Throckmorton County · Big Buffalo (Mississippian) field · Injection · Vertical
Lambshead C 10 #2 (API 42-447-35267) is a well in Throckmorton County operated by Petex, completed May 7, 1997 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued April 8, 1992, permitted to 5,500 ft.
It was permitted by Throckmorton Oil, Inc. and has since transferred to Petex on the wellbore schedule.
Its lease has reported 51.1K barrels of oil and 33.9K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 13K barrels injected in the 12 months reported through August 2025.
