Mahler Fields #1198
Roberts County · Mendota NW. (Granite Wash SW.) field · Shut IN · Vertical
Mahler Fields #1198 (API 42-393-31738) is a well in Roberts County operated by Mmgl Txph LLC, completed November 30, 2005 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 26, 2005, permitted to 11,000 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Mmgl Txph LLC on the wellbore schedule.
Completion filings report one formation top, including Granite Wash.
Its lease has reported 177K barrels of oil and 3.13M mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
Operator of record
