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-based drilling fluids (WBDFs), a more environment-friendly candidate than oil-based
are widely used for drilling oil and gas wells. However, wellbore instability due to active clay …

The understanding of the swelling phenomenon of montmorillonite is essential to predict the
physical and chemical behavior of clay-based barriers in geoenvironmental engineering …

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 …

Many countries intend to use compacted bentonite as a barrier in their deep geological
repositories for nuclear waste. In order to describe and predict hydraulic conductivity or …

Shale hydration and swelling are disadvantageous for well drilling, especially when using
water-based drilling fluids. In this work, the ionic liquid 1-vinyl-3-ethylimidazolium bromide …

Nano-particles of bentonite have been prepared by nano-grinding. The nano-bentonite was
characterized by X-ray fluorescence analysis (XRF), X-ray powder diffraction (XRD), thermal …

Molecular dynamic simulations are employed to study the crystalline swelling behavior of
montmorillonites (MMTs) with different interlayer Na+ and Ca 2+ ion compositions, and the …

This paper presents a comprehensive experimental investigation on shrinkage and soil-
water retention behaviour at macroscale and microscale of four natural Australian soils upon …

The osmotic character of long-range interlamellar swelling in smectite clays is widely
accepted and has been evidenced in the interlayer space by X-ray diffraction. Such a …
