Hockley County · Yellowhouse S. (San Andres) field · Injection · Vertical
Combs Sam #4 (API 42-219-35744) is a well in Hockley County operated by Sixess Energy LLC, completed August 7, 1991 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued April 23, 1991, permitted to 5,000 ft.
It was permitted by Walsh Petroleum, Inc. and has since transferred to Sixess Energy LLC on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 123K barrels of oil and 68.1K mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 13.5K barrels injected in the 12 months reported through March 2026.
