Karnes County · Sugarkane (Austin Chalk) field · SWR-10-Well · Horizontal
Kotara-Ridley Unit #16H (API 42-255-35032) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed March 7, 2017 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued June 15, 2016, permitted to 12,592 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 3 leases have reported 1.88M barrels of oil and 7.84M mcf of gas since March 2016, last reporting in July 2026. The leases carry 15 wells, so these are lease totals, not this well alone.
