THE EFFECT OF CLAYS ON THE PERMEABILITY OF RESERVOIR SANDS TO WATERS OF DIFFERENT SALINE CONTENTS OREN C. BAPTIST AND S. A. SWEENEY U.S. Bureau of Mines ABSTRACT The average results of air- and water-permeability determinations are given for petroleum-reservoir sands, in three Wyoming fields. Permeability and leaching tests were done in the laboratory on clayey ores to evaluate a clay- stabilizing polymer's effectiveness in preventing these problems. Test results indicate that treating the ores with the stabilizer could maintain permeabilities two to five times greater than the long-term permeabilities present in untreated ores.

Permeability is the property or capacity of a porous rock, sediment, or soil for transmitting a fluid; it is a measure of the relative ease of fluid flow under unequal pressure (Bates and Jackson, ).
Clay is a very important material in geotechnical engineering, because it is often observed in geotechnical engineering practice. Generally, this soil type has numerous problems due to its low strength, high compressibility and high level of volumetric changes. Clay needs to be improved before it can be used in road construction, dams, slurry walls, airports and waste : Nazile Ural.

Coefficients of permeability of a N calcium illite. the structure of clay itself possessed a time de- pendent resistance to compression so that the total resistance to volume change came partly from permeability and partly from the structural resist- ance of the clay itself. Actually, prediction of the effect of granule on the permeability is complicated by the fact that solid, less permeable particles are being added to the clay as granule content increases, and may decrease the permeability, as the void ratio of the clay fraction is consistently increased with increasing aggregate content (Shakoor and Cook, ).Cited by:
water had been applied to the permeability tests, hence it was advisable to examine its coagulating effect. The particle size distributions of the clay minerals in the Na- and the Ca-cation adsorption state, observed in distilled and tap water systems, are plotted in figures 2 to*5. Particle Size Distribution Clay Silt Fine sand (Mo) Sand Q Permeability = the capability of clay to permit the FLOW of fluids through its pore spaces. (straight from ) Porosity (generally refers to clay that has been fired) describes how much liquid is ABSORBED. The point is to know how much.

The behavior of unsaturated clayey soil is highly influenced by the coupled interaction between water and clay content. Various aspects of the behavior of artificial clay–sand mixtures with.
