dc.description.abstract | A critical salt concentration (CSC) was found to exist in the water sensitivity of Berea sandstone. If the salinity of the permeating fluid falls below the CSC, the sandstone permeability is significantly reduced as a result of clay particles being released from the pore walls and blocking the pore throats. However, when changes in salinity occur above this threshold value, clay particles are not released from the pore walls in the sandstone and therefore no reduction in core permeability occurs. The CSC was determined by core flood experiments in conjunction with particle analysis of core effluent samples. The CSC exists only in the case of monovalent cations and is virtually nonexistent for cations having a valence greater than one. Even among monovalent cations the CSC varies considerably and it decreases with increasing ion exchange affinity of the clay for the counterion. For polyvalent counterions, the release of clay particles is effectively prevented due to the strong ion-exchange affinity of clay for the counterion. The critical salt concentration was also found to depend on the temperature, but not on the flowrate, of the electrolyte solution. The temperature dependence has been explained by using the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory of stability of colloidal dispersions. | en_US |
