Wright #4A
Howard County · Middleton (Canyon Reef) field · Vertical
Wright #4A (API 42-227-34702) is a plugged well in Howard County, plugged March 2, 2013, last operated by Cobra Oil & Gas Corporation.
The RRC has issued 2 drilling permits between 1992 and 2016, permitted to 9,100 ft.
It was permitted by P4 Operating, LLC and has since transferred to Cobra Oil & Gas Corporation on the wellbore schedule.
Completion filings report 12 formation tops, including San Andres, Glorieta, Clear Fork, Spraberry.
Its 3 leases have reported 592K barrels of oil and 437K mcf of gas since January 1993, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 2.44M barrels injected in the 12 months reported through December 2025.
