Lambshead C-9 #1 (API 42-447-35196) is a well in Throckmorton County operated by Breck Operating Corp., completed October 7, 1991.
The RRC has issued 2 drilling permits (amended once) between 1991 and 2005, permitted to 5,000 ft.
It was permitted by Encon Services, Inc. and has since transferred to Breck Operating Corp. on the wellbore schedule.
Completion filings report 2 formation tops, including Caddo, Mississippian.
Its 2 leases have reported 35K barrels of oil and 414K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
