Central Robertson Clearfork Unit #1155W (API 42-165-38430) is a well in Gaines County operated by Hilcorp Energy Company, completed November 23, 2016 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued August 16, 2016, permitted to 7,405 ft.

It was permitted by Occidental Permian Ltd. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 9 formation tops, including Rustler, Yates, Seven Rivers, Queen.

Its lease has reported 19.6M barrels of oil and 7.81M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 154 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 20.3K barrels injected in the 12 months reported through October 2025.

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