Winterbotham Heirs #1 (API 42-235-33576) is a well in Irion County operated by Apex Operating Partners LLC, completed December 3, 1996 and listed as producing on the RRC schedule, shut in August 1, 2026.
The RRC has issued one drilling permit, issued October 21, 1996, permitted to 6,425 ft.
It was permitted by Strand Energy, L.C. and has since transferred to Apex Operating Partners LLC on the wellbore schedule.
Completion filings report 7 formation tops, including T/San Angelo Sd, B/Coleman Junction, T/Coleman Junction, T/Clearfork.
Its 2 leases have reported 196 barrels of oil and 1.59M mcf of gas since November 1996, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
