LA Salle County · Briscoe Ranch (Eagleford) field · Producing  · Horizontal

Vesper Dim #A 1H (API 42-283-36356) is a horizontal well in La Salle County operated by Ineos USA Oil & Gas LLC, completed November 12, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 23, 2018, permitted to 9,000 ft.

It was permitted by Chesapeake Operating, L.L.C. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Yegua, Queen City, Sparta, Wilcox.

Its lease has reported 2.87M barrels of oil and 5.81M mcf of gas since May 2011, last reporting in July 2026. The lease carries 17 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
