Yoakum County · Ownby (Clear Fork Upper) field · Producing · Vertical
Central Ownby Unit #1 (API 42-501-31963) is a well in Yoakum County operated by Occidental Permian Ltd., completed June 16, 1981 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits in 1981, permitted to 7,000 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Its 2 leases have reported 12.3M barrels of oil and 2.68M mcf of gas since January 1993, last reporting in July 2026. The leases carry 158 wells, so these are lease totals, not this well alone.
