Kolinek #1H
McMullen County · Eagleville (Eagle Ford-1) field · Shut IN · Horizontal
Kolinek #1H (API 42-311-34593) is a horizontal well in Mcmullen County operated by Gulftex Energy LLC, completed September 11, 2011 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued July 11, 2011, permitted to 10,000 ft.
It was permitted by Eog Resources, Inc. and has since transferred to Gulftex Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 382K barrels of oil and 230K mcf of gas since September 2011, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
