Edwards 127 #23 (API 42-503-41384) is a well in Young County operated by Mammoth Operating LLC, completed March 19, 2010 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued December 28, 2006, permitted to 550 ft.

It was permitted by J-Lyn Oil CO. and has since transferred to Mammoth Operating LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Gunsite, Gunsight.

Its lease has reported 68.6K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 20 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 1.42K barrels injected in the 12 months reported through November 2025.

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