Tyler State Park C #C 4 (API 42-423-31579) is a well in Smith County operated by Vess Oil Corporation, completed September 4, 2002 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 22, 2002, permitted to 7,500 ft.
It was permitted by Key Production Company, Inc. and has since transferred to Vess Oil Corporation on the wellbore schedule.
Completion filings report 3 formation tops, including Woodbine, Goodland, Paluxy.
Its lease has reported 1.19M barrels of oil and 39 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.
