Vollmert J. C. #2 (API 42-393-30710) is a well in Roberts County operated by Mmgl Txph LLC, completed July 28, 1979 and listed as swr-10-well on the RRC schedule, shut in October 1, 2020.

The RRC has issued one drilling permit, issued June 5, 1979, permitted to 10,895 ft.

It was permitted by Exxon Corp. and has since transferred to Mmgl Txph LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Permian (undifferentiated), Wolfcamp, Pennsylvanian, Douglas.

Its 4 leases have reported 10.4K barrels of oil and 612K mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
