Reserves

At Sept. 30, 2021, proved reserves were 83.0 Bcfe, as calculated by DeGolyer and MacNaughton, the Company’s independent consulting petroleum engineering firm. This was a 44% increase, compared to the 57.7 Bcfe of proved reserves at Sept. 30, 2020. Total proved developed reserves increased 42% to 77.7 Bcfe, as compared to Sept. 30, 2020 reserve volumes, mainly due to 2021 pricing revisions, partially offset by production and performance revisions. The pricing revisions were due to well economic limits extending later than was projected in 2020 as a result of higher gas and oil prices. The performance revisions were principally due to lower performance of high-interest Mississippian and Woodford wells in the STACK play in Oklahoma that were brought online in 2021. Total proved undeveloped reserves increased 2.2 Bcfe, principally due to mineral interest acquisitions in the Haynesville Shale in Texas and Louisiana and Meramec and Woodford SCOOP play in Oklahoma. SEC prices used for the Sept. 30, 2021, report averaged $2.79 per Mcf for natural gas, $56.51 per barrel for oil and $20.58 per barrel for NGL, compared to $1.62 per Mcf for natural gas, $40.18 per barrel for oil and $9.95 per barrel for NGL for the Sept. 30, 2020, report. These prices reflect net prices received at the wellhead.
