obligations, other stock-based awards and performance units. The plan also permits cash payments under certain conditions.
	The compensation committee of the Board of Directors is responsible for determining the type of award, when and to whom awards are granted, the number of shares and the terms of the awards and exercise prices. The options are exercisable for a period not to exceed ten years from the date of grant.
	During the year ended December 31, 2013, the Company granted the following options from the 2011 Plan:
	25,000 shares of common stock were granted to one senior officer at an exercise price of $0.01. The options, granted pursuant to the terms of the officer’ respective employment agreement, vested upon grant and are exercisable through December 31, 2023.  The fair value of the options on their respective dates of grant amounted to $35,024.
	During the year ended December 31, 2012, the Company granted the following options from the 2011 Plan:
		i.	95,000 shares of common stock were granted to certain senior officers at an exercise price of $0.01. The options, granted pursuant to the terms of the officers’ respective employment agreements, vest in four equal quarterly installments from their respective grant dates.  Options for 40,000 shares were exercisable through December 3, 2017, of which options for 10,000 shares were forfeited upon one of the senior officer’s departure from the Company; options for 20,000 shares are exercisable through January 31, 2020; options for 25,000 shares are exercisable through December 21, 2022; and options for 10,000 shares are exercisable through December 4, 2021.  The fair value of the options on their respective dates of grant amounted to $185,196.
		ii.	394,500 shares of common stock to two senior officers, non-management employees and consultants at an exercise price of $1.70. The options vest in equal quarterly installments over eight consecutive quarters, beginning with the quarter ended December 31, 2012. The fair value of the options on their respective dates of grant amounted to $460,700.
	In June 2011, the Company’s shareholders authorized the adoption of the Zion Oil & Gas, Inc. 2011 Non-Employee Directors Stock Option Plan for non-employee directors (the “2011 Directors’ Plan”), initially reserving for issuance thereunder 1,000,000 share of common stock. Under the 2011 Directors’ Plan, only non-qualified options may be issued, and they will be exercisable for a period of six years from the date of grant.
	The Compensation Committee of the Board of Directors is responsible for determining the type of award, when to grant awards, to whom to grant awards, the number of shares and the terms of the awards and exercise prices. The options are exercisable for a period not to exceed six years from the date of grant.
	During the year ended December 31, 2013, the Company granted the following options from the 2011 Directors’ Plan, to purchase:
		i.	25,000 shares of common stock to one non-employee director at an exercise price of $1.73. The options vested upon grant and are exercisable through January 9, 2019.   The fair value of the options at the date of grant amounted to $19,099.

		ii.	160,000 shares of common stock were granted to eight non-employee directors at an exercise price of $1.70. The options vest in equal quarterly installments over eight consecutive quarters, beginning with the quarter ended December 31, 2012. The fair value of the options at their respective dates of grant amounted to $136,607.
		F.	Warrants and Options
	The Company has reserved 3,190,225 shares of common stock as of December 31, 2013 for the exercise of warrants and options to employees and non-employees, of which 2,208,189 are exercisable. These warrants and options could potentially dilute basic earnings per share in future years. The warrants and options exercise prices and expiration dates are as follows:

During the year ended December 31 2012, the expiration dates for 60,000 and 200,000 options previously granted to one senior officer were extended from January 18, 2013 to December 31, 2014 and December 4, 2021 respectively. In connection with the departure of a senior officer, options for 210,000 shares previously granted to such officer and not vested were forfeited. An expense of $279,000 was recorded as an adjustment to the original expense recognized.
The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the options.
The expected life represents the weighted average period of time that options granted are expected to be outstanding. The expected life of the options granted to employees and directors is calculated based on the Simplified Method as allowed under Staff Accounting Bulletin No. 110 ("SAB 110"), giving consideration to the contractual term of the options and their vesting schedules, as the Company does not have sufficient historical exercise data at this time. The expected life of the option granted to non-employees equals their contractual term. In the case of an extension of the option life, the calculation was made on the basis of the extended life.
Prior to 2008, due to the lack of sufficient history of the Company’s stock volatility, the Company estimated its own expected stock volatility based on the historic volatility for other oil exploration companies. Beginning in 2008 and continuing through December 31, 2013, the Company’s stock volatility is based on actual trading of the Company’s stock.
	G.	Compensation Cost for Warrant and Option Issuances
The following table sets forth information about the compensation cost of warrant and option issuances recognized for employees and directors:
					Period from April 6, 2000

Income Taxes	'
	Note 7 – Income Taxes
	The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2013 and 2012 are presented below:
		December 31,			December 31,
		2013			2012
		US$ thousands			US$ thousands
	Deferred tax assets:
	Net operating loss carry forwards		41,230			39,128
	Other		1,577			1,379
	Total gross deferred tax assets		42,807			40,507
	Less – valuation allowance		(41,967	)		(38,891	)
	Net deferred tax assets		840			1,616
	Deferred tax liabilities :
	Property and equipment		(8	)		(18	)
	Unproved oil and gas properties		(832	)		(1,598	)
	Total gross deferred tax liabilities		(840	)		(1,616	)
	Net deferred tax asset		-			-
	In assessing the likelihood of the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets, including net operating losses, is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible and tax carry forwards are utilizable.
	Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. In order to fully realize the deferred tax asset, the Company will need to generate future taxable income of approximately $121,266,000 prior to the expiration of some of the net operating loss carry forwards between 2022 and 2033. Based upon the level of historical taxable losses since the Company’s inception, management believes that the Company will not likely realize the benefits of these deductible differences and tax carry forwards and thus, full valuation allowances have been recorded at December 31, 2013 and 2012.
	At December 31, 2013, the Company has available federal net operating loss carry forwards of approximately $121,266,000 to reduce future U.S. taxable income. These amounts expire from 2022 to 2033.
	Income earned from activities in Israel is subject to regular Israeli tax rates. For Israeli tax purposes, exploration costs on unproved properties are expensed.  Tax losses can be carried forward indefinitely.  At December 31, 2013, the Company has available net operating loss carry forwards of approximately $89,900,000 to reduce future Israeli taxable income.
	Reconciliation between the theoretical tax benefit on pre-tax reported (loss) and the actual income tax expense:
		Year ended			Year ended

	Permanent differences		9			9
	Other differences		1			691
	Change in valuation allowance		3,076			2,800
	Income tax expense		-			-
	The Company has no material unrecognized tax benefit which would favorably affect the effective income tax rate in future periods and do not believe there will be any significant increases or decreases within the next twelve months.  No interest or penalties have been accrued.
	The Company has not received final tax assessments since incorporation. In accordance with the US tax regulations, the U.S. federal income tax returns remain subject to examination for the years beginning in 2010.
	The Israeli branch has not received final tax assessments since incorporation. In accordance with the Israeli tax regulations, tax returns submitted up to and including the 2009 tax year can be regarded as final.

Commitments and Contingencies	12 Months Ended
	Dec. 31, 2013
Commitments and Contingencies [Abstract]	'
Commitments and Contingencies	'
	Note 8 - Commitments and Contingencies
		A.	Litigation
	From time to time, the Company may be subject to routine litigation, claims, or disputes in the ordinary course of business. The Company defends itself vigorously in all such matters. In the opinion of management, no pending or known threatened claims, actions or proceedings against the Company are expected to have a material adverse effect on its financial position, results of operations or cash flows. However, the Company cannot predict with certainty the outcome or effect of any such litigation or investigatory matters or any other pending litigation or claims. There can be no assurance as to the ultimate outcome of any such lawsuits and investigations.
		B.	Asset Retirement
	The Company currently estimates that the costs of plugging and decommissioning of the exploratory wells drilled to date in the Asher-Menashe and Joseph License areas to be approximately $483,000 based on current cost rather than Net Present Value. Liabilities for expenditures are recorded when environmental assessment and/or remediation is probable and the timing and costs can be reasonably estimated.
	Changes in Asset Retirement Obligations were as follows:
			Year ended December 31, 2013			Year ended December 31, 2012
			US$ thousands			US$ thousands
	Asset Retirement Obligations, Beginning Balance			870			870
	Liabilities Settled			(276	)		-
	Revision of Estimate			(111	)		-
	Asset Retirement Obligations, Ending Balance			483			870
	Liabilities of $276,000 were settled related to the Joseph License area.
	Revisions were primarily due to changes in estimated costs for future Plug & Abandonment activities related to the Asher-Menashe and Joseph License areas.
		C.	Environmental Matters
	The Company is engaged in oil and gas exploration and production and may become subject to certain liabilities as they relate to environmental cleanup of well sites or other environmental restoration procedures and other obligations as they relate to the drilling of oil and gas wells or the operation thereof.
	In March 2011, the Ministry of Environmental Protection (Environmental Ministry) issued initial guidelines relating to oil and gas drilling. This is the first time that the Ministry published specific environmental guidelines for oil and gas drilling operations, relating to onshore and offshore Israel. The guidelines are detailed and provide environmental guidance for all aspects of drilling operations, commencing from when an application for a license is filed, and continuing through license award, drilling exploration, production lease, petroleum production and abandonment of the well. The guidelines address details that must be submitted regarding the drill site, surrounding area, the actual drilling operations, the storage and removal of waste and the closing or abandoning of a well. Following meetings between the Ministry and industry representatives in 2011, the Ministry indicated that certain of their initial published guidelines would be revised.
	In January 2012, the Ministry of Energy and Water Resources submitted for review a proposed code titled "Onshore Oil and Gas Exploration and Production-Environment (Health) and Safety Code – Draft". The purpose of the proposed draft code is to regulate and codify onshore environmental and safety matters relating to oil and gas exploration and production in Israel. Under the proposed draft of the code, as a condition to receiving a license for oil and gas exploration, an applicant will have to submit, in writing, an environmental assessment as well as a safety plan that will have to be periodically updated during and after operations. In addition, as a condition to receiving production rights (in the case of a discovery), an applicant will have to submit an environmental impact report as well as a production safety plan.
	In April 2012, the “Environmental Protection Law (Emissions and Transfers to the Environment) Reporting Requirements and Register 2012” became effective. This statute imposes reporting obligations on entities engaged in oil and gas exploration activities in Israel relating to quantities of pollutants emitted into the air, water, land and sea (on an annual basis) and the off-site transfer of waste generated in the facility for treatment. The annual report that is to be furnished does not apply to the Company’s operations until we establish oil and/or gas production.
	In April 2012, the proposed draft regulations relating to petroleum exploratory drilling were adopted in large measure. The new regulations are entitled “Petroleum Regulations (Permission to deviate from the provisions of the Planning and Building Law) 2012” and detail a new permitting process. Among other things, the new regulations require the submission, to the local regulatory and permitting authorities, of a detailed environmental report relating to the proposed drilling site and surroundings. The report is to address, in detail, the environmental implications of the drilling, including hydrological analysis, surface water management, risk assessment, environmental impact, and abandonment and remediation of the drill site, among others. The drilling application must be published and there are specified time frames (approximately 100 days) for any person (including environmental and other interested bodies) to comment on the drilling application.
	In June 2012, the Ministry of Energy and Water Resources (the “Energy Ministry) issued initial guidelines relating to onshore exploratory licensing. Under the guidelines, which have since been adopted, an application will have to meet certain specified conditions and provide detailed information with respect to the requested license area. The applicant must engage, at a minimum, an exploration manager, geologist, geophysicist and engineer with certain minimum years of experience in oil and gas exploration, and at least one of these persons must be a resident of Israel.
	The applicant must also demonstrate the financial resources to support the estimated costs of non-drilling exploratory activities, and at least 50% of the estimated drilling costs, but in any event not less than $5 million. A condition to the issuance of any license is the submission by the licensee of a performance bank guarantee in an amount equal to 10% of the cost of the proposed work program. The performance bank guarantee is required at or prior to the award of the exploration rights.
	In October 2012, the Energy Ministry published proposed guidelines relating to the submission of performance guarantees for new and existing onshore and offshore exploration licenses. Under the proposed guidelines, an applicant for a new onshore exploration license must submit a performance bank guarantee for 10% of the cost of the proposed work program upon the award by the Petroleum Commissioner (the “Commissioner”) of the requested license. An existing onshore exploration license owner will be required to submit a performance bank guarantee equal to 10% of the cost of the balance of the planned work program by the earlier of (a) the application for a license extension, (b) the application for transfer of license rights, or (c) the application for changes to the work program. The face amount of the performance bank guarantee for existing licenses will be based on an estimated budget for the balance of the planned work program that an existing license owner is to submit to the Commissioner, which budget is subject to approval by the Commissioner. In the event that the licensee violates (whether intentionally or not) any of the license terms, then the Commissioner is entitled to demand payment of the bank guarantee, after giving the licensee notice and an opportunity to cure.
	In December 2012, the Energy Ministry published proposed guidelines relating to the submission of bank guarantees for potential drilling-related environmental damages. The guidelines will apply to all petroleum exploration licenses to be granted on or after June 30, 2013 (and possibly extensions of existing licenses). Under the proposed guidelines, prior to receiving the approval of the Commissioner for a proposed drilling program, the licensee must submit a bank guarantee in the amount of $100,000 with respect to a drilling  depth of up to (and including) 1,000 meters, which increases to $250,000 if the drilling depth is more than 1,000 meters. The Commissioner is entitled to demand a bank guarantee in excess of $250,000 if the Commissioner determines that there is a substantial risk of environmental damage. If the licensee causes environmental damage, the Commissioner is entitled to demand payment of the bank guarantee, after giving the licensee notice and an opportunity to respond to the allegation of damages.
	In July 2013, the Environmental Ministry published: “Environmental Guidelines for the preparation of an environmental document supplementary to a license for searching – experimental drilling and land extraction tests.”  This document extensively details the requirements for a supplemental environmental document to an oil and gas exploration plan.
	On December 3, 2013, the State of Israel’s Petroleum Commissioner awarded the Company the Megiddo-Jezreel Petroleum Exploration License No. 401. Subsequently, the Company secured a US $930,000 bank guarantee in accordance with the performance guarantee guidelines.  With these two actions, Zion believes it has met the requirements of the June 2012 onshore exploratory licensing guidelines and the October 2012 performance guarantee guidelines.
	The Company believes that these new regulations will significantly increase the expenditures associated with obtaining new exploration rights and considerably increase the time needed to obtain all of the necessary authorizations and approvals prior to drilling.
		D.	Royalty and Levy Commitments
	The Company is obligated, according to the Petroleum Law, to pay royalties to the Government of Israel on the gross production of oil and gas from the oil and gas properties of the Company located in Israel (excluding those reserves used to operate the wells and related equipment and facilities). The present 12.5% royalty on oil revenues remains unchanged. At December 31, 2013 and 2012, the Company did not have any outstanding obligation with respect to royalty payments, since it is at the “development stage” and, to this date, no proved reserves have been found.
	In March 2011, the Israeli parliament enacted the Petroleum Profits Taxation Law, 2011, which imposes a new levy on oil and gas production. Under the new tax regime, the Israeli Government  repealed the percentage depletion deduction and imposed a levy at an initial rate of 20% will be imposed on profits from oil and gas and will gradually rise to 44.56%, depending on the levy coefficient (the R-Factor). The R-Factor refers to the percentage of the amount invested in the exploration, the development and the establishment of the project, so that the 20% rate will be imposed only after a recovery of 150% of the amount invested (R-Factor of 1.5) and will range linearly up to 44.56 % after a recovery of 230% of the amount invested (R-Factor of 2.3). For purposes of the levy rate calculation, the minimal gas sale price, which will be accepted by the State, is the bi-annual average local price. The present 12.5% royalty imposed on oil revenues remains unchanged.
		E.	Charitable Foundations
	Two charitable foundations were established, one in Israel and one in Switzerland, for the purpose of supporting charitable projects and other charities in Israel, the United States and internationally.  A 3% royalty or equivalent interest in any Israeli oil and gas interests as may now be held or, in the future be acquired, by the Company shall be assigned to each charitable organization (6% interest in the aggregate).  At December 31, 2013 or 2012, the Company did not have any outstanding obligation in respect of the charitable foundations, since it is at the “development stage” and, to this date, no proved reserves have been found.
		F.	Surface Rights of Drilling Operations.
	The surface rights to the drill site from which the Company drilled the Ma’anit-Rehoboth #2 wells and Ma’anit-Joseph #3 well, are held under long-term lease by Kibbutz Ma’anit (the “Kibbutz”) with the Israel Lands Authority.
	The necessary permission to use the drill site for the Ma’anit-Joseph #3 well to conduct petroleum exploration operations was granted to the Company by the Kibbutz in consideration for a fee of approximately $50,000 for the period up to October 10, 2010 and $5,000 for each year thereafter.
	The Israel Lands Authority granted formal consent for the use of the surface with regard to the Ma'anit-Rehoboth #2 well; the expiration date of the consent is March 28, 2013. The Israel Lands Authority granted formal consent for the use of the surface with regard to the Ma'anit-Joseph #3 well; the expiration date of the consent was August 3, 2012; the Company has submitted a request to extend the expiration date
	The Company has now completed the plugging obligations of all wells within the Joseph License and acknowledges its obligation to complete the abandonment of the wells in accordance with guidance from the Environmental Ministry even though the Joseph License period has technically expired.
	The surface rights to the drill site from which the Company drilled the Elijah #3 well are held under long-term lease by Kibbutz Ein Carmel with the Israel Lands Authority. The necessary permission to enter and use the drill site to conduct petroleum operations on the Elijah #3 well was granted to the Company by Kibbutz Ein Carmel through July 20, 2015 in consideration for a one-time fee of approximately $145,000.
	The Israel Lands Authority has granted formal consent for the use of the surface with regard to the Elijah #3 well; the expiration date of the consent was June 21, 2012 and the Company has submitted a request to extend the expiration date.
	Once a specific site or sites have been designated from which we will drill our next deep exploration well(s), the Company will seek the appropriate authority/permission from the local landowner and from the Israel Lands Authority to conduct drilling-related operations.
		G.	Office and Vehicle Leases
	(i) The Company has a lease for 3,600 square feet of corporate office space in Dallas, Texas, which expired on October 31, 2011. On October 11, 2011, the Company and the landlord entered into an amended lease for its current office premises in Dallas, Texas as well as the addition of adjacent space in the building. Pursuant to the lease amendment, the lease term on the existing office space as well as the additional premises was extended to October 31, 2015.
	Rent is paid on a monthly basis and was $6,996 per month for each month from November 1, 2011 through October 31, 2012; thereafter, $7,534 for each month through October 31, 2013; $7,534 for each month through October 31, 2014 and $8,072 for each month through October 31, 2015. Notwithstanding the foregoing, the parties agreed that so long as there was no event of default under the lease amendment, monthly payments of $1,434 through October 31, 2012 and $1,544 thereafter through October 31, 2013 were to be abated.
	(ii) The Company’s field office in Caesarea Israel consists of 5,565 square feet. The sublease term continues through March 31, 2014. Rent is paid on a monthly basis in the base amount of approximately NIS 28,400 per month (approximately $8,100 per month at the exchange rate in effect on the date of this report). The Company is also obligated to pay all cost of living adjustments, as well as its pro-rated portion of all taxes, utilities, and insurance and maintenance payments during the sublease term.
	With the sublease for the company’s field office in Caesarea, Israel expiring in March 2014, on December 19, 2013 the Company signed a new lease agreement with Caesarea Asset Management and Development companies for new premises containing 6,566 square feet. The lease term is five years from February 1, 2014 to January 31, 2019. Rent is to be paid on a monthly basis in the base amount of approximately NIS 37,800 per month (approximately $10,800 per month at the exchange rate in effect on the date of this report and is linked to an increase (but not a decrease) in the CPI. The Company is also obligated to pay all related taxes, utilities, insurance and maintenance payments during the lease term. Pursuant to the lease, twenty-four months from the commencement of the lease term, the Company may terminate the agreement upon three months’ notice provided the Company secures a replacement lessee approved by the lessor at its discretion.
	The Company has an option to renew the lease for another five years, provided it is not in breach of the agreement, where it is required as well to furnish a notice of intent to exercise the option six months prior to termination of lease and furnishes a bank guarantee and insurance confirmation prior to commencement of option period. Under the lease agreement, the Company is authorized to further sublease part of the leased premises to a third party that is pre-approved by the sub-lessor. Rent and its related taxes, utilities, insurance and maintenance expenses for 2013 and 2012 were $256,000 and $238,000, respectively.
	The future minimum lease payments as of December 31, 2013 are as follows:

		H.	Drilling Contract with AME/GYP
	On September 12, 2008, the Company entered into a drilling contract with Aladdin Middle East Ltd. (“AME”) pursuant to which AME shipped into Israel its 2,000 horsepower rig for use in the drilling contemplated by the Company’s business plan. The rig arrived in Israel and cleared customs in April 2009 and was used to drill the Ma’anit-Rehoboth #2 well, the Elijah #3 and the Ma’anit-Joseph #3 well. Drilling operations on the Ma’anit-Joseph #3 well were concluded in July 2011, whereupon the Company released the rig.
	As previously disclosed, AME is part of a group of privately owned affiliated entities. The Company also disclosed that Guyney Yildizi Petrol UretimSondajmut, vc Tic A.S. (“GYP”), an affiliated entity of AME, advised the Company in April 2011 that GYP was the owner of the rig and, following further investigation by the Company, the Company agreed to remit the payments payable under the drilling contract between it and AME directly to GYP. The Company obtained an indemnity from GYP with respect to any damages and costs resulting from such payments to GYP.
	In the context of finalizing amounts owed to GYP under the drilling contract, in April, 2012 GYP advised the Company in writing that approximately $1.5 million remain outstanding under the drilling contract, which amount purportedly included $550,000 in rig demobilization fees.
	In May, 2012, the Company and GYP agreed that the Company would pay GYP $627,000 in full and final settlement of past bills, and such amount was paid on May 15, 2012. However, the matter related to GYP’s demand for $550,000 for rig demobilization was excluded from the settlement. The drilling contract between the Company and AME, which was assumed by GYP, provides that all disputes are to be settled by arbitration in London, United Kingdom.
	On February 25, 2013, GYP advised the Company in writing of GYP's intention to seek arbitration under the drilling contract; however, GYP also indicated its desire to find an amicable solution in lieu of initiating arbitration proceedings and offered a deep discount to resolve the matter.  The Company, which denies it owes anything, offered a nuisance amount to resolve the matter.  The Company's offer has not been accepted by GYP to date and periodic communications continue between it and the Company.
	On October 13, 2013, the Company received a new letter from GYP requesting payment of the $550,000 with no reference to arbitration. By written response on October 29, 2013, the Company respectfully denied any liability on GYP's claim.  On October 31, 2013, the Company received an email from GYP disagreeing with the Company's analysis and threatening arbitration if no satisfactory solution can be found. By written response on November 6, 2013, the Company, citing relevant provisions of the drilling contract, again respectfully denied any liability on GYP's claim.

	I.	Bank Guarantees
As of December 31, 2013, the Company provided bank guarantees to various governmental bodies (approximately $1,143,000) and others (approximately $109,000) in respect of its drilling operation in an aggregate amount of approximately $1,252,000.  The funds backing these guarantees and additional amounts added to support currency fluctuations as required by the bank, are held in interest-bearing accounts and are reported on the company's balance sheet as “restricted cash.

Risks and Uncertainties [Abstract]	'
Risks and Uncertainties	'
	Note 9 – Risks and Uncertainties
	We are directly influenced by the political, economic and military conditions affecting Israel.
	We cannot predict the effect, if any, on our business of renewed hostilities between Israel and its neighbors or any other changes in the political climate in the area. Deterioration of political, economic and security conditions in Israel may adversely affect our operations.
	We are subject to increasing Israeli governmental regulations and environmental requirements that may cause us to incur substantial incremental costs and/or delays in our drilling program.
	Newly enacted onshore licensing and environmental and safety related regulations promulgated by the various energy related ministries in Israel during 2012-2013 have rendered obtaining new explorations licenses more time-consuming and expensive.
	The Company believes that these new environmental regulations will also significantly increase the time, effort, and expenditures associated with obtaining all of the necessary authorizations and approvals prior to drilling any subsequent well.
	Economic risks may adversely affect our operations and/or inhibit our ability to raise additional capital.
	Economically, our operations in Israel may be subject to:
		·	exchange rate fluctuations between the Israeli shekel versus the US Dollar;
		·	royalty and tax increases and other risks arising out of Israeli State sovereignty over the mineral rights in Israel and its taxing authority; and
		·	changes in Israel's economy that could lead to legislation establishing oil and gas price controls.
	Consequently, our operations may be substantially affected by local economic factors beyond our control, any of which could negatively affect our financial performance and prospects.
	Legal risks could negatively affect our market value.
	Legally, our operations in Israel may be subject to:
		·	changes in the Petroleum Law resulting in modification of license and permit rights;
		·	adoption of new legislation relating to the terms and conditions pursuant to which operations in the energy sector may be conducted;
		·	changes in laws and policies affecting operations of foreign-based companies in Israel; and
		·	changes in governmental energy and environmental policies or the personnel administering them.
	Our dependence on the limited contractors, equipment and professional services available in Israel may result in increased costs and possibly material delays in our work schedule.
	The unavailability or high cost of drilling rigs, equipment, supplies, other oil field services and personnel could adversely affect our ability to execute our exploration and development plans on a timely basis and within our budget.
	Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual outcomes may vary materially from those indicated.

Subsequent Events	'
	Note 10 - Subsequent Events
	On January 5, 2014, the Company initiated Elijah #3 re-entry operations and on January 30, 2014, the Lapidoth rig was released.  Although we had hoped to encounter producible hydrocarbons, we did not (other than minimal amounts of gas), and we will now work to finalize all remaining plugging and abandonment procedures for that well.
	On February 6, 2014, the Ministry of Energy and Water Resources issued guidelines for bank guarantees and insurance requirements with respect to oil rights. Under these guidelines, applicants for and existing holders of exploration rights will be required to submit certain bank guarantees and insurance policies that were not previously required.  The Company’s management is studying the new guidelines and evaluating the additional negative impact on the Company.
	As it relates to existing onshore license holders like Zion, the Company must obtain a base guarantee in the New Israeli Shekel equivalent of $500,000, the earlier of:
		·	The date of approval of the application for extension of the license;
		·	The date of submission of an application for transfer of rights;
		·	The date of submission of an application for approval of drilling; or
		·	45 days after the date of publication of the guidelines (late March 2014).
	The Petroleum Commissioner, under exceptional circumstances, may demand a lower or higher guarantee sum.
	Also, as it relates to existing onshore license holders, prior to the start of drilling, an additional bank guarantee in the New Israeli Shekel equivalent of $250,000 will be required.
	Existing onshore license holders must have an insurance policy in place at least 30 days prior to the planned drilling date of a well.  The insurance policy must include that which is usually taken out by international oil or gas exploration or production companies, in accordance with specific requirements set out in the guidelines.
	The Company believes that these and other new regulations will significantly increase the expenditures associated with and serve as a disincentive for operators to engage in oil and gas exploration in Israel. On February 24, 2014, the Company received a request seeking that the Company arrange for three bank guarantees totaling $1.5 Million. The Company disputes that it is obligated to obtain the three bank guarantees even under the new regulations. The Company awaits word on the Israel Oil & Gas Association petition where the association is contemplating a legal challenge in Israel’s Supreme Court and does not plan on providing any of the bank guarantees until the matter is resolved.
	On February 21, 2014, the Company extended the expiration date for the Unit program under its DSPP to June 30, 2014. The extension is made, in part, to allow interested investors to utilize a new and more convenient electronic enrollment procedure with the TeleCheck Internet Check Acceptance service as a payment method.
	On March 4, 2014, the Company received from GYP a request for arbitration. The Company continues to deny GYP's claim and intends to vigorously defend itself.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Summary of Significant Accounting Policies [Abstract]	'
Financial Statements in United States Dollars	'
	A.	Financial Statements in United States Dollars
	The currency of the primary economic environment in which the operations of the Company are conducted is the United States dollar (“dollar”).    Therefore, the dollar has been determined to be the Company’s functional currency. Non-dollar transactions and balances have been translated into dollars in accordance with the principles set forth in Accounting Standards Codification (“ASC”) 830 “Foreign Currency Matters”. Transactions in foreign currency (primarily in New Israeli Shekels – “NIS”) are recorded at the exchange rate as of the transaction date. Monetary assets and liabilities denominated in foreign currency are translated on the basis of the representative rate of exchange at the balance sheet date. Non-monetary assets and liabilities denominated in foreign currency are stated at historical exchange rates. All exchange gains and losses from re-measurement of monetary balance sheet items denominated in non-dollar currencies are reflected in the statement of operations as they arise.
Cash and Cash Equivalents	'
	B.	Cash and Cash Equivalents
	The Company maintains cash balances with three banks, of which two banks are located in the United States and one in Israel and money market mutual funds.    For purposes of the statement of cash flows and balance sheet, the Company considers all highly liquid investments with a maturity of three months or less to be cash equivalents. At times, the Company maintains deposits in financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on cash.
Oil and Gas Properties and Impairment	'
	C.	Oil and Gas Properties and Impairment
	The Company follows the full-cost method of accounting for oil and gas properties.  Accordingly, all costs associated with acquisition, exploration and development of oil and gas reserves, including directly related overhead costs, are capitalized.
	All capitalized costs of oil and gas properties, including the estimated future costs to develop proved reserves, are amortized on the unit-of-production method using estimates of proved reserves.    Investments in unproved properties and major development projects are not amortized until proved reserves associated with the projects can be determined or until impairment occurs. If the results of an assessment indicate that the properties are impaired, the amount of the impairment is included in loss from continuing operations before income taxes and the adjusted carrying amount of the unproved properties is amortized on the unit-of-production method.
	The Company’s oil and gas property represents an investment in unproved properties. These costs are excluded from the amortized cost pool until proved reserves are found or until it is determined that the costs are impaired. All costs excluded are reviewed at least quarterly to determine if impairment has occurred. The amount of any impairment is charged to expense since a reserve base has not yet been established. Impairment requiring a charge to expense may be indicated through evaluation of drilling results, relinquishing drilling rights or other information.
	During the year ended December 31, 2013, the Company recorded a non-cash impairment charge of $3,289,000 of its unproved oil and gas properties (see Note 4 and 10) which was comprised of:
		1)	$250,000 incurred in connection with the Elijah #3 re-entry well operations. This decision was based on the fact that no economically producible hydrocarbons were encountered and we will now work to finalize all remaining plugging and abandonment procedures for that well.
		2)	$1,188,000 incurred in connection with the Asher-Menashe License. The Company no longer plans to pursue additional exploration activities in the Asher-Menashe License area.
		3)	$1,851,000 incurred in connection with all remaining capitalized costs of the Joseph License and is due principally to a decision to prioritize available financial resources and focus Zion’s efforts on the Megiddo-Jezreel and Jordan Valley License areas (see Notes 4 and 10).
	Currently, the Company has no economically recoverable reserves and no amortization base. Excluding the impairment charges discussed above in the aggregate amount of $79,258,000, the Company’s unproved oil and gas properties consist of capitalized exploration costs of $2,446,000 and $4,700,000 as of December 31, 2013 and 2012, respectively.
Property and Equipment	'
	D.	Property and Equipment
	Property and equipment other than oil and gas property and equipment is recorded at cost and depreciated over its estimated useful lives of three to fourteen years.    Depreciation charged to expense amounted to $86,000, $74,000 and $338,000 for the years ended December 31, 2013, and 2012 and for the period from April 6, 2000 (inception) to December 31, 2013, respectively.
Assets Held For Severance Benefits	'
	E.	Assets Held for Severance Benefits
	Assets held for employee severance benefits represent contributions to severance pay funds and  insurance policies that are recorded at their current redemption value.
Costs Associated with Public and Private Equity Offerings	'
	F.	Costs Associated with Public and Private Equity Offerings
	Costs associated with each specific private or public equity offering are accumulated until either the closing of the offering or its abandonment.    If the offering is abandoned, the costs are expensed in the period the offering is abandoned.    If the offering is completed and funds are raised, the accumulated costs are recorded as a reduction to additional paid-in capital attributable to the equity offering. Capital issuance costs not attributable to any specific offering are charged to expense as incurred. Costs associated with public and private equity offerings charged to additional paid in capital amounted to $nil, $nil and $4,490,000 for the years ended December 31, 2013, and 2012 and for the period April 6, 2000 (inception) to December 31, 2013, respectively.
Use of Estimates	'
	G.	Use of Estimates
	The preparation of the accompanying financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions about future events.    These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses.    Such estimates include the valuation of unproved oil and gas properties, deferred tax assets, asset retirement obligations and legal contingencies.    These estimates and assumptions are based on management’s best estimates and judgment.    Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances.    The Company adjusts such estimates and assumptions when facts and circumstances dictate.    Illiquid credit markets, volatile equity, foreign currency, and energy markets have combined to increase the uncertainty inherent in such estimates and assumptions.    As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.    Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Income Taxes	'
	H.	Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled (see Note 7). The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statements of operations in the period that includes the enactment date.
	Based on ASC 740-10-25-6, “Income Taxes”, the Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained.    Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized.    Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company accounts for interest and penalties related to unrecognized tax benefits, if and when required, as part of income tax expense in the statement of operations. No liability for unrecognized tax benefits was recognized as of December 31, 2013 and 2012.
Environmental Costs and Loss Contingencies	'
	I.	Environmental Costs and Loss Contingencies
	Liabilities for loss contingencies, including environmental remediation costs not within the scope of FASB ASC Subtopic 410-20, Asset Retirement Obligations and Environmental Obligations – Asset Retirement Obligations, arising from claims, assessments, litigation, fines, and penalties and other sources, are recorded when probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated.    Legal costs incurred in connection with loss contingencies are expensed as incurred.    Recoveries of environmental remediation costs from third parties that are probable of realization are separately recorded as assets, and are not offset against the related environmental liability.
	Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study.    Such accruals are adjusted as further information develops or circumstances change.    Costs of expected future expenditures for environmental remediation obligations are not discounted to their present value.
Asset Retirement Obligations	'
	J.	Asset Retirement Obligation
	Obligations for dismantlement, restoration and removal of facilities and tangible equipment at the end of oil and gas property’s useful life are recorded based on the estimate of the fair value of the liabilities in the period in which the obligation is incurred.    This requires the use of management’s estimates with respect to future abandonment costs, inflation, market risk premiums, useful life and cost of capital.    The estimate of asset retirement obligations does not give consideration to the value the related assets could have to other parties, although it does take into account estimated residual salvage values.    The obligation is recorded if sufficient information about the timing and (or) method of settlement is available to reasonably estimate fair value. (See note 8B).
Net Loss per Share Data	'
	K.	Net Loss per Share Data
	Basic and diluted net loss per share of common stock, par value $0.01 per share is presented in conformity with ASC 260-10 “Earnings Per Share”. Diluted net loss per share is the same as basic net loss per share as the inclusion of 3,190,225 and 2,392,000 common stock equivalents in 2013 and 2012 respectively, would be anti-dilutive.
	Due to the new shares of common stock issued in connection with the first rights offering in June 2009, the weighted average shares outstanding was adjusted by a factor of 1.089 which, in turn, adjusted the earnings per share calculations for the bonus element associated with the shares issued as part of such rights offering, as prescribed by ASC 260-10, “Earnings Per Share”.
	Due to the new shares of common stock issued in connection with the second rights offering in December 2009, the weighted average shares outstanding was further adjusted by a factor of 1.037 which, in turn, adjusted the earnings per share calculations for the bonus element associated with the second rights offering shares, as prescribed by ASC 260-10, “Earnings Per Share”.
	Due to the new shares of common stock issued in connection with the fourth rights offering in December 2010, the weighted average shares outstanding was further adjusted by a factor of 1.071 which, in turn, adjusted the earnings per share calculations for the bonus element associated with the fourth rights offering shares, as prescribed by ASC 260-10, “Earnings Per Share”.
Stock Based Compensation	'
		Stock Based Compensation
	L.
	The Company follows ASC 718-20-55, “Compensation – Stock Compensation” (“ASC 718-20-55”), which requires measurement of compensation cost for all stock-based awards based upon the fair value on date of grant and recognition of compensation over the service period for awards expected to vest. Under this method, the Company has recognized compensation cost for awards granted beginning January 1, 2006, based on the Black-Scholes option-pricing method.
	The Company accounts for equity instruments issued to non-employees in accordance with the provisions of ASC 505, "Equity", using a fair-value approach.
	As noted, the value of stock option grants is recognized as a compensation expense, on a graded-vesting basis, over the requisite service period of the entire award, net of estimated forfeitures unless vested.
Fair Value Measurements	'
	M.	Fair Value Measurements
	The Company's financial instruments include mainly cash and cash equivalents, other receivables, prepaid expenses, assets held for severance benefits, and accounts payable. The carrying amounts of these financial instruments approximate their fair value.
Recently Adopted Accounting Pronouncements	'
	N.	Recently Adopted Accounting Pronouncements
	We do not believe that the adoption of recently issued accounting pronouncements in 2013 will have a significant impact on our financial position, results of operations, or cash flow.
