Mead Milton O. #9 (API 42-029-35937) is a plugged well in Bexar County, plugged November 13, 2025, last operated by Calfas Cattle & Oil LLC.

The RRC has issued one drilling permit, issued November 27, 1984, permitted to 1,600 ft.

It was permitted by Caltate Energy Corp. and has since transferred to Calfas Cattle & Oil LLC on the wellbore schedule.

Completion filings report one formation top, including Olmos.

Its lease has reported 1.53K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
