Cockburn Deep Frio Unit NO.1 #143 (API 42-481-34821) is a well in Wharton County operated by White Oak Operating Company LLC, completed April 14, 2016.
The RRC has issued one drilling permit (amended once), issued January 31, 2006, permitted to 7,700 ft.
It was permitted by Kcs Resources, Inc. and has since transferred to White Oak Operating Company LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Miocene (undifferentiated), Frio, Anahuac, Boling Dome - Disposal.
Its 2 leases have reported 182K barrels of oil and 501K mcf of gas since March 2006, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
