N-Solv™ is a patented in-situ technology that uses warm solvent to extract bitumen from oil sands efficiently, sustainably, and economically. Currently, N-Solv™ is preparing to demonstrate the commercial readiness of the technology at its field pilot plant located near Ft. McMurray, Alberta, scheduled to start production in May 2013.
