Summary of Significant Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	Note 1 – Summary of Significant Accounting Policies
	General Business and Nature of Operations
	ERHC Energy Inc. ("ERHC", the “Company”) is an independent oil and gas company that reports as a development stage enterprise because there are currently no significant revenue generating operations and no revenue has been generated from business activities.  ERHC was formed in 1986, as a Colorado corporation.  The Company’s current focus is to exploit its primary assets, which are rights to working interests in exploration acreage in the Republic of Kenya (“Kenya”), in the Republic of Chad ("Chad"), in the Joint Development Zone (“JDZ”) between the Democratic Republic of Sao Tome and Principe (“DRSTP”), in the Federal Republic of Nigeria (“FRN”) and in the exclusive waters of Sao Tome (the “Exclusive Economic Zone” or “EEZ”).  The Company has formed relationships with upstream oil and gas companies to assist the Company in exploiting its assets in the JDZ as further described in Note 4.  ERHC currently has no other operations.
	Consolidated Financial Statements
	The consolidated financial statements include the accounts of ERHC and its wholly owned subsidiaries, after elimination of all significant inter-company accounts and transactions.
	Use of Estimates
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting period for the years then ended. Actual results could differ significantly from those estimates.
	Concentration of Risks
	ERHC primarily maintains its finances with seven financial institutions. From time to time the amount on deposit in one or all of these institutions may exceed federal insurance limits.  The balances are maintained in demand accounts to minimize risk.
	ERHC’s focus is to exploit its assets which are agreements with the Government of Kenya concerning oil and gas exploration in Kenya, with the Government of Chad concerning oil and gas exploration in Chad, with the DRSTP concerning oil and gas exploration in EEZ and with the JDA concerning oil and gas exploration in the JDZ.  ERHC has formed relationships with Sinopec International Petroleum Exploration and Production Corporation Nigeria (“Sinopec”), and Addax Energy Nigeria Limited (“Addax Ltd.”) to assist ERHC in leveraging its interests in the JDZ. ERHC currently has no other operations.
	Cash Equivalents
	ERHC considers all highly liquid short-term investments with an original maturity of three months or less, when purchased, to be cash equivalents.
	Restricted Certificate of Deposit
	A certificate of deposit was placed with a financial institution to secure a guarantee issued by this financial institution under the terms of Kenya PSC.
	Investment in Oando Energy Resources (OER)
	The Company's investments in common stock and warrants are carried at market value.  Both stocks and warrants are accounted for as available for sale securities, and changes in their fair value are recognized in other comprehensive income (loss).
	Furniture, Fixtures and Equipment
	Furniture, fixtures and equipment are stated at cost and include expenditures for renewals and improvements and capitalized interest. Maintenance and repairs are charged to current operations. When property is retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the respective accounts, and any gain or loss on disposition is included in income. Depreciation is provided principally on the straight-line method over the estimated service lives of the assets. In general, office furniture is depreciated over 7 years, office equipment over 5 years and computer equipment over 3 years.
	Fair Value of Financial Instruments
	Assets and liabilities recorded at fair value in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Level inputs are as follows:
		●	Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
		●	Level 2 Inputs—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.
		●	Level 3 Inputs—Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
	Investments are reported at fair value, determined based on the quoted prices in an active market for identical assets and classified as Level 1 under the ASC 820.
	During the year ended September 30, 2013, the Company’s investment in the common stock and warrants of OER, a Canadian oil and gas company that trades on the Toronto Stock Exchange (TSX) decreased in value by $22,612. This decrease in value is included as a decrease in stockholders' equity in accumulated other comprehensive loss.
	The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values.  Furthermore, while ERHC believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.  In determining fair value, the ERHC generally applies the market approach, which uses prices and other relevant data based on market transactions involving identical or comparable assets and liabilities.  There have been no changes in the methodologies used at September 30, 2013 and 2012.
	See Note 2 “Fair Value of Financial Instruments” for further information.
	Successful Efforts
	ERHC uses the successful efforts method of accounting for oil and gas producing activities.  Under this method, acquisition costs for proved and unproved properties are capitalized when incurred.  Exploration costs, including geological and geophysical costs, the costs of carrying and retaining unproved properties and exploratory dry hole drilling costs, are expensed.  Development costs, including the costs to drill and equip development wells and successful exploratory drilling costs to locate proved reserves are capitalized. Exploratory drilling costs are capitalized when incurred pending the determination of whether a well has found proved reserves.  A determination of whether a well has found proved reserves is made after drilling is completed. The determination is based on a process that relies on interpretations of available geologic, geophysics, and engineering data.  If a well is determined to be successful, the capitalized drilling costs will be reclassified as part of the cost of the well.  If a well is determined to be unsuccessful, the capitalized drilling costs will be charged to expense in the period the determination is made.  If an exploratory well requires a major capital expenditure before production can begin, the cost of drilling the exploratory well will continue to be carried as an asset pending determination of whether proved reserves have been found only as long as: i) the well has found a sufficient quantity of reserves to justify its completion as a producing well if the required capital expenditure is made and ii) drilling of the additional exploratory wells is under way or firmly planned for the near future.  If drilling in the area is not under way or firmly planned, or if the well has not found a commercially producible quantity of reserves, the exploratory well is assumed to be impaired, and its costs are charged to expense.
	In the absence of a determination as to whether the reserves that have been found can be classified as proved, the costs of drilling such an exploratory well is not carried as an asset for more than one year following completion of drilling.  If, after that year has passed, a determination that proved reserves exist cannot be made, the well is assumed to be impaired, and its costs are charged to expense.  Its costs can, however, continue to be capitalized if sufficient quantities of reserves are discovered in the well to justify its completion as a producing well and sufficient progress is made in assessing the reserves and the well’s economic and operating feasibility.
	The impairment of unamortized capital costs is measured at a lease level and is reduced to fair value if it is determined that the sum of expected future net cash flows is less than the net book value. ERHC determines if impairment has occurred through either adverse changes or as a result of the annual review of all fields.
	Development costs of proved oil and gas properties, including estimated dismantlement, restoration and abandonment costs and acquisition costs, are depreciated and depleted on a field basis by the units-of-production method using proved developed and proved reserves, respectively. The costs of unproved oil and gas properties are generally combined and impaired over a period that is based on the average holding period for such properties and the Company’s experience of successful drilling.
	Impairment of Long-lived Assets
	ERHC evaluates the recoverability of long-lived assets when events and circumstances indicate that such assets might be impaired.  ERHC determines impairment by comparing the undiscounted future cash flows estimated to be generated by these assets to their respective carrying amounts.  Impairments are charged to operations in the period to which events and circumstances indicate that such assets might be impaired.  ERHC has evaluated its investments located in Republic Kenya, Republic of Chad and in its DRSTP concession fee in light of its 2003 Option Agreement (see Note 4 and there have been no events or circumstances that would indicate that such assets might be impaired).
	Income Taxes
	Income taxes are accounted for under the assets and liability method.  Under this method, the deferred tax assets and liabilities are estimated based upon the difference between the financial statement and tax bases of assets and liabilities using tax rates in effect for the year in which the Company expects the differences to affect taxable income. The tax consequences of most events recognized in the current year’s financial statements are included in determining income taxes currently payable. However, because tax laws and financial accounting standards differ in their recognition and measurement of assets, liabilities, equity, revenues, expenses, gains and losses, differences arise between the amount of taxable income and pretax financial income for a year and between the tax bases of assets or liabilities and their reported amounts in the financial statements. Because the Company assumes that the reported amounts of assets and liabilities will be recovered and settled, respectively, a difference between the tax basis of an asset or a liability and its reported amount in the balance sheet will result in a taxable or a deductible amount in some future years when the related liabilities are settled or the reported amounts of the assets are recovered, which gives rise to a deferred tax asset. The Company must then assess the likelihood that the deferred tax assets will be recovered from future taxable income and to the extent the Company believes that recovery is not likely, the Company must establish a valuation allowance.
	The Company estimates the provision for income taxes based on income before income taxes for each tax jurisdiction in which the Company has established operations. The Company does not provide incremental U.S. income taxes on un-remitted foreign earnings taxed at rates less than the U.S. tax rates as such earnings are considered permanently invested.
	The Company follows the FASB guidance on accounting for uncertainty in income taxes which provides a financial statement recognition threshold and measurement attribute for a tax position taken or expected to be taken in a tax return. Under this guidance, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The guidance also extends to de-recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures.
	Net Loss Per Share
	Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period.  Diluted loss per share is computed by dividing net loss by the weighted average number of shares outstanding, after giving effect to potentially dilutive common share equivalents outstanding during the period.  Potentially dilutive common share equivalents are not included in the computation of diluted loss per share if they are anti-dilutive.  Diluted loss per common share is the same as basic for all periods presented because the effect of potentially dilutive common shares arising from outstanding stock warrants and options was anti-dilutive. For the years ended September 30, 2013 and 2012, potential dilutive securities had an anti-dilutive effect and were not included in the calculation of diluted net loss per common share.
	Stock-based Compensation
	ERHC recognizes compensation costs resulting from the issuance of stock-based awards to employees and directors over the requisite period based on the fair value of each stock award on the grant date.
	Recent Accounting Pronouncements
	There have been no recently issued accounting pronouncements that have had or are expected to have a material impact on the Company's financial statements.

	Note 3 – Revision to Financial Statements
	ERHC revised its financial statements to report as a development stage company for the year ended September 30, 2006 and subsequent periods.  Accordingly, the statements of operations, stockholders’ equity and cash flows include inception to date amounts.  The consolidated statements of stockholders’ equity of the Company for the years ended from inception (September 5, 1995) through September 30, 1998 were audited by other auditors who are no longer members of the Public Company Accounting Oversight Board ("PCAOB") and whose reports for each of the years ended from inception (September 5, 1995) through September 30, 1998 expressed an unqualified opinion on those statements. Because the other auditors were no longer members of the PCAOB, the inception to date amounts shown in the accompanying statements of operations and statement of cash flows are considered unaudited.

	b.	spend at least $10,250,000 over the first two years on a minimum work program, and
	In September, 2013, the Company entered into a farm-out agreement with an international oil and gas company (the"Kenya farm-out partner").  Under the terms of this agreement, and contingent upon the consent of the Government of Kenya and other conditions, the Company will assign and transfer 55% of its participating interest in Kenya Block 11A to the Kenya farm-out partner.  In exchange for the transferred rights, Kenya farm-out partner will carry Company's the Company's proportionate share of obligations and financial costs under the terms outlined in the farm-out agreement.  The agreement is contingent upon the Kenyan Government's approval.
	Republic of Chad Concession Fees and Other Financial Commitments
	On June 30, 2011, ERHC entered into a production sharing contract ("PSC") with Chad for certain onshore hydrocarbon exploration and development.  In September 2013, the Ministry of Energy and Petroleum of Chad approved ERHC's application to voluntarily relinquish two of the three Blocks covered by the PSC.  The voluntary relinquishment proportionately reduces ERHC's total signature-bonus obligations of $6,000,000 under the initial PSC to $2,000,000.
	Following is an analysis of the costs paid or incurred at September 30, 2013 and 2012:
			2013				2012
	Signature bonus		$	2,000,000			$		6,000,000
	Advisers' and ancillary costs related to the PSC			528,576					320,000
	Legal fees and costs for the drafting and negotiation of the PSC, as provided in PSC			480,000					480,000
	Meeting fees and other costs		$	3,008,576			$		6,800,600
	ERHC is also committed under the PSC to:
	a.	spend at least $15,000,000 over the first five years on a minimum work program and at least an additional $1,000,000 over a further period of up to three years
	b.	incur surface fees of $16,360 per calendar year during the first validity period starting on July 12, 2012, and lasting for up to eight years.  Surface fees for subsequent periods will depend on the exploration progress as well as on the acreage retained by ERHC.
	Sao Tome Concession
	In April 2003, the Company and the DRSTP entered into an Option Agreement (the "2003 Option Agreement") in which the Company relinquished certain financial interests in the JDZ in exchange for exploration rights in the JDZ.  The Company additionally entered into an administration agreement with the Nigeria-Sao Tome and Principe JDA.  The administration agreement is the formal agreement by the JDA that it will fully implement ERHC's preferential rights to working interests in the JDZ acreage as set forth in the 2003 Option Agreement and describes certain procedures regarding the exercising of these rights.  However, ERHC retained under a previous agreement the following rights to participate in exploration and production activities in the EEZ subject to certain restrictions:  (a) the right to receive 100% working interest signature free bonus of two blocks of ERHC's choice and (b) the option to acquire up to a 15% paid working interest in up to two additional blocks of ERHC's choice in the EEZ.  The Company would be responsible for its proportionate share of exploration and exploitation costs in the EEZ blocks.
	The following represents ERHC's current rights in the JDZ and EEZ blocks:
	Block		ERHC Original		ERHC Joint Bid	Participating		Current ERHC		Remaining Cost Allocated to Blocks

	EEZ 11		100.00%		-	-		100.00%			567,900
	The Original Participating Interest is the interest granted pursuant to the Option Agreement, dated April 2, 2003, between DRSTP and ERHC (the "2003 Option Agreement").
	Under the terms each of the Participation Agreements Sinopec and Addax agreed to pay all of ERHC's future costs for petroleum operations ("the carried costs") in respect of ERHC's retained interests in JDZ blocks 2,3 and 4. Additionally, Sinopec and Addax are entitled to 100% of ERHC's allocation of cost oil plus up to 50% of ERHC's allocation of profit oil from the retained interests on individual blocks until Sinopec and Addax Sub recover 100% of ERHC's carried costs.
	The remaining $2,839,500 of cost related to the DRSTP concession, as shown on the Company's balance sheet at September 30, 2013 and 2012, relate to blocks 5, 6 and 9 of the JDZ, and the Company's EEZ blocks on which Production Sharing Contracts are yet to be signed.  As of September 30, 2013, blocks 5 and 6 are in arbitration (see Note 8).

	In preparing the Company’s consolidated financial statements, the Company assesses the likelihood that its deferred tax assets will be realized from future taxable income.  The Company establishes a valuation allowance if it determines that it is more likely than not that some portion of the deferred tax assets will not be realized. Changes in the valuation allowance, when recorded, would be included in its consolidated statements of operations as a provision for (benefit from) income taxes.  The Company exercise significant judgment in determining its provisions for income taxes, its deferred tax assets and liabilities and its future taxable income for purposes of assessing its ability to utilize any future tax benefit from its deferred tax assets. During 2013, the Company assessed the need for a valuation allowance against its deferred tax assets.  The deferred tax asset valuation allowance was $10,792,808 as of September 30, 2013. The valuation allowance relates primarily to the net operating losses and various expense deductions for which a tax benefit is currently unavailable.
	At September 30, 2013, the Company has Federal net operating loss carry forward of approximately $23,977,627.  The federal loss carry forward expires on various dates through 2032.
	Uncertainty in Tax Positions
	On October 1, 2007, the Company adopted the guidance related to accounting for uncertainty in income taxes, which provides a financial statement recognition threshold and measurement attribute for a tax position taken or expected to be taken in a tax return.  Under ASC 740, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position.  The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.  ASC 740 also provides guidance on de-recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures.
	The Company is subject to taxation in the United States and various foreign jurisdictions. The Company’s tax years for 2007 through 2013 are subject to examination by the tax authorities. The Company is currently under examination by the Internal Revenue Service for the 2006 tax year. Management has determined that the Company has no uncertain tax positions requiring recognition under ASC 740 as of September 30, 2013 and 2012.

	Common Stock
	During the years ended September 30, 2013 and 2012, ERHC issued 10,560,910, shares of common stock for payment of director and employee services, to third parties for payment of fees and for issuances under private placements as follows:
	Year ended September 30, 2013 issuances
		(i)	420,000 shares were granted to directors for 2013 service, but unissued at September 30, 2013, with related compensation expense of $25,200 recognized based on the market price of the stock on the grant date. Additional expenses of $24,813 relating to previously unrecognized share-based compensation (grants from prior years) was recorded during the year ended September 30, 2013.
		(ii)	On December 17, 2012 the Company implemented a rights offering under the terms of which each shareholder was entitled to non-transferable subscription rights to purchase shares of common stock at a subscription price of $0.075 per share. Under the rights offering, the Company offered up to 246,486,285 shares of its common stock (or roughly 33% of outstanding shares at the date of the offering). On December 27, 2012 the Company issued one subscription right to current shareholders for every three shares of common stock held at the December 17, 2012 record date. The Rights Offering was closed on March 15, 2013 and resulted to net proceeds to the Company of $1,540,178 from the exercise of approximately 22,000,000 subscription rights (including certain oversubscription privileges). A total of 24,970,406 shares were issued from the Rights Offering.
	Year ended September 30, 2012 issuances
		(i)	525,000 shares were granted to directors for 2012 service, but unissued at September 30, 2012, with related compensation expense of $73,500 recognized based on the market price of the stock on the grant date. Additional expenses of $26,943 relating to previously unrecognized share-based compensation (grants from prior years) was recorded during the year ended September 30, 2012.
	Stock Options
	On January 6, 2012, the Board of Directors granted a total of 4,750,000 stock options to officers and board of directors members of the Company under the Company’s 2004 Stock Option Plan. The options vest over two years, are exercisable for a period of 2 years and have a $0.20 strike price. However, the options are only exercisable if the Company’s share price reaches $0.75 per share and remains consistently at or above that level for a period of one month.  They have a grant-date fair value of $63,711 or $0.013 per share based on and independent valuation of the options using a lattice model and the following weighted average assumptions:
	Risk free interest rate			0.25	%
	Dividend yield			0	%
	Annual volatility			105.97	%
	Exit/Attrition rates			2	%
	Target exercise multiple			2.14	%
	During the years ended September 30, 2013 and 2012, the Company recognized compensation expense of $24,813 and $23,892 related to the options grant as described above.  During the second quarter of fiscal 2013, 600,000 options with a total amortized value of $4,023 were forfeited upon resignation of one of the directors of the Company.  As of September 30, 2013, none of the options are exercisable, the weighted average remaining term is 0.25 year and the intrinsic value is zero. Unamortized compensation cost related to these options amounted to $6,958 which is expected to be recognized over a remaining period of 0.25 year.

	Legal Proceedings
	JDZ Blocks 5 and 6
	Lawsuit
	On November 3, 2008, the Company filed a suit at the Federal High Court in Nigeria to prevent any tampering with its rights in JDZ Blocks 5 and 6 pending the outcome of arbitration over the said rights.
	The Company was awarded a 15 percent working interest in each of the Blocks in a 2004/5 bid/licensing round conducted by the JDA following the exercise by ERHC of preferential rights in the Blocks as guaranteed by contract and treaty.  The dispute is entirely contractual. The JDA and the Government of STP contend that certain correspondence issued by a previous CEO/President of the Company in 2006 amount to a relinquishment of the Company’s rights in Blocks 5 and 6 under the Company’s contracts with STP which provide for the rights.  The Company contends that no such relinquishment has occurred and has sought recourse to arbitration accordingly.
	Arbitration
	In November 2008, the Company dispatched notices of arbitration for service on the JDA and the Governments of Nigeria and Săo Tomé & Príncipe to commence arbitration in London. ERHC wants the London Court of International Arbitration to clarify that ERHC's interests in JDZ Blocks 5 and 6 remain intact.
	Suspension of Proceedings on the Lawsuit and Arbitration
	Proceedings on the suit and the arbitration are currently suspended while the Company pursues amicable settlement with the Governments of Nigeria and Săo Tomé Príncipe.
	From time to time, ERHC may be subject to routine litigation, claims, or disputes in the ordinary course of business.  ERHC intends to defend these matters vigorously; the Company cannot predict with certainty, however, the outcome or effect of any of the litigation or investigatory matters specifically described above or any other pending litigation or claims.  There can be no assurance as to the ultimate outcome of these lawsuits and investigations.
	Operating Lease
	ERHC leases office space at 5444 Westheimer Road, Houston, Texas.  The lease for office space expires July 31, 2017.  The lease calls for monthly base rent payments of $9,825 for approximately 5,200 square feet.  During the years ended September 30, 2013 and 2012, ERHC incurred lease expenses of $123,561 and $117,895, respectively.  The future remaining annual minimum lease payments under this lease are as follows:
	Year Ended
	September 30,	Amount
	2014		126,416
	2015		129,027
	2016		131,638
	2017		110,968
		$	498,049
	The Company also leases various office spaces located outside of the United States with terms ranging from 6 months to 6 years.   Total rent expense under these leases for the years ended September 30, 2013 and 2012 amount to $181,133 and $41,048, respectively.

Summary of Significant Accounting Policies [Abstract]	'
Consolidated Financial Statements	'
	Consolidated Financial Statements
	The consolidated financial statements include the accounts of ERHC and its wholly owned subsidiaries, after elimination of all significant inter-company accounts and transactions.
Use of Estimates	'
	Use of Estimates
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting period for the years then ended. Actual results could differ significantly from those estimates.
Concentration of Risks	'
	Concentration of Risks
	ERHC primarily maintains its finances with seven financial institutions. From time to time the amount on deposit in one or all of these institutions may exceed federal insurance limits.  The balances are maintained in demand accounts to minimize risk.
	ERHC’s focus is to exploit its assets which are agreements with the Government of Kenya concerning oil and gas exploration in Kenya, with the Government of Chad concerning oil and gas exploration in Chad, with the DRSTP concerning oil and gas exploration in EEZ and with the JDA concerning oil and gas exploration in the JDZ.  ERHC has formed relationships with Sinopec International Petroleum Exploration and Production Corporation Nigeria (“Sinopec”), and Addax Energy Nigeria Limited (“Addax Ltd.”) to assist ERHC in leveraging its interests in the JDZ. ERHC currently has no other operations.
Cash Equivalents	'
	Cash Equivalents
	ERHC considers all highly liquid short-term investments with an original maturity of three months or less, when purchased, to be cash equivalents.
Furniture, Fixtures and Equipments	'
	Furniture, Fixtures and Equipment
	Furniture, fixtures and equipment are stated at cost and include expenditures for renewals and improvements and capitalized interest. Maintenance and repairs are charged to current operations. When property is retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the respective accounts, and any gain or loss on disposition is included in income. Depreciation is provided principally on the straight-line method over the estimated service lives of the assets. In general, office furniture is depreciated over 7 years, office equipment over 5 years and computer equipment over 3 years.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Assets and liabilities recorded at fair value in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Level inputs are as follows:
		●	Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
		●	Level 2 Inputs—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.
		●	Level 3 Inputs—Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
	Investments are reported at fair value, determined based on the quoted prices in an active market for identical assets and classified as Level 1 under the ASC 820.
	During the year ended September 30, 2013, the Company’s investment in the common stock and warrants of OER, a Canadian oil and gas company that trades on the Toronto Stock Exchange (TSX) decreased in value by $22,612. This decrease in value is included as a decrease in stockholders' equity in accumulated other comprehensive loss.
	The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values.  Furthermore, while ERHC believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.  In determining fair value, the ERHC generally applies the market approach, which uses prices and other relevant data based on market transactions involving identical or comparable assets and liabilities.  There have been no changes in the methodologies used at September 30, 2013 and 2012.
Successful Efforts	'
	Successful Efforts
	ERHC uses the successful efforts method of accounting for oil and gas producing activities.  Under this method, acquisition costs for proved and unproved properties are capitalized when incurred.  Exploration costs, including geological and geophysical costs, the costs of carrying and retaining unproved properties and exploratory dry hole drilling costs, are expensed.  Development costs, including the costs to drill and equip development wells and successful exploratory drilling costs to locate proved reserves are capitalized. Exploratory drilling costs are capitalized when incurred pending the determination of whether a well has found proved reserves.  A determination of whether a well has found proved reserves is made after drilling is completed. The determination is based on a process that relies on interpretations of available geologic, geophysics, and engineering data.  If a well is determined to be successful, the capitalized drilling costs will be reclassified as part of the cost of the well.  If a well is determined to be unsuccessful, the capitalized drilling costs will be charged to expense in the period the determination is made.  If an exploratory well requires a major capital expenditure before production can begin, the cost of drilling the exploratory well will continue to be carried as an asset pending determination of whether proved reserves have been found only as long as: i) the well has found a sufficient quantity of reserves to justify its completion as a producing well if the required capital expenditure is made and ii) drilling of the additional exploratory wells is under way or firmly planned for the near future.  If drilling in the area is not under way or firmly planned, or if the well has not found a commercially producible quantity of reserves, the exploratory well is assumed to be impaired, and its costs are charged to expense.
	In the absence of a determination as to whether the reserves that have been found can be classified as proved, the costs of drilling such an exploratory well is not carried as an asset for more than one year following completion of drilling.  If, after that year has passed, a determination that proved reserves exist cannot be made, the well is assumed to be impaired, and its costs are charged to expense.  Its costs can, however, continue to be capitalized if sufficient quantities of reserves are discovered in the well to justify its completion as a producing well and sufficient progress is made in assessing the reserves and the well’s economic and operating feasibility.
	The impairment of unamortized capital costs is measured at a lease level and is reduced to fair value if it is determined that the sum of expected future net cash flows is less than the net book value. ERHC determines if impairment has occurred through either adverse changes or as a result of the annual review of all fields.
	Development costs of proved oil and gas properties, including estimated dismantlement, restoration and abandonment costs and acquisition costs, are depreciated and depleted on a field basis by the units-of-production method using proved developed and proved reserves, respectively. The costs of unproved oil and gas properties are generally combined and impaired over a period that is based on the average holding period for such properties and the Company’s experience of successful drilling.
Impairment of Long-lived Assets	'
	Impairment of Long-lived Assets
	ERHC evaluates the recoverability of long-lived assets when events and circumstances indicate that such assets might be impaired.  ERHC determines impairment by comparing the undiscounted future cash flows estimated to be generated by these assets to their respective carrying amounts.  Impairments are charged to operations in the period to which events and circumstances indicate that such assets might be impaired.  ERHC has evaluated its investments located in Republic Kenya, Republic of Chad and in its DRSTP concession fee in light of its 2003 Option Agreement (see Note 4 and there have been no events or circumstances that would indicate that such assets might be impaired).
Income Taxes	'
	Income Taxes
	Income taxes are accounted for under the assets and liability method.  Under this method, the deferred tax assets and liabilities are estimated based upon the difference between the financial statement and tax bases of assets and liabilities using tax rates in effect for the year in which the Company expects the differences to affect taxable income. The tax consequences of most events recognized in the current year’s financial statements are included in determining income taxes currently payable. However, because tax laws and financial accounting standards differ in their recognition and measurement of assets, liabilities, equity, revenues, expenses, gains and losses, differences arise between the amount of taxable income and pretax financial income for a year and between the tax bases of assets or liabilities and their reported amounts in the financial statements. Because the Company assumes that the reported amounts of assets and liabilities will be recovered and settled, respectively, a difference between the tax basis of an asset or a liability and its reported amount in the balance sheet will result in a taxable or a deductible amount in some future years when the related liabilities are settled or the reported amounts of the assets are recovered, which gives rise to a deferred tax asset. The Company must then assess the likelihood that the deferred tax assets will be recovered from future taxable income and to the extent the Company believes that recovery is not likely, the Company must establish a valuation allowance.
	The Company estimates the provision for income taxes based on income before income taxes for each tax jurisdiction in which the Company has established operations. The Company does not provide incremental U.S. income taxes on un-remitted foreign earnings taxed at rates less than the U.S. tax rates as such earnings are considered permanently invested.
	The Company follows the FASB guidance on accounting for uncertainty in income taxes which provides a financial statement recognition threshold and measurement attribute for a tax position taken or expected to be taken in a tax return. Under this guidance, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The guidance also extends to de-recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures.
Net Loss Per Share	'
	Net Loss Per Share
	Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period.  Diluted loss per share is computed by dividing net loss by the weighted average number of shares outstanding, after giving effect to potentially dilutive common share equivalents outstanding during the period.  Potentially dilutive common share equivalents are not included in the computation of diluted loss per share if they are anti-dilutive.  Diluted loss per common share is the same as basic for all periods presented because the effect of potentially dilutive common shares arising from outstanding stock warrants and options was anti-dilutive. For the years ended September 30, 2013 and 2012, potential dilutive securities had an anti-dilutive effect and were not included in the calculation of diluted net loss per common share.
