Chambers Frank M. ET AL -C- #8 (API 42-393-31028) is a well in Roberts County operated by Mmgl Txph LLC, completed May 8, 1990 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1984 and 1986, permitted to 12,296 ft.
It was permitted by Diamond Shamrock Exploration CO. and has since transferred to Mmgl Txph LLC on the wellbore schedule.
Completion filings report 26 formation tops, including Bd, Brown Dolomite, Doug, Douglas.
Its 2 leases have reported 24.5K barrels of oil and 2.75M mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
