Young County · Young County Regular field · Producing · Vertical
Mcclurg M. L. #7 (API 42-503-42426) is a well in Young County operated by Mammoth Operating LLC, completed March 8, 2019 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 7, 2019, permitted to 750 ft.
It was permitted by J-Lyn Oil CO. and has since transferred to Mammoth Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Gunsight.
Its lease has reported 4.46K barrels of oil and 43 mcf of gas since January 1993, last reporting in July 2026. The lease carries 12 wells, so these are lease totals, not this well alone.
