Sprencel a Unit #1H
Karnes County · Eagleville (Eagle Ford-2) field · Horizontal
Sprencel A Unit #1H (API 42-255-31953) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed January 26, 2012.
The RRC has issued 2 drilling permits between 2011 and 2019, permitted to 13,700 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 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its 2 leases have reported 821K barrels of oil and 3.23M mcf of gas since September 2011, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
