Structural Organization of Na- and K-Montmorillonite Suspensions in Response to Osmotic and Thermal Stresses
Montmorillonite SAXS Structure Suspensions Texture
2011/12/8
Abstract: In order to understand the influence of salt concentration and temperature on the behavior and properties of clays used in drilling muds, we studied montmorillonite supensions (4 g clay/100 ...
Clays, Cations, and Geophysical Log Response of Gas-Producing and Nonproducing Zones in the Gammon Shale (Cretaceous), Southwestern North Dakota
Exchange cations Geophysical log Mixed layer Natural gas Shale Statistical analysis
2012/2/6
The Upper Cretaceous Gammon Shale has served as both source bed and reservoir rock for accumulations of natural gas. Gas-producing and nonproducing zones in the Gammon Shale are differentiated on the ...
Abstract: Recognition of the fact that clays exhibit both viscous and elastic response characteristics has led to the use of the theory of viscoelasticity for describing their mechanical behavior. Thi...
