Gaston L. W. #7 (API 42-455-30475) is a well in Trinity County operated by HD Operating CO LLC, completed June 30, 2021 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 24, 2003, permitted to 4,600 ft.
It was permitted by Range Production Company and has since transferred to HD Operating CO LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Weches, Queen City, Recklaw, Reclaw.
Its lease has reported 147K barrels of oil and 184K mcf of gas since February 1996, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 83.6K barrels injected in the 12 months reported through March 2026.
