Fullerton Clearfork Unit #1880 (API 42-003-35968) is a well in Andrews County operated by Hilcorp Energy Company, completed September 4, 1988 and listed as shut in on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1987 and 1988, permitted to 8,600 ft.
It was permitted by Exxon Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, San Andres, Clear Fork.
Its lease has reported 76.9M barrels of oil and 65.2M mcf of gas since January 1993, last reporting in July 2026. The lease carries 1,406 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
