Willis #7 (API 42-329-34310) is a plugged well in Midland County, plugged May 11, 2026, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued one drilling permit, issued May 25, 2000, permitted to 9,100 ft.

It was permitted by Cox, John L. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Redbeds, Spraberry, Dean.

Its lease has reported 117K barrels of oil and 307K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 9 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.
