A Review on Cold Heavy Oil Production Technology

Abstract

Abstract: Heavy oil is the important resource of 21st century. Producing heavy oil resource will be the important means to lessen the pressure resulted from crude oil shortage in the future. To economically and efficiently exploit heavy oils is of realistic and strategic meanings to China. Nowadays, the domestic heavy oil reservoirs are mainly exploited by steam injection process, but serious challenges come from sand problem, steam breakthrough and high production cost. The cold heavy oil production (CHOP) technology can be applied to form in-situ high permeable channels by mass sand inflow and allow the heavy oil to be produced by means of foam-oil effects. Field practices abroad indicate that this technology is better than others in terms of decrease of production cost and utilization of crude resources.

Key words: heavy oil, sand inflow, cold production
