HOUSTON, Nov. 13, 2013 /PRNewswire/ — Endeavour International Corporation (NYSE: END) (LSE: ENDV) („Endeavour” or the „Company”) today announced that it has closed on the sale of 50% of its upstream and midstream assets in the Pennsylvania Marcellus and formed a joint venture with Samson Exploration, LLC. 

Samson Exploration, LLC is a wholly-owned subsidiary of privately-held Samson Energy Company, LLC with its headquarters located in Tulsa, Oklahoma. The agreement provides for the development of the Marcellus assets, with a „cash and carry” component.
