Bitler-Lowe Clearfork Unit #12B (API 42-003-36935) is a permitted well in Andrews County filed by Maralo, Inc.; no completion report is on file yet.

The RRC has issued one drilling permit, issued May 24, 1991, permitted to 7,200 ft.

It was permitted by Maralo, Inc. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Rustler, Yates, San Andres, Ucf.

Its lease has reported 2.57M barrels of oil and 1.15M mcf of gas since January 1993, last reporting in July 2026. The lease carries 50 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.
