Chesapeake Energy Forms 2.2 Million Acre Coal Bed Methane Joint Venture In Oklahoma's Arkoma Basin

Chesapeake Energy Corporation , today announced the formation of a joint venture with one of North America's largest diversified natural gas companies to develop coal bed methane (CBM) reserves from a 2.2 million acre area in eastern Oklahoma's Arkoma Basin. In the initial phase of the joint venture, Chesapeake's partner has paid 100% of the JV's costs for a 75% interest in the JV's assets with Chesapeake owning the remaining 25%. In the secondary phase, Chesapeake will have the option to increase its ownership in the JV to 33.3%. Approximately $10 million has been expended in the JV to date and an additional $10-20 million of investment is scheduled for the next 18 months. Drilling and production activities should begin in the third quarter of 2000.

Management Comment

Aubrey K. McClendon, Chesapeake's Chief Executive Officer commented, "We are very pleased to initiate activities in our new Arkoma Basin CBM play. For many decades the Arkoma Basin in eastern Oklahoma has produced significant reserves of both natural gas and coal. We believe the combination of Chesapeake's land skills and large existing base of Arkoma assets provides a perfect complement to our partner's operational and geological expertise in developing large-scale CBM projects.

"We also believe the Arkoma's combination of strong gas prices and low operating costs will help make the economics of this project compare favorably to other CBM plays in the U.S. In particular, the wells can be drilled, completed and then immediately put in production -- they will not need a lengthy, expensive and environmentally risky de-watering process. We believe all of the elements are in place for our JV to develop a large and successful CBM project in the years ahead."
