Robertson /Clearfork/ Unit #303W (API 42-165-38316) is a well in Gaines County operated by Hilcorp Energy Company, completed April 24, 2015 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued April 2, 2015, permitted to 7,400 ft.

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

Completion filings report 10 formation tops, including Yates, Seven Rivers, San Andres, Glorieta.

Its lease has reported 21.5M barrels of oil and 11.5M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 486 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 9.64K barrels injected in the 12 months reported through October 2025.
