Kolb 31-5 #10 (API 42-003-46492) is a well in Andrews County operated by Sabalo II Operating LLC, completed September 26, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 11, 2014, permitted to 9,695 ft.

It was permitted by Williams, Clayton Energy, Inc. and has since transferred to Sabalo II Operating LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Yates, Seven Rivers, Queen, Grayburg.

Its lease has reported 1.02M barrels of oil and 2.15M mcf of gas since June 2010, last reporting in July 2026. The lease carries 15 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.
