Canadian company Sherritt International Corporation, the largest direct investor in Cuba, currently extracts about a third of the oil produced by this island, according to company president and CEO David Pathe.

It also generates 15 percent of the energy available on the grid through Energas S.A., a tripartite enterprise integrated by Sherritt, the Cuba-Petroleum Union (Cupet) and the Electricity Union, Pathe said in a press interview.
