Vollmert J. C. #4
Roberts County · Mendota NW. (Douglas Lo.) field · Shut In · Vertical
Vollmert J. C. #4 (API 42-393-30901) is a well in Roberts County operated by Mmgl Txph LLC, completed April 16, 1982 and listed as shut in on the RRC schedule, shut in September 1, 2009.
The RRC has issued one drilling permit, issued December 31, 1981, permitted to 7,460 ft.
It was permitted by Exxon Corp. and has since transferred to Mmgl Txph LLC on the wellbore schedule.
Its lease has reported 10.4K barrels of oil and 394K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
