Chesapeake Curtails Production for at Least March 2009

Chesapeake has elected to curtail approximately 240 million cubic feet of natural gas equivalent (mmcfe) per day of its gross natural gas and oil production due to currently low wellhead prices in the Mid-Continent region.

The company has curtailed approximately 200 million cubic feet per day of gross natural gas production and approximately 6,000 barrels per day of gross oil production for at least the month of March 2009. The curtailed production represents approximately 7% of Chesapeake's current gross operated production capacity.

Additionally, the company is considering a further 10% reduction in its drilling activity during 2009 if natural gas and oil prices remain low during the next few months. The company's attractive hedges and cash availability provide it with the operational and financial flexibility to curtail production during periods of unusually low prices, such as the current market environment.

The company believes conditions are developing that will support higher prices for natural gas and oil later this year and in 2010.

Aubrey K. McClendon, Chesapeake’s Chief Executive Officer, commented, "We have elected to temporarily curtail approximately 7% of our gross natural gas and oil production in order to protect shareholder and royalty interest owner value during this time of extraordinarily low prices, especially for Mid-Continent natural gas. During March 2009, most Mid-Continent natural gas prices at major interstate pipeline delivery points will average around $2.70 per thousand cubic feet, a price at which most natural gas production is unprofitable. We believe low wellhead prices combined with constrained capital availability will likely cause U.S. drilling activity to decline well beyond the 40% drop already seen since August 2008.

"As a result, U.S. natural gas production will begin to dramatically decline before the end of 2009 and consequently natural gas markets will regain better supply/demand balance by the end of 2009, if not sooner. Our attractive hedges, significant cash availability, approximately $4.0 billion of joint venture drilling carries and high asset quality provide Chesapeake with the strength to curtail a portion of our natural gas and oil production in low price environments. In addition, we have reduced our drilling activity from 158 operated rigs in August 2008 to 110 currently. We are considering a further 10% reduction in our drilling activity, which if implemented, will be in areas where we do not have joint venture drilling carries."
