Weir W. C. Estate -A- #4 (API 42-433-10080) is a plugged well in Stonewall County, plugged October 25, 2011, last operated by Marathon Oil Company.

The RRC has issued one drilling permit, issued May 10, 2016, permitted to 4,750 ft.

It was permitted by L.C.S. Production Company and has since transferred to Marathon Oil Company on the wellbore schedule.

Completion filings report 4 formation tops, including Coleman Junction, Tannehill, Stockwether, Canyon.

Its lease has reported 637K barrels of oil and 377K mcf of gas since January 1993, last reporting in July 2026. The lease carries 75 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.
