Yellowhouse Unit #121 (API 42-219-35248) is a well in Hockley County operated by Hilcorp Energy Company, completed February 22, 1988 and listed as shut in on the RRC schedule, shut in June 1, 2021.

The RRC has issued one drilling permit, issued January 20, 1988, permitted to 4,692 ft.

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

Completion filings report 2 formation tops, including Rustler, San Andres.

Its lease has reported 3.12M barrels of oil and 516K mcf of gas since January 1993, last reporting in July 2026. The lease carries 127 wells, so these are lease totals, not this well alone.
