Duval Ranch -59- #28 (API 42-131-34795) is a well in Duval County operated by Killam Oil CO. Ltd., completed May 27, 2020 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued March 18, 1980, permitted to 2,300 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Killam Oil CO. Ltd. on the wellbore schedule.
Completion filings report 4 formation tops, including Cole, Cole Sand, Gov'T Wells, Govt. Wells.
Its lease has reported 798K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 21 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 300K barrels injected in the 12 months reported through November 2025.
