Cockburn H. C. #145 (API 42-481-34829) is a well in Wharton County operated by Milagro Exploration LLC, completed April 29, 2010.
The RRC has issued one drilling permit, issued February 24, 2006, permitted to 7,700 ft.
It was permitted by Kcs Resources, Inc. and has since transferred to Milagro Exploration LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Miocene (undifferentiated), Het, Frio.
Its 2 leases have reported 450K barrels of oil and 696K mcf of gas since June 2006, last reporting in July 2026. The leases carry 22 wells, so these are lease totals, not this well alone.
