Main-Matysek Unit #1A
Wilbarger County · Main (Canyon) field · Producing · Vertical
Main-Matysek Unit #1A (API 42-487-31814) is a well in Wilbarger County operated by Enr Operating LLC, completed February 7, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 17, 1984, permitted to 4,300 ft.
It was permitted by Wortham, E. H. and has since transferred to Enr Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Canyon.
Its lease has reported 48K barrels of oil and 22 mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Wortham, E. H.; the EWA schedule now lists a different operator.
