Miller D. #8
Bexar County · Fairfield field · Producing · Vertical
Miller D. #8 (API 42-029-37116) is a well in Bexar County operated by Calk Oil Company, completed February 19, 1986 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 14, 1986, permitted to 1,325 ft.
It was permitted by CG Oil CO. and has since transferred to Calk Oil Company on the wellbore schedule.
Completion filings report one formation top, including Anachoca.
Its lease has reported 25K barrels of oil and 20 mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by CG Oil Co.; the EWA schedule now lists a different operator.
