Prentice (6700 Clearfork) Unit #321 (API 42-445-30926) is a well in Terry County operated by Occidental Permian Ltd., completed February 1, 2023 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued April 10, 1981, permitted to 7,100 ft.
It was permitted by Tenneco Oil CO. and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 4 formation tops, including Tansill, Yates, Grayburg, Clear Fork.
Its lease has reported 13.3M barrels of oil and 2.74M mcf of gas since January 1993, last reporting in July 2026. The lease carries 183 wells, so these are lease totals, not this well alone.
