Robertson /Clearfork/ Unit #4103 (API 42-165-32535) is a well in Gaines County operated by Hilcorp Energy Company, completed August 21, 2014 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued March 29, 1983, permitted to 7,300 ft.

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

Completion filings report 8 formation tops, including Rustler, Salado, Yates, Seven Rivers.

Its lease has reported 21.7M barrels of oil and 11.6M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 486 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 38 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.
