J Tyler Unit I Las #P 4H (API 42-283-34943) is a horizontal well in La Salle County operated by Ineos USA Oil & Gas LLC, completed February 21, 2015 and listed as shut in on the RRC schedule, shut in December 1, 2025.

The RRC has issued one drilling permit, issued July 19, 2014, permitted to 8,448 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 10 formation tops, including Yegua, Queen City, Sparta, Wilcox.

Its lease has reported 716K barrels of oil and 515K mcf of gas since November 2012, last reporting volume in April 2026. The lease carries 3 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.
