Wharton County · Pierce Ranch (4900) field · Vertical
Pierce Estate #4 (API 42-481-32370) is a well in Wharton County operated by Mcgowan Working Partners Inc., completed August 21, 1982.
The RRC has issued 2 drilling permits between 1982 and 1988, permitted to 6,900 ft.
It was permitted by Armour Resource Holdings, Ltd. and has since transferred to Mcgowan Working Partners Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Miocene (undifferentiated), Frio, Vicksburg.
Its 3 leases have reported 659K barrels of oil and 1.04M mcf of gas since January 1993, last reporting in July 2026. The leases carry 21 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 467K barrels injected in the 12 months reported through June 2025.
