At Sept. 30, 2020, proved reserves were 57.7 Bcfe, as calculated by DeGolyer and MacNaughton, the Company’s independent consulting petroleum engineering firm. This was a 46% decrease, compared to the 106.4 Bcfe of proved reserves at Sept. 30, 2019. Total proved developed reserves decreased 39% to 54.6 Bcfe, as compared to Sept. 30, 2019, reserve volumes, mainly due to 2020 production and pricing and performance revisions. The pricing revisions were due to wells reaching their economic limits earlier than projected in 2019. The performance revisions were principally due to lower performance of the Company’s high-interest Woodford natural gas wells in the STACK and Arkoma Stack in Oklahoma and, to a lesser extent, lower performance of the Eagle Ford Shale oil properties in southern Texas. Total proved undeveloped reserves decreased 14.0 Bcfe principally due to the impact of COVID-19 and reduced pricing leading to an unprecedented decrease in operator activity in 2020 and a decision to remove PUD locations not permitted, in progress, or drilled and uncompleted (DUC). SEC prices used for the Sept. 30, 2020, report averaged $1.62 per Mcf for natural gas, $40.18 per barrel for oil and $9.95 per barrel for NGL, compared to $2.48 per Mcf for natural gas, $54.40 per barrel for oil and $19.30 per barrel for NGL for the Sept. 30, 2019, report. These prices reflect net prices received at the wellhead.
