Kosmos was founded in 2003 to find oil in under-explored parts of the world. Members of the management team – who had previously worked together making significant discoveries and developing them in Africa, the Gulf of Mexico, and other areas -- established the company on a single geologic concept, the Late Cretaceous play system that previously had been overlooked by others in the industry.
In 2007, the Kosmos team proved the geologic concept worked, discovering the massive Jubilee Field in the deep waters offshore Ghana. Other significant discoveries offshore Ghana soon followed, even as the company pursued new exploration opportunities in other areas along the Atlantic Transform Margin. In 2011, Kosmos became a publicly traded company on the New York Stock Exchange.
