Continental Resources Announces 14 Percent Increase in Proved Reserves, Successful Completion of Confirmation Trenton/Black River Wells and Date for Release of Fourth Quarter and Year-End 2007 Results
ENID, Okla.

Continental Resources today announced proved reserves of 134.6 million barrels of crude oil equivalent as of December 31, 2007, a 14 percent increase over the prior year-end. Future net cash flows from the proved reserves, before income taxes, were $6.9 billion with a present value (discounted at 10 percent) of $3.5 billion.


Crude oil reserves were 104.1 million barrels of crude oil (77 percent of the total equivalent proved reserves as of December 31, 2007) and natural gas reserves were 182.8 Bcf. Proved developed reserves represented 75 percent of the total.

Harold Hamm, Chief Executive Officer and Chairman of the Board of Continental Resources, commented, "Proved reserves additions in our relatively new, unconventional resources plays in the North Dakota Bakken and Oklahoma Woodford Shale areas were the principal sources of reserve additions. I expect those two areas to produce significant proved reserve additions in 2008 as well."

Trenton/Black River update

Continental Resource's previously announced Trenton/Black River discovery well in Hillsdale County, Michigan, the McArthur 1-36, is back on production at 260 gross barrels of crude oil per day after the installation of permanent production equipment. Plans are to increase the test rate to 310 gross barrels of crude oil per day in mid February. Continental Resources has estimated gross proved reserves of 824,000 barrels of crude oil equivalent for the discovery well. A second well targeting the Trenton/Black River, the Anspaugh 1-1, has been drilled and produced approximately 500 barrels of crude oil during its initial 10 hour flow period. A third well, the Wessel 1-6, has been drilled and, based upon drilling shows, appears to have encountered the Trenton/Black River formation. Casing has been set on the Wessel 1-6 and completion operations will begin this week. Continental Resources has an 83 percent working interest in each of the three wells. Continental Resources owns leases covering 33,000 net acres prospective for the Trenton/Black River in Hillsdale and surrounding counties in Michigan, and has shot and processed 11 square miles of 3D seismic on the acreage. Continental Resources is currently acquiring permits for an additional five wells and for a 20 square mile 3D seismic acquisition project later this year.

Harold Hamm commented, "The successful completion of these latest wells provides further confirmation that our interpretation and processing techniques used on the 3D seismic are the innovations necessary to properly position wells to encounter the hydrothermal dolomitized reservoir rock."
