WELL · 42-067-30477 · DISTRICT 6
Walker #1
Cass County · Hosey-Driskell (Rodessa) field · Vertical
Walker #1 (API 42-067-30477) is a well in Cass County operated by Diamond A Inc., completed July 5, 1984.
The RRC has issued one drilling permit, issued May 11, 1984, permitted to 6,400 ft.
It was permitted by Pitts Oil CO.-Dallas Prod. Inc. and has since transferred to Diamond A Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Massive Anhydrite (marker), B. Massive Anhydrite, Rodessa.
Its 2 leases have reported 443K barrels of oil and 121K mcf of gas since January 1993, last reporting in July 2026. The leases carry 29 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
