ABSTRACT
Water invariably occurs in petroleum reservoirs where petroleum reservoir fluids are found associated with water, occupying the same or adjacent pores.1 With increasing depth, water is also present in an underlying zone beneath the hydrocarbon zones.2 The water present in petroleum reservoirs is commonly referred to as connate water, interstitial water, formation water, oil field water, reservoir water, and sometimes simply brine given the presence of dissolved salts. These terms are used interchangeably in petroleum literature.
