Mildred #3 (API 42-317-34252) is a well in Martin County operated by Pioneer Natural Res. USA Inc., completed March 4, 2009 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 4, 2000, permitted to 8,900 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 Spraberry, U. Spraberry, L. Spraberry, 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.

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