Chisom W.A. #1 (API 42-143-30441) is a well in Erath County operated by Greenhaw Morris R Oil & Gas Inc, completed March 1, 1979.
The RRC has issued one drilling permit, issued January 16, 1979, permitted to 3,400 ft.
It was permitted by Penn Petroleum Inc. and has since transferred to Greenhaw Morris R Oil & Gas Inc on the wellbore schedule.
Its 2 leases have reported 340 barrels of oil and 72.4K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
