The RRC has issued 3 drilling permits (amended once) between 1990 and 2000, permitted to 4,550 ft.
It was permitted by Southwestern Energy Prod. CO. and has since transferred to Texas Petroleum Investment CO. on the wellbore schedule.
Completion filings report 7 formation tops, including Whitsett, Mcelroy, Caddell, Yegua.
Its 3 leases have reported 69.1K barrels of oil and 229K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
