Mask #18 (API 42-059-37024) is a well in Callahan County operated by Sandstone Services LLC, completed April 25, 2014 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued April 22, 2014, permitted to 500 ft.

It was permitted by Rg1 Energy, LLC and has since transferred to Sandstone Services LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Bunger - Disposal, Caddo, Cisco, Coleman Junction.

Its lease has reported 2.8K barrels of oil and 110 mcf of gas since January 1993, last reporting in July 2026. The lease carries 14 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.
