Greenlee Heirs #4 (API 42-383-33990) is a plugged well in Reagan County, plugged May 16, 2024, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued one drilling permit, issued January 12, 1990, permitted to 8,000 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 Cretaceous, Spraberry, Dean.

Its lease has reported 93.2K barrels of oil and 1.13M mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 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.
