Blue Topaz State Unit 251-252w #4H (API 42-389-39489) is a horizontal well in Reeves County operated by Apache Corporation, completed October 15, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 12, 2021, permitted to 13,000 ft.

It was permitted by Primexx Operating Corporation and has since transferred to Apache Corporation on the wellbore schedule.

Completion filings report 8 formation tops, including Castile, Delaware, Bell Canyon, Cherry Canyon.

Its lease has reported 2.13M barrels of oil and 4.4M mcf of gas since June 2019, last reporting in July 2026. The lease carries 6 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.
