摘要：

The solution gas drive in heavy oil reservoirs was analyzed from the examination of field data by using pseudo-single phase model. Experiment was conducted at a pressure decline rate of 20 psi/day for a heavy crude in single phase. Nonequilibrium phenomena was safely neglected at field conditions in the measurements. Viscosity measured from buildup analysis was of the order of 1-5 poise, whereas viscosity of the same oil was 17-35 poise in single phase.
