Tankersley #1 (API 42-235-32659) is a plugged well in Irion County, plugged July 31, 1995, last operated by Breitburn Operating L.P..

The RRC has issued one drilling permit, issued September 13, 1985, permitted to 7,100 ft.

It was permitted by Indian Wells Oil Company and has since transferred to Breitburn Operating L.P. on the wellbore schedule.

Completion filings report 6 formation tops, including Base Cretaceous (marker), San Angelo, Clear Fork, Leonard.

Its lease has reported 13.7K barrels of oil and 479K mcf of gas since January 1993, last reporting in March 2015. The lease carries 7 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
