Squeezing, pore-fluids

Squeezing of pore-fluids from geological materials is a fundamentally simple technique, analogous to natural consolidation although at a greatly accelerated rate. [Pg.266]

Upon moving from the pore constriction (f=0) to the pore body (f = A/2), the lamella is stretched as it conforms to the wall. To achieve the requisite volume rearrangement a radial pressure differential is induced which thins the film but results in no net fluid efflux into the Plateau borders. The converse occurs when the film is squeezed upon moving from a pore body to a pore constriction. If R /R, or equivalently a, is large enough... [Pg.467]

In the previous section, it was noted that the microscopic displacement efficiency is largely a function of interfacial forces acting between the oil, rock, and displacing fluid. If the interfacial tension between the trapped oil and the displacing fluid could be lowered to 10 to 10 dyn/cm, the oil droplets could be deformed and could squeeze through the pore constrictions. A miscible process is one in which the interfacial tension is zero that is, the displacing fluid and the residual oil mix to form one phase. If the interfacial tension is zero, then the capillary number Nyc becomes infinite and the microscopic displacement efficiency is maximized. [Pg.94]
