Abstract

See full text

A method of transporting carbon dioxide and crude oil in a pipeline is disclosed. The method includes providing supercritical carbon dioxide and heavy or extra heavy crude oil produced from a subterranean reservoir. The crude oil is mixed with the supercritical carbon dioxide to form a mixture having a viscosity less than the viscosity of the crude oil prior to mixing. The mixture is transported in a pipeline from a first location to a second location. The pipeline is maintained at sufficient pressures and temperatures such that any unsaturated carbon dioxide remains in a supercritical state while the mixture is transported through the pipeline.
