Kresta #1 (API 42-481-34546) is a plugged well in Wharton County, plugged July 29, 2020, last operated by Cml Exploration LLC.
The RRC has issued 2 drilling permits (amended once) between 2003 and 2004, permitted to 10,000 ft.
It was permitted by Patterson Petroleum LP and has since transferred to Cml Exploration LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Jackson, Top Hockley Sand, Yegua, Ey-5.
Its 3 leases have reported 31.5K barrels of oil and 906K mcf of gas since August 2003, last reporting in November 2023. The leases carry 3 wells, so these are lease totals, not this well alone.
