Pecos County · Sun Valley (Tubb Lower) field · Horizontal
State Houston CO. Timber CO. -A- #7H (API 42-371-31399) is a horizontal well in Pecos County operated by Last Mile Production LLC, completed September 19, 2012.
The RRC has issued 2 drilling permits between 2012 and 2018, permitted to 4,000 ft.
It was permitted by Iskandia Energy Operating, Inc. and has since transferred to Last Mile Production LLC on the wellbore schedule.
Completion filings report 4 formation tops, including San Andres, Glorieta, Clear Fork, Tubb.
Its 2 leases have reported 135K barrels of oil and 144K mcf of gas since January 1993, last reporting in July 2026. The leases carry 16 wells, so these are lease totals, not this well alone.
