Comeback Lease #2
Throckmorton County · Throckmorton County Regular field · Injection · Vertical
Comeback Lease #2 (API 42-447-35636) is a well in Throckmorton County operated by Leahy Oil LLC, completed September 3, 2008 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued July 9, 1996, permitted to 978 ft.
It was permitted by Cooper Oil & Gas, Inc. and has since transferred to Leahy Oil LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Sedwick Lime, Tannehill.
Its lease has reported 49.7K barrels of oil and 2 mcf of gas since October 1994, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 963 barrels injected in the 12 months reported through August 2025.
