Yoakum County · Brahaney Northwest (Devonian) field · Vertical
Read #4 (API 42-501-33270) is a well in Yoakum County operated by Extex Operating Company, completed June 13, 1989.
The RRC has issued 3 drilling permits between 1987 and 2008, permitted to 12,100 ft.
It was permitted by Pyr Energy Corporation and has since transferred to Extex Operating Company on the wellbore schedule.
Completion filings report 8 formation tops, including San Andres, Tubb, Wolfcamp, Strawn.
Its 3 leases have reported 620K barrels of oil and 77.2K 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.
