Dcr 257 #1 (API 42-131-37842) is a well in Duval County operated by Killam Oil CO. Ltd., completed January 5, 1994 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended 3 times), issued December 14, 1993, permitted to 3,000 ft.
It was permitted by Sonat Exploration CO. - Houston and has since transferred to Killam Oil CO. Ltd. on the wellbore schedule.
Completion filings report 2 formation tops, including Cole, Miranda.
Its lease has reported 59.5K barrels of oil and 7 mcf of gas since March 1994, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
