Oil and natural gas production from Whiting’s Pronghorn acreage in Stark and Billings counties, combined with adjacent Stark County acreage owned by Fidelity Exploration & Production Company (an MDU Resources subsidiary), will supply these facilities. Fidelity and Whiting currently have a combined seven rigs operating in the acreage feeding the facilities.“These assets will provide valuable natural gas and crude oil infrastructure for us to capture and process natural gas and allows us to take advantage of more choices to market crude oil,” Hildestad said.
