La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Salinas Unit IV Las #B 4H (API 42-283-33185) is a horizontal well in La Salle County operated by Ineos USA Oil & Gas LLC, completed June 12, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 27, 2012, permitted to 8,165 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Anacacho, Ausitn Chalk, Austin Chalk, Eagle Ford.
Its lease has reported 199K barrels of oil and 128K mcf of gas since January 2013, last reporting volume in August 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
