Ultra-Lightweight Cement Slurry to Seal Wellbore of Poor Wellbore Stability
Energies, 2020 The article presents the recipe for ultra-lightweight cement slurry for wellbore sealing. In ordinary lightweight cement slurries, the addition of microspheres and a large amount of water are used to maintain rheological parameters.

Double-walled carbon nanotube dispersion via surfactant substitution [PDF]
, 2009 A new approach for the stabilisation of double-walled carbon nanotubes in aqueous media was developed. A low molecular weight surfactant was used in the first stage for the debundling of the nanotubes followed by substitution with a higher molecular ...

Stability of the Gunneklev Fjord sediments
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The seabed of the Gunneklev Fjord, with exceptionally soft contaminated sediment, is to be capped. The sediment, containing, among others, mercury and dioxins mixed with natural mud, has an undrained shear strength less than 1 kPa and thickness up to 2.5 m.

Shear-induced sedimentation in yield stress fluids [PDF]
, 2012 Stability of coarse particles against gravity is an important issue in dense suspensions (fresh concrete, foodstuff, etc.). On the one hand, it is known that they are stable at rest when the interstitial paste has a high enough yield stress; on the other
