Electrokinetics is a term applied to a group of physicochemicalphenomena involving the transport of charges, action of chargedparticles, effects of applied electric potential and fluidtransport in various porous media to allow for a desired migrationor flow to be achieved. These phenomena include electrokinetics,electroosmosis, ion migration, electrophoresis, streaming potentialand electroviscosity. These phenomena are closely related and allcontribute to the transport and migration of different ionicspecies and chemicals in porous media. The physicochemical andelectrochemical properties of a porous medium and the pore fluid,and the magnitudes of the applied electrical potential all impactthe direction and velocity of the fluid flow. Also, an electricalpotential is generated upon the forced passage of fluid carryingcharged particles through a porous medium.
The use of electrokinetics in the field of petroleum andenvironmental engineering was groundbreaking when George Chilingarpioneered its use decades ago, but it has only been in recent yearsthat its full potential has been studied. This is the firstvolume of its kind ever written, offering the petroleum orenvironmental engineer a practical "how to" book onusing electrokinetics for more efficient and better oil recoveryand recovery from difficult reservoirs.This groundbreaking volume is a must-have for any petroleumengineer working in the field, and for students and faculty inpetroleum engineering departments worldwide.
