Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company is subject to U.S. federal income tax and the Texas margin tax. Altus Midstream LP is a partnership for federal income tax purposes and passes through its taxable income to its partners, the Company, Apache, and the Preferred Unit holders. Thus, Altus Midstream LP does not record a federal income tax provision. Altus Midstream LP is subject to the Texas margin tax and as such, records a state income tax provision. On March 27, 2020, the President signed into law the Coronavirus Aid, Relief and Economic Security Act (CARES Act) in response to the COVID-19 pandemic. Under the CARES Act, 100 percent of net operating losses arising in tax years beginning after December 31, 2017 and before January 1, 2021 may be carried back to each of the five preceding tax years of such loss. In the first quarter of 2020, the Company recorded a current income tax benefit of $0.7 million associated with a net operating loss carryback claim. During the three months ended March 31, 2021, the Company’s effective income tax rate was primarily impacted by a decrease in valuation allowance. During the three months ended March 31, 2020, the Company’s effective income tax rate was primarily impacted by the net operating loss carryback claim under the CARES Act and an increase in valuation allowance. The Company accounts for income taxes in accordance with ASC Topic 740, “Income Taxes,” which prescribes a minimum recognition threshold a tax position must meet before being recognized in the financial statements. Each quarter, the Company assesses the recognition amount and, as a result, may increase (expense) or reduce (benefit) the amount of interest and penalties. Interest and penalties are recorded as a component of income tax expense. The contributor of Altus Midstream’s operating assets, Apache, is currently under IRS audit for the 2014-2017 tax years as part of its normal course of business.
