Merchant Unit #158 (API 42-383-33311) is a plugged well in Reagan County, plugged May 6, 1993, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued 2 drilling permits between 1984 and 1990, permitted to 8,250 ft.
It was permitted by Oxy USA Inc. 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 volume in April 2026. The lease carries 200 wells, so these are lease totals, not this well alone.
