Gist -B- #520 (API 42-135-35562) is a well in Ector County operated by Aghorn Operating Inc., completed April 15, 1990 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued May 15, 1987, permitted to 4,361 ft.

It was permitted by Kerr-Mcgee Corporation and has since transferred to Aghorn Operating Inc. on the wellbore schedule.

Completion filings report 7 formation tops, including Top Anhydrite, Cowden Anhydrite, Cownen Anhydrite, Yates.

Its lease has reported 718K barrels of oil and 159K mcf of gas since January 1993, last reporting in July 2026. The lease carries 22 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.
