Lambshead C-8 #12S (API 42-447-35717) is a well in Throckmorton County operated by T-N-T Engineering Inc., completed July 25, 1997.
The RRC has issued one drilling permit, issued February 28, 1997, permitted to 2,000 ft.
It was permitted by L.C.S. Production Company and has since transferred to T-N-T Engineering Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Dothan, Saddle Creek, Cook Sand.
Its 2 leases have reported 80.2K barrels of oil and 4 mcf of gas since October 1995, last reporting in July 2026. The leases carry 12 wells, so these are lease totals, not this well alone.
