Water-based drilling fluids are increasingly being used for oil and gas exploration, and are
generally considered to be more environmentally acceptable than oil-based or synthetic …

Water is the sustainable solvent of excellence, but its high polarity limits the solubility of non-
polar compounds. Confinement of water in hydrophobic pores alters its hydrogen bonding …

In this study a series of CH4 adsorption experiments on clay-rich rocks were conducted at
35° C, 50° C and 65° C and at CH4 pressure up to 15MPa under dry conditions. The clay …

In this study, the effects of acid activation with high bentonite contents under mild synthetic
conditions on textural and structural properties were explored. The alteration features after …

The term “clay” was used in everyday language long before being imbued with a well-
defined scientific meaning. Therefore, it is not surprising that it carries different connotations …

Methane (CH 4) adsorption of Ca 2+-montmorillonite (Mt), kaolinite (Kaol) and illite (Il) at 60°
C and pressures up to 18.0 MPa was investigated, during which the adsorption capacity was …

Both natural and anthropogenically-generated hydrogen gas occurs in sedimentary rocks
and geotechnical barriers. Due to high-pressure conditions, a significant portion of H 2 can …

Two of the most common clay minerals, kaolinite and montmorillonite, were allowed to
interact with the cationic dye, Rhodamine B in aqueous solution. The clay minerals were …

The surface reactivity of clay minerals remains challenging to characterize because of a
duality of adsorption surfaces and mechanisms that does not exist in the case of simple …

Key terms and concepts in clay science, which are used in this volume, are introduced in the
present chapter with a focus on the microstructural and surface properties of clay minerals …
