Polymer Flooding: Predicting Permafrost Stability For The WSak And Ugnu Alaska North Slope Reservoirs
The heavy oil reserves of the Ugnu and West Sak Formations in Alaska offer major production challenges, including proximity to the permafrost layer and exceptionally high viscosities. Despite deeper reserves, most of the untouched heavy oil deposits in the West Sak and Ugnu sands are at shallow dept...
