Pryor Ranch #177
Zavala County · Winn-Dulce (Olmos 2600) field · Shut In-Multi-Compl · Vertical
Pryor Ranch #177 (API 42-507-31944) is a well in Zavala County operated by Mcday Energy Corp., completed April 26, 1983 and listed as shut in-multi-compl on the RRC schedule, shut in July 1, 2000.
The RRC has issued one drilling permit, issued April 7, 1983, permitted to 3,025 ft.
It was permitted by Winn Exploration/Dulce Company and has since transferred to Mcday Energy Corp. on the wellbore schedule.
Its 2 leases have reported 853 mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
