Pioneer Natural Resources Co., Irving, Tex., wants to sell some leases in eastern Colorado involving 640,000 acres, according to a sales listing with Meagher Energy Advisors in Denver.
The leases PNR offered for sell are in Bent, Cheyenne, Crowley, Elbert, Kiowa, Kit Carson, Lincoln, Prowers, and Washington counties. These leases involve Niobrara shallow oil and gas as well as other formations.
The leases include unconventional potential in the upper Cherokee and middle Atoka shales, the sales listing said. PNR has cored three vertical unconventional test wells. It also drilled two lateral appraisal wells, one each in Cherokee and Atoka, both testing oil to surface.
The leases are expiring during 2016-18, and most have 5-year extension options, the sale listing said.
