Pryor Ranch #35 (API 42-507-31553) is a well in Zavala County operated by Mcday Energy Corp., completed December 9, 1982 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued August 12, 1981, permitted to 3,250 ft.
It was permitted by Winn Exploration/Dulce Company and has since transferred to Mcday Energy Corp. on the wellbore schedule.

Its lease has reported 51.2K barrels of oil and 1.78K mcf of gas since January 1993, last reporting in July 2026. The lease carries 17 wells, so these are lease totals, not this well alone.
