Montague County · M P S (Ellenburger) field · Producing · Vertical
Donald & Donald #4 (API 42-337-33750) is a well in Montague County operated by Large Operating LLC, completed April 8, 2006 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 12, 2005, permitted to 7,500 ft.
It was permitted by Glahn Resources, Inc. and has since transferred to Large Operating LLC on the wellbore schedule.
Its lease has reported 28.4K barrels of oil and 344K mcf of gas since January 2006, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
