Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company is a corporation and it is subject to U.S. federal income tax. The tax implications of the IPO and the Company’s concurrent corporate reorganization, and the tax impact of the Company’s status as a taxable corporation subject to U.S. federal income tax have been reflected in the accompanying condensed consolidated financial statements. The effective combined U.S. federal and state income tax rate applicable to the Company for the nine months ended September 30, 2016 was 28.4%. During the three months ended September 30, 2016 and 2015, the Company recognized an income tax benefit of $1.3 million and an income tax expense of $0.6 million, respectively. During the nine months ended September 30, 2016 and 2015, the Company recognized an income tax benefit of $21.8 million and $15.1 million, respectively. Total income tax benefit (expense) for the three and nine months ended September 30, 2016 differed from amounts computed by applying the U.S. federal statutory tax rate of 35% due primarily to the impact of net (loss) income attributable to noncontrolling ownership interests as well as the impact of state income taxes. As a result of the exchange of PE Units (and corresponding shares of Class B Common Stock) for Class A Common Stock discussed in Note 12—Related Party Transactions, the Company recorded additional net deferred tax liability of $6.0 million associated with the change in its investment in Parsley LLC. As a result of the Equity Offering discussed in Note 1—Organization and Nature of Operations, the Company’s statutory rate related to certain tax and book basis timing differences increased by 0.2%, calculated by multiplying the 0.6% increase in the Company’s ownership of Parsley LLC by the Company’s federal tax rate of 35%. As a result, the Company recorded additional deferred tax liability of $2.8 million during the three months ended September 30, 2016. The Company early adopted ASU 2016-09 effective January 1, 2016, which resulted in a favorable adjustment for the net excess income tax benefits from stock-based compensation during the nine months ended September 30, 2016. The adoption was on a prospective basis and therefore had no impact on prior years. The Company also recorded an adjustment to opening retained earnings of $0.1 million to recognize U.S. net operating loss carryforwards attributable to excess tax benefits on stock-based compensation that had not been previously recognized to additional paid in capital because they did not reduce income taxes payable.
