Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Drilling and Completion Commitments In March 2020, we provided termination notices releasing our contracted drilling rigs in connection with the suspension of our drilling and completion program. There were no material charges associated with the rig releases. In April 2020, we rescinded one of the termination notices and entered into a new agreement to maintain one rig in place for a minimal daily rate providing us with the option to either restart drilling operations on seven days notice or release the rig altogether for demobilization. We also have a one-year agreement that became effective January 1, 2020, which can be terminated with 30 days’ notice by either party, for certain frac services and related materials, with no minimum commitment. While this agreement remains in effect, we are not incurring any costs thereunder after April 10, 2020 due to the suspension of the drilling and completion program. Gathering and Intermediate Transportation Commitments We have long-term agreements with Nuevo Dos Gathering and Transportation, LLC (“Nuevo G&T”) and Nuevo Dos Marketing, LLC (“Nuevo Marketing” and together with Nuevo G&T, collectively “Nuevo”) to provide gathering and intermediate pipeline transportation services for a substantial portion of our crude oil and condensate production in South Texas as well as volume capacity support for certain downstream interstate pipeline transportation. Nuevo is obligated to gather and transport our crude oil and condensate from within a dedicated area in the Eagle Ford via a gathering system and intermediate takeaway pipeline connecting to a downstream interstate pipeline operated by a third party through 2041. We have a minimum volume commitment (“MVC”) of 8,000 gross barrels of oil per day to Nuevo through 2031 under the gathering agreement. Under a marketing agreement, we have a commitment to sell 8,000 barrels per day of crude oil (gross) to Nuevo, or to any third party, utilizing Nuevo Marketing’s capacity on a downstream interstate pipeline through 2026. Under each of the agreements with Nuevo, credits for deliveries of volumes in excess of the volume commitment may be applied to any deficiency arising in the succeeding 12-month period. Excluding the application of existing credits that we have earned during the preceding 12-month period ended March 31, 2020 for deliveries of volumes in excess of the volume commitment, and the potential impact of the effects of price escalation from commodity price changes, if any, the minimum fee requirements attributable to the MVC under the gathering and transportation agreement are as follows: $9.7 million for the remainder of 2020, $13.0 million for 2021 through 2025, $7.4 million for 2026, $3.8 million per year for 2027 through 2030 and $2.2 million for 2031. Legal and Environmental Compliance We are involved, from time to time, in various legal proceedings arising in the ordinary course of business. While the ultimate results of these proceedings cannot be predicted with certainty, our management believes that these claims will not have a material effect on our financial position, results of operations or cash flows. As of March 31, 2020, we had a reserve in the amount of $0.3 million included in “Accounts payable and accrued liabilities” for the estimated settlement of a dispute with a partner regarding certain transactions that occurred in prior years. As of March 31, 2020, we had AROs of approximately $5.1 million attributable to the plugging of abandoned wells.
