Webb County · Big Cowboy (Wilcox 5100) field · Vertical
Lessor Mary Etta #4 (API 42-479-34064) is a plugged well in Webb County, plugged March 11, 2004, last operated by Conocophillips Company.
The RRC has issued 3 drilling permits between 1984 and 1997, permitted to 7,300 ft.
It was permitted by Conoco Inc. and has since transferred to Conocophillips Company on the wellbore schedule.
Completion filings report 2 formation tops, including Queen City, Wilcox.
Its 2 leases have reported 2.92K barrels of oil and 580K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
