Karnes County · Eagleville (Eagle Ford-2) field · Producing · Horizontal
Nichols A Unit #7H (API 42-255-35968) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed February 13, 2019 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued May 25, 2018, permitted to 12,395 ft.
It was permitted by Encana Oil & Gas(USA) Inc. and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Queen City, Reklaw, Carrizo.
Its lease has reported 3.92M barrels of oil and 9.72M mcf of gas since December 2012, last reporting in July 2026. The lease carries 19 wells, so these are lease totals, not this well alone.
