Merchant Unit #4207A (API 42-383-34318) is a plugged well in Reagan County, plugged September 18, 2019, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued one drilling permit, issued December 2, 1994, permitted to 8,250 ft.

It was permitted by Parker & Parsley Development CO. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Completion filings report 2 formation tops, including Spraberry, Dean.

Its lease has reported 6.36M barrels of oil and 36.8M mcf of gas since January 1993, last reporting in July 2026. The lease carries 200 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.
