J Avant Las #B 4H (API 42-283-33383) is a horizontal well in La Salle County operated by Ineos USA Oil & Gas LLC, completed July 23, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 13, 2012, permitted to 8,425 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 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.

Its lease has reported 808K barrels of oil and 592K mcf of gas since March 2013, last reporting volume in April 2026. The lease carries 4 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.
