Mahler #2 (API 42-393-30694) is a well in Roberts County operated by Unit Petroleum Company, completed September 24, 2025 and listed as shut in on the RRC schedule, shut in February 1, 2012.
The RRC has issued one drilling permit, issued March 13, 1979, permitted to 10,600 ft.
It was permitted by Amoco Production Company and has since transferred to Unit Petroleum Company on the wellbore schedule.
Completion filings report 4 formation tops, including Douglas, Tonkawa, Granite Wash, Atoka.
Its lease has reported 119K barrels of oil and 2.5M mcf of gas since the record begins in January 1993, with no volume in the three years through August 2026. The lease carries 8 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
