1.1 INTRODUCTION

To meet the growing demands and constraints on energy resources,
oil operators have to exploit more complex reservoirs; but, to do so
requires more advanced technologies. Several recently improved techniques
and technologies are now commercially applied to increase production and
ultimate recovery from both conventional and unconventional resources
(Lake et al., 2014). In low-oil-price markets and competitive environments,
it is particularly desirable to improve the efficiency of improved oil recovery
(IOR) techniques by minimizing any potential risks and costs.
