Mallet Land & Cattle CO. F #309W (API 42-079-02259) is a well in Cochran County operated by Texaco E & P Inc., completed July 10, 1943.
The RRC has issued one drilling permit, issued June 25, 2008, permitted to 5,400 ft.
It was permitted by Sandridge Tertiary, LLC and has since transferred to Texaco E & P Inc. on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its 2 leases have reported 925K barrels of oil and 614K mcf of gas since January 1993, last reporting in July 2026. The leases carry 198 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
