. Beginning in February 2013, Nexen took accountability for managing approximately $8 billion in

assets located throughout North and Central America.

Long Lake

The Long Lake project in the Athabasca Oil Sands was initiated in 2001, as a 50/50 partnership between Nexen and OPTI Canada. It was started in order to develop the Long Lake site using steam-assisted gravity drainage and OPTI's OrCrude process for on-site upgrading. Production capacity at Long Lake was estimated of bitumen per day which could be upgraded to of synthetic crude. The proved reserves at the Long Lake site are 310,000,000 bbls. In 2017, the site produced approximately of bitumen. The Long Lake site has had a troubled history, including OPTI's near-bankruptcy in 2011 (with Nexen growing its ownership stake to 65% and eventually 100%), a significant oil spill in 2015, and an explosion in 2016 that resulted in two deaths and the permanent shutdown of the
