FT. Stockton South Unit #4201W (API 42-371-04874) is a disposal or injection well in Pecos County operated by Durango Resources Corp. under an active UIC permit.

The RRC has issued one drilling permit (amended once), issued August 4, 1999, permitted to 3,350 ft.

It was permitted by Apache Corporation and has since transferred to Durango Resources Corp. on the wellbore schedule.

Its lease has reported 3.87M barrels of oil and 1.63M mcf of gas since January 1993, last reporting in July 2026. The lease carries 181 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 160K barrels injected in the 12 months reported through May 2026.
