Milo E. F. #9F
Harris County · Tomball (Schultz SE.) field · Producing · Vertical
Milo E. F. #9F (API 42-201-00643) is a well in Harris County operated by Tandem Energy Corporation, completed May 20, 1986 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 3, 1979, permitted to 6,538 ft.
It was permitted by Exxon Corp. and has since transferred to Tandem Energy Corporation on the wellbore schedule.
Its 2 leases have reported 502K barrels of oil and 965K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Exxon Corp.; the EWA schedule now lists a different operator.
