Matthews J. B. #12 (API 42-447-36488) is a well in Throckmorton County operated by Salty Lime Energy LLC, completed July 23, 2013 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit, issued May 22, 2013, permitted to 1,200 ft.
It was permitted by Chateau Oil And Gas Inc. and has since transferred to Salty Lime Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Upper Cook, Lower Cook, Hope.
Its lease has reported 23.5K barrels of oil and 180 mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
