... density and is lower than condensate ( Vayenas et al, 2002 ). This implies that injecting CO 2 increases the density of the gas and decreases the density of condensate. Consequently, this lowers the surface tension according to equation (3) . Condensate viscosity reduction Compositional...

... mobility are used to modify the well trajectory. NMR while drilling is applied for placement of power-water injection wells to detect zones bearing heavy immobile oil where the ability to inject is unlikely. Algorithms were developed to estimate the in-situ oil viscosity. Moreover, neural-network models...

... + H 2 O The produced calcium chloride and the increase in pH value will transform the special micellars into long rod-shaped ones. This transformation is accompanied by significant increase in fluid viscosity. It is very important to measure the effect of Ferric ions (Fe3...
