Title: Experimental Support for a Predictive Osmotic Model of Clay Membranes

Journal Article · · Geochimica et Cosmochimica Acta
OSTI ID:786317

Osmosis has been cited as a mechanism for explaining anomalously high fluid pressures in the subsurface. Clays and shales act as membranes, and osmotic flux across these units may result in pressures sufficiently high to explain these anomalies. The theoretical osmotic pressures as calculated solely from solution properties can be quite large; however, it is not yet resolved whether these geologic membranes are sufficiently ideal to generate such pressures.
