Solution Gas Drive in Heavy Oil Reservoirs

Solution gas drive is one of the mechanisms by which
oil can be produced from the reservoirs. Solution gas
drive in heavy oil is well known for its anomalous
behavior that shows better performance taking into
account the high viscosity of heavy oil. Heavy oil
reservoirs show better performance in terms of low
gas oil ratio and pressure decline rate. The
objective of this book is to provide answers to two
questions:

• What is the role of micro-bubbles if this type of
  bubble exists in solution gas drive in heavy oil?

• How do changes in pressure gradient and pressure
  decline rate affect gas mobility and oil recovery?

  The answer of these questions is achieved through a
  simple analysis of the measured data as well as their
  numerical modeling.
