Westbrook J. C. #4 (API 42-097-20186) is a disposal or injection well in Cooke County operated by ST. Cajetan Oil Company LLC under an active UIC permit.
The RRC has issued one drilling permit, issued June 18, 2009, permitted to 3,300 ft.
It was permitted by Taylor & Smith and has since transferred to ST. Cajetan Oil Company LLC on the wellbore schedule.
Its lease has reported 48.3K barrels of oil and 4.43K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 33.5K barrels injected in the 12 months reported through August 2025.
Operator of record
Permitted by Taylor & Smith; the EWA schedule now lists a different operator.
