East Mrs. S.K. B #75 (API 42-261-31401) is a well in Kenedy County operated by Hilcorp Energy Company, completed May 18, 2022 and listed as producing on the RRC schedule.

The RRC has issued 3 drilling permits between 2006 and 2011, permitted to 17,500 ft.

It was permitted by Newfield Exploration Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 12 formation tops, including Miocene (undifferentiated), Catahoula, Nod B, Frio.

Its 4 leases have reported 1.12K barrels of oil and 7.49M mcf of gas since September 2006, last reporting in July 2026. The leases carry 4 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.
