Solution Gas Drive in Heavy Oil Reservoirs

Solution gas drive is one of the mechanisms by whichoil can be produced from the reservoirs. Solution gasdrive in heavy oil is well known for its anomalousbehavior that shows better performance taking intoaccount the high viscosity of heavy oil. Heavy oilreservoirs show better performance in terms of lowgas oil ratio and pressure decline rate. Theobjective of this book is to provide answers to twoquestions:- What is the role of micro-bubbles if this type ofbubble exists in solution gas drive in heavy oil?- How do changes in pressure gradient and pressuredecline rate affect gas mobility and oil recovery? The answer of these questions is achieved through asimple analysis of the measured data as well as theirnumerical modeling.
