Kaufman County · Sunlight (Woodbine) field · Shut IN · Vertical
Clark #1 (API 42-257-00443) is a well in Kaufman County operated by Triton Energy LLC, completed February 19, 1985 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued September 27, 1984, permitted to 3,100 ft.
It was permitted by Sunlight Energy Corp. and has since transferred to Triton Energy LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Nacatoch, Austin Chalk, Subclarksville, Woodbine.
Its lease has reported 29.6K barrels of oil and 19 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
