Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On October 30, 2018, we jointly announced with WildHorse Resource Development Corporation (“WildHorse”) that we have entered into a definitive agreement to acquire WildHorse, an oil and gas company with operations in the Eagle Ford Shale and Austin Chalk formations in southeast Texas, in a transaction valued at approximately $3.977 billion, including the value of WildHorse’s net debt of $930 million as of June 30, 2018. At the election of each WildHorse common shareholder, the consideration will consist of either 5.989 shares of Chesapeake common stock or a combination of 5.336 shares of Chesapeake common stock and $3.00 in cash for each share of WildHorse common stock. We intend to fund the cash portion of the consideration through borrowings under our revolving credit facility. The transaction has been unanimously approved by the Board of Directors of each company and is subject to shareholder approvals from both companies and customary closing conditions and regulatory approvals and is expected to close in the first half of 2019. On October 29, 2018, we completed the sale of our Utica Shale assets in Ohio to Encino, pursuant to which Encino purchased all of our approximately 1,500,000 gross (900,000 net) acres in Ohio, of which approximately 320,000 net acres are prospective for the Utica Shale with approximately 920 producing wells, along with related property and equipment (collectively, the “Designated Properties”) for net proceeds of $1.868 billion in cash. On October 29, 2018, we delivered a notice of redemption to the trustee for our 8.00% Senior Secured Second Lien Notes due 2022 to call for redemption $1.416 billion aggregate principal amount of the outstanding notes, representing 100% of the aggregate principal amount of the outstanding notes. The notes will be redeemed at a redemption price of 100% of the principal amount thereof, plus the make-whole premium, as calculated in accordance with the indenture, plus accrued and unpaid interest. The settlement of the redemption is expected to occur approximately 30 days from the notice delivery date. The redemption is expected to be funded with proceeds from the sale of our Utica assets in Ohio.
