Chesapeake Energy Corporation and BP America Announce Fayetteville Shale Joint Venture

OKLAHOMA CITY, OK AND HOUSTON, TX, SEPTEMBER 2, 2008 – Chesapeake Energy Corporation (NYSE:CHK) and BP America (NYSE:BP) today announced the execution of a Letter of Intent for a joint venture whereby BP will acquire a 25% interest in Chesapeake’s Fayetteville Shale assets in Arkansas for $1.9 billion.
The assets have current daily net production of approximately 180 million cubic feet of natural gas equivalent and include approximately 540,000 net acres of leasehold which the companies believe could support the drilling of up to 6,700 future horizontal wells. As a result of the transaction, BP will own approximately 135,000 net acres of this leasehold and Chesapeake will own approximately 405,000 net acres.
BP will pay $1.1 billion in cash at closing and will pay a further $800 million during the remainder of 2008 and in 2009 by funding 100% of Chesapeake’s 75% share of drilling and completion expenditures until the $800 million obligation has been funded. Chesapeake plans to continue acquiring leasehold in the Fayetteville Shale play and BP will have the right to a 25% participation in any such additional leasehold. The transaction is subject to the execution of mutually acceptable definitive documentation that the companies anticipate executing within the next week and closing is anticipated to occur later this month.
Aubrey K. McClendon, Chesapeake’s Chief Executive Officer, commented: “We are honored to broaden our business relationship with BP and are excited about the mutually beneficial nature of our transactions with them. Just a month after closing the sale of all our Arkoma Basin Woodford Shale assets in Oklahoma to BP for $1.7 billion, we are pleased to now announce a second major transaction with BP for a 25% interest in our Fayetteville Shale assets in Arkansas for $1.9 billion. We believe this transaction creates substantial value for both companies, highlights the attractiveness and significant value of Chesapeake’s assets and confirms the structural appeal of our innovative joint venture structures.
“The PXP Haynesville Shale joint venture and the BP Fayetteville Shale joint venture together will pay for approximately $2.5 billion of Chesapeake’s drilling and completion expenditures currently planned for the second half of 2008 through 2010. As previously announced, we are also pursuing a similar transaction involving our Marcellus Shale assets with others in the industry that we hope to complete by year-end 2008.”
BP Chief Executive of Exploration and Production Andy Inglis stated: “This transaction, when combined with our recent Woodford acquisition, establishes a material position in the two attractive shale plays in the Arkoma Basin. Together with our substantial position in the emerging Haynesville Shale play in East Texas, BP has made a strategic entry into three top tier shale plays in North America and established potential shale resources of 1 billion barrels oil equivalent net to BP. Development of these resources, along with our leading position in Coal Bed Methane production, and our extensive tight gas plays throughout North America, will enhance BP’s position as a leader in ‘unconventional’ gas technology and enable growth of our North American onshore natural gas production from today’s level of 470 thousand barrels per day oil equivalent. We look forward to working closely with Chesapeake as they develop the significant Fayetteville play.”
