Blaha A. #4A (API 42-287-31689) is a well in Lee County operated by M. K. Production, completed August 11, 1984.
The RRC has issued one drilling permit, issued August 15, 1984, permitted to 5,200 ft.
It was permitted by Austin Oil & Mineral and has since transferred to M. K. Production on the wellbore schedule.

Its 2 leases have reported 43.8K barrels of oil and 76.2K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
