Mallet L&C CO. #29 (API 42-219-10026) is a plugged well in Hockley County, plugged November 30, 2021, last operated by Ctoc Energy LLC.
The RRC has issued one drilling permit, issued May 15, 1985, permitted to 5,080 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Ctoc Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Rustler, Yates, San Andres.
Its 2 leases have reported 1.27M barrels of oil and 1.2M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 85 wells, so these are lease totals, not this well alone.
