Martin County · Spraberry (Trend Area) field · Shut In · Vertical
Mildred #2 (API 42-317-34224) is a well in Martin County operated by Pioneer Natural Res. USA Inc., completed August 1, 2025 and listed as shut in on the RRC schedule, shut in April 1, 2020.
The RRC has issued one drilling permit, issued June 15, 1999, permitted to 8,930 ft.
It was permitted by Concho Resources Inc. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including T. Upper Spraberry, Spraberry, T. Lower Spraberry, T. Jo Mill.
Its lease has reported 97.4K barrels of oil and 234K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
