Yturria L & L #2
Starr County · Yturria NE. (5000 Sand) field · Vertical
Yturria L & L #2 (API 42-427-31945) is a former disposal or injection well in Starr County, last operated by Trap Rock Oil Ltd.; its UIC permit is no longer active.
The RRC has issued 4 drilling permits between 1984 and 1993, permitted to 8,000 ft.
It was permitted by Merit Energy Company and has since transferred to Trap Rock Oil Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Frio, Vickburg, Vicksburg.
Its 4 leases have reported 50.1K barrels of oil and 62K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Merit Energy Company; the EWA schedule now lists a different operator.
