Big Foot Olmos B Sand Unit #407A (API 42-163-32338) is a well in Frio County operated by Maverick Energy Group Inc., completed September 4, 1984 and listed as shut in on the RRC schedule, shut in February 1, 2022.

The RRC has issued one drilling permit, issued July 19, 1984, permitted to 3,900 ft.

It was permitted by Shell Western E&P Inc. and has since transferred to Maverick Energy Group Inc. on the wellbore schedule.

Completion filings report 4 formation tops, including Wilcox, Midway, Navarro, Olmos.

Its lease has reported 2.04M barrels of oil and 474K mcf of gas since the record begins in January 1993, with no volume in the three years through August 2026. The lease carries 470 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
