Andrews County · Fullerton field · Shut In · Vertical
Fullerton Clearfork Unit #1566 (API 42-003-36802) is a well in Andrews County operated by Hilcorp Energy Company, completed December 19, 2012 and listed as shut in on the RRC schedule, shut in June 1, 2026.
The RRC has issued 2 drilling permits (amended once) in 1990, permitted to 8,573 ft.
It was permitted by Exxon Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 2 formation tops, including Clear Fork, Tubb.
Its lease has reported 76.9M barrels of oil and 65.2M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 1,406 wells, so these are lease totals, not this well alone.
