Continental Resources, Inc. is a petroleum and natural gas exploration and production company headquartered in Oklahoma City.[1] The company was founded by Harold Hamm in 1967 at the age of 21 as Shelly Dean Oil Company, originally named for Hamm's two daughters. In 1990, Shelly Dean re-branded itself as Continental Resources. It primarily used hydraulic fracturing and directional drilling to produce from low permeability formations.
In 1967, Harold Hamm founded Shelly Dean Oil Co., Continental's predecessor.[4]
In 1990, the company was renamed Continental Resources.[5]
In 1995, the company discovered what was later described as the Cedar Hills Field in North Dakota, the 7th largest onshore field in the lower 48 United States ranked by liquid proved reserves, and was the first to develop it exclusively through precision horizontal drilling.[4]
In 2004, the company completed the Robert Heuer 1-17R in Divide County, the 1st commercially successful well in the North Dakota Bakken to be both horizontally drilled and completed using hydraulic fracturing.[7]
In 2008, the company was the first to complete a horizontal well in the Three Forks zone.[9]
In 2010, Continental introduced the ECO-Pad® drilling technique, which involves drilling 4 wells from 1 pad. This reduced the cost of drilling and increased production output.[10]
In 2012, the company moved its headquarters from Enid, Oklahoma to Oklahoma City.[11]
In 2016, the company sold assets in North Dakota and Montana for $222 million.[12][13]
