Mallet Land & Cattle CO. #11 (API 42-079-00233) is a well in Cochran County operated by Three Span Oil & Gas Inc., completed March 17, 1988 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued September 2, 1987, permitted to 5,100 ft.
It was permitted by Tenneco Oil CO. and has since transferred to Three Span Oil & Gas Inc. on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 940K barrels of oil and 355K mcf of gas since January 1993, last reporting in July 2026. The lease carries 28 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 43.5K barrels injected in the 12 months reported through December 2025.
