Reserves

At Sept. 30, 2019, proved reserves were 106.4 Bcfe, as calculated by DeGolyer and MacNaughton, the Company’s independent consulting petroleum engineering firm. This was a 39% decrease, compared to the 173.6 Bcfe of proved reserves at Sept. 30, 2018. Total proved developed reserves decreased 19% to 89.4 Bcfe, as compared to Sept. 30, 2018, reserve volumes, mainly due to 2019 production and pricing and performance revisions. The performance revisions were principally due to lower performance of our high-interest Woodford natural gas wells drilled in 2017 in the Arkoma Stack and, to a lesser extent, lower performance of the Fayetteville Shale natural gas properties in Arkansas. Total proved undeveloped reserves decreased 46.9 Bcfe principally due to the Company implementing the new strategy of not participating with a working interest in future drilling programs, which resulted in the removal of undeveloped leasehold wells (including the Eagle Ford Shale wells) and lowering the net revenue interest on previously planned working interest wells on our mineral acreage to a royalty revenue interest only. SEC prices used for the Sept. 30, 2019, report averaged $2.48 per Mcf for natural gas, $54.40 per barrel for oil and $19.30 per barrel for NGL, compared to $2.56 per Mcf for natural gas, $62.86 per barrel for oil and $26.13 per barrel for NGL for the Sept. 30, 2018, report. These prices reflect net prices received at the wellhead.
