Bexar County · Somerset field · Producing · Vertical
Weir-Rambie #9 (API 42-029-36259) is a well in Bexar County operated by Calfas Oil LLC, completed March 26, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 15, 1985, permitted to 2,100 ft.
It was permitted by MR Oil Company and has since transferred to Calfas Oil LLC on the wellbore schedule.
Completion filings report one formation top, including Olmos.
Its lease has reported 31.2K barrels of oil and 70 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 Mr Oil Company; the EWA schedule now lists a different operator.
