Characterisation of Geomechanical Properties of

Compressed bentonite in the form of pellets or plugs is used for the abandonment of production wells for the oil and gas industry. The design of the abandonment systems is based on the hydro-mechanical behaviour of the compressed bentonite defined by mechanical parameters that are used from published data rather than quantified for the used material by laboratory investigations.

Properties | Bentonite

Conversely, calcium bentonite, with calcium cation prevalence (Ca2+), while getting hydrated in much the same way, due to its strong positive charge, has lower absorption properties, not permitting water to penetrate through the platelets. In this latter case, platelets flake off rather than swell.
