Sand Flat Unit #58 (API 42-423-31142) is a well in Smith County operated by Vess Oil Corporation, completed April 23, 2025 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued January 22, 1988, permitted to 8,400 ft.
It was permitted by Texaco Producing Inc. and has since transferred to Vess Oil Corporation on the wellbore schedule.
Completion filings report 11 formation tops, including Pecan Gap, Austin Chalk, Woodbine, Buda.
Its lease has reported 5.52M barrels of oil and 369K mcf of gas since January 1993, last reporting in July 2026. The lease carries 58 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 645K barrels injected in the 12 months reported through October 2025.
