Mahler -B- #1 (API 42-393-30104) is a plugged well in Roberts County, plugged May 22, 2007, last operated by BP America Production Company.
The RRC has issued one drilling permit, issued November 28, 1990, permitted to 11,570 ft.
It was permitted by Phillips Petroleum Company and has since transferred to BP America Production Company on the wellbore schedule.
Completion filings report 6 formation tops, including Brown Dolomite, Cleveland, Granite Wash, Cherokee.
Its 3 leases have reported 31 barrels of oil and 68.7K mcf of gas since January 1993, last reporting in May 2007. The leases carry 2 wells, so these are lease totals, not this well alone.
