La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Shenkir #4H (API 42-283-35073) is a horizontal well in La Salle County operated by Trinity Operating (Usg) LLC, completed February 11, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 5, 2014, permitted to 9,324 ft.
It was permitted by Comstock Oil & Gas, LP and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Escondido, Olmos, Austin Chalk, Eagle Ford.
Its 2 leases have reported 299K barrels of oil and 787K mcf of gas since September 2014, last reporting volume in April 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
