Continental Resources Inc

We are an independent crude oil and natural gas company with properties in the North, South and East regions of the United States. The North region consists of properties north of Kansas and west of the Mississippi River and includes North Dakota Bakken, Montana Bakken, and the Red River units. The South region includes all properties south of Nebraska and west of the Mississippi River including various plays in the SCOOP (South Central Oklahoma Oil Province), STACK (Sooner Trend Anadarko Canadian Kingfisher), and Arkoma Woodford areas of Oklahoma. Historically, our properties in Blaine, Dewey and Custer counties of Oklahoma that produced from the Woodford formation were referred to as the Northwest Cana district, while properties often underlying the same surface acreage in those counties that produced from the Meramec and Osage formations were referred to as the STACK district. Such properties were historically combined by us and referred to as "Northwest Cana/STACK". Effective December 31, 2016, we now refer to such properties simply as "STACK". The East region is comprised of undeveloped leasehold acreage east of the Mississippi River with no current drilling or production operations.
