Fullerton Clearfork Unit #1686 (API 42-003-34458) is a well in Andrews County operated by Hilcorp Energy Company, completed October 10, 1990 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued August 31, 1984, permitted to 7,404 ft.

It was permitted by Exxon Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 4 formation tops, including Clear Fork, Tubb, Upper Staining, Wichita-Albany.

Its lease has reported 77.4M barrels of oil and 65.6M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 1,406 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 95.1K barrels injected in the 12 months reported through March 2026.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
