Throckmorton County · Throckmorton County Regular field · Injection · Vertical
Mclemore A-330 #22S (API 42-447-35510) is a well in Throckmorton County operated by WB Mullin Operating LLC, completed October 31, 1994 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued October 17, 1994, permitted to 500 ft.
It was permitted by Throckmorton Oil, Inc. and has since transferred to WB Mullin Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Tannehill.
Its lease has reported 122K barrels of oil and 29 mcf of gas since September 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 15K barrels injected in the 12 months reported through August 2025.
