Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 - Summary of Significant Accounting Policies *Basis of presentation* These statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") and accounting principles generally accepted in the United States ("GAAP") for interim financial information. They do not include all information and notes required by GAAP for complete financial statements. However, except as disclosed herein, there has been no material change in the information disclosed in the notes to financial statements included in Arête's Annual Report on Form 10-K for the year ended December 31, 2016 as filed with the SEC. In the opinion of management, the accompanying unaudited financial statements contain all adjustments, consisting of normal recurring accruals necessary for a fair presentation of the financial position as of March 31, 2017, and the results of operations, changes in stockholders' equity, and cash flows for the quarters ended March 31, 2017, and 2016. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for a full year. The Company's 2016 Annual Report on Form 10-K includes certain definitions and a summary of significant accounting policies and should be read in conjunction with this Form 10-Q. In connection with the preparation of its unaudited condensed financial statements, the Company evaluated events subsequent to the balance sheet date of March 31, 2017, through the filing date of this report. Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications had no impact on net income (loss) for any period presented. *Going Concern* The accompanying financial statements have been prepared on a going concern basis of accounting, which contemplates continuity of operations, realization of assets and liabilities and commitments in the normal course of business. The accompanying financial statements do not reflect any adjustments that might result if the Company is unable to continue as a going concern. The Company does not generate adequate revenue to satisfy its current operations, has negative cash flows from operations, and incurred significant net operating losses during the quarter ended March 31, 2017, and the years ended December 31, 2016 and 2015, which raise substantial doubt about the Company's ability to continue as a going concern. The ability of the Company to continue as a going concern and appropriateness of using the going concern basis is dependent upon, among other things, additional cash infusion. The Company has historically obtained funds through private placement offerings of equity and debt, as well as, asset sales. There is no assurance that the Company will be able to continue raising the required capital. *Use of estimates* Preparation of the Company's financial statements in accordance with GAAP requires management to make various assumptions, judgments and estimates that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Changes in these assumptions, judgments and estimates will occur as a result of the passage of time and the occurrence of future events and, accordingly, actual results could differ from amounts initially established. The most significant areas requiring the use of assumptions, judgments and estimates relate to the volumes of natural gas and oil reserves used in calculating depreciation, depletion and amortization ("DD&A"), the amount of expected future cash flows used in determining possible impairments of oil and gas properties and the amount of future capital costs used in these calculations. Assumptions, judgments and estimates also are required in determining future asset retirement obligations and impairments of undeveloped properties. *Oil and Gas producing activities* The Company's oil and gas exploration and production activities are accounted for using the successful efforts method. Under this method, all property acquisition costs and costs of exploratory and development wells are capitalized when incurred, pending determination of whether the well has proved reserves. If an exploratory well does not result in proved reserves, the costs of drilling the well are charged to expense and included within cash flows from investing activities in the Statements of Cash Flows. The costs of development wells are capitalized whether productive or nonproductive. Oil and gas lease acquisition costs are also capitalized. Other exploration costs, including certain geological and geophysical expenses and delay rentals for oil and gas leases, are charged to expense as incurred. The sale of a partial interest in a proved property is accounted for as a cost recovery and no gain or loss is recognized as long as this treatment does not significantly affect the unit-of-production DD&A rate. A gain or loss is recognized for all other sales of proved properties and is classified in other operating revenues. Maintenance and repairs are charged to expense, and renewals and betterments are capitalized to the appropriate property and equipment accounts. The Company estimates the expected undiscounted future cash flows of its oil and gas properties and compares such undiscounted future cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, the Company will adjust the carrying amount of the oil and gas properties to fair value. The factors used to determine fair value include, but are not limited to, recent sales prices of comparable properties, the present value of estimated future cash flows, net of estimated operating and development costs using estimates of reserves, future commodity pricing, future production estimates, anticipated capital expenditures and various discount rates commensurate with the risk and current market conditions associated with realizing the expected cash flows projected. Once incurred, a write-down may not be reversed in a later period. For the three month periods ended March 31, 2017 and 2016, the Company recorded impairment expense of $0 and $252,000, respectively, against its oil and gas properties. The provision for DD&A of oil and gas properties is calculated based on proved reserves on a field-by-field basis using the unit-of-production method. Natural gas is converted to barrel equivalents, BOE, at the rate of six Mcf of natural gas to one barrel of oil. Estimated future dismantlement, restoration and abandonment costs, which are net of estimated salvage values, are taken into consideration. Unproved oil and gas properties are periodically assessed for impairment on a project-by-project basis. These impairment assessments are affected by the results of exploration activities, commodity price outlooks, planned future sales or expirations of all or a portion of such projects. If the estimated future net cash flows attributable to such projects are not expected to be sufficient to fully recover the costs invested in each project, the Company will recognize an impairment loss at that time. There was no provision for impairment recorded against its unproved property for the three month periods ended March 31, 2017 and 2016. *Revenue recognition* The Company records revenues from the sale of crude oil, natural gas and natural gas liquids ("NGL") when delivery to the purchaser has occurred and title has transferred. The Company uses the sales method to account for gas imbalances. Under this method, revenue is recorded on the basis of gas actually sold by the Company. In addition, the Company will record revenue for its share of gas sold by other owners that cannot be volumetrically balanced in the future due to insufficient remaining reserves. The Company also reduces revenue for other owners' gas sold by the Company that cannot be volumetrically balanced in the future due to insufficient remaining reserves. The Company's remaining over and under produced gas balancing positions are considered in the Company's proved oil and gas reserves. Gas imbalances at March 31, 2017 and December 31, 2016 were not material. *Earnings per share* Basic net income (loss) per share of common stock is calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during each period. Diluted net income (loss) attributable to common stockholders is calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding and other dilutive securities. The only potentially dilutive securities for the diluted earnings per share calculations consist of Series A2 preferred stock that is convertible into common stock at an exchange price of $2.00 per common share. As of March 31, 2017 and 2016, the convertible preferred stock had an aggregate liquidation preference of $2,767,470 and $2,720,000, respectively and was convertible to 1,384,000 and 1,360,000 shares of common stock, respectively. These shares were excluded from the earnings per share calculation because they would be anti-dilutive. The following table sets forth the calculation of basic and diluted earnings per share: *New accounting pronouncements* Other than as disclosed in the 2016 Form 10-K, there are no other ASUs applicable to the Company that would have a material effect on the Company's financial statements and related disclosures that have been issued but not yet adopted by the Company as of March 31, 2017, and through the filing of this report.

Basis of presentation

These statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") and accounting principles generally accepted in the United States ("GAAP") for interim financial information. They do not include all information and notes required by GAAP for complete financial statements.

In connection with the preparation of its unaudited condensed financial statements, the Company evaluated events subsequent to the balance sheet date of March 31, 2017, through the filing date of this report.

Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications had no impact on net income (loss) for any period presented.

Going Concern

The accompanying financial statements have been prepared on a going concern basis of accounting, which contemplates continuity of operations, realization of assets and liabilities and commitments in the normal course of business. The accompanying financial statements do not reflect any adjustments that might result if the Company is unable to continue as a going concern. The Company does not generate adequate revenue to satisfy its current operations, has negative cash flows from operations, and incurred significant net operating losses during the quarter ended March 31, 2017, and the years ended December 31, 2016 and 2015, which raise substantial doubt about the Company's ability to continue as a going concern. The ability of the Company to continue as a going concern and appropriateness of using the going concern basis is dependent upon, among other things, additional cash infusion. The Company has historically obtained funds through private placement offerings of equity and debt, as well as, asset sales. There is no assurance that the Company will be able to continue raising the required capital.

Use of estimates

Preparation of the Company's financial statements in accordance with GAAP requires management to make various assumptions, judgments and estimates that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Changes in these assumptions, judgments and estimates will occur as a result of the passage of time and the occurrence of future events and, accordingly, actual results could differ from amounts initially established.

The most significant areas requiring the use of assumptions, judgments and estimates relate to the volumes of natural gas and oil reserves used in calculating depreciation, depletion and amortization ("DD&A"), the amount of expected future cash flows used in determining possible impairments of oil and gas properties and the amount of future capital costs used in these calculations. Assumptions, judgments and estimates also are required in determining future asset retirement obligations and impairments of undeveloped properties.

Oil and Gas producing activities

The Company's oil and gas exploration and production activities are accounted for using the successful efforts method.

A gain or loss is recognized for all other sales of proved properties and is classified in other operating revenues. Maintenance and repairs are charged to expense, and renewals and betterments are capitalized to the appropriate property and equipment accounts.

The Company estimates the expected undiscounted future cash flows of its oil and gas properties and compares such undiscounted future cash flows to the carrying amount of the oil and gas properties to determine if the carrying amount is recoverable.

Earnings per share

Basic net income (loss) per share of common stock is calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during each period. Diluted net income (loss) attributable to common stockholders is calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding and other dilutive securities. The only potentially dilutive securities for the diluted earnings per share calculations consist of Series A2 preferred stock that is convertible into common stock at an exchange price of $2.00 per common share.

These shares were excluded from the earnings per share calculation because they would be anti-dilutive.

The following table sets forth the calculation of basic and diluted earnings per share:

New accounting pronouncements

Other than as disclosed in the 2016 Form 10-K, there are no other ASUs applicable to the Company that would have a material effect on the Company's financial statements and related disclosures that have been issued but not yet adopted by the Company as of March 31, 2017, and through the filing of this report.
