Mills-Strain Unit #507 (API 42-335-33587) is a well in Mitchell County operated by Schlachter Operating Corporation, completed May 25, 2005 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued July 24, 1992, permitted to 1,750 ft.
It was permitted by Grand Banks Energy Company and has since transferred to Schlachter Operating Corporation on the wellbore schedule.
Completion filings report 2 formation tops, including Yates, San Andres.
Its lease has reported 1.45M barrels of oil and 27 mcf of gas since January 1993, last reporting in July 2026. The lease carries 120 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 13.2K barrels injected in the 12 months reported through July 2025.
