...Materials and Methods The non-aqueous suspension comprises a carrier fluid, which contains organic or BETX-free solvents, such as Solvent A, B, and C. Solvent A is glycol based, while Solvent B is polyol based and Solvent C contains mineral oil. Along with the carrier fluid, other additives...

... namely Zizyphus Spina-Christi and used for preparation of aphron-based fluids. To evaluate the potential use of new plant-derived surfactant as an aphronizer, various physico-chemical properties of aphron-laden muds were investigated. To achieve the research objectives, laboratory tests of suspension...

..., bridging agent, suspension dispersing agent, retardant and drag reducer. By adjusting the different proportions of components to make sure the density of this new blocking agent is in 1.00~1.10g/cm 3 between oil (0.80~0.98g/cm 3 ) and water (1.14g/cm 3 ) which can build up packer existing in water-oil...

... shearing speed can be used as an enhancement method to improve the dispersion rate of the clay suspension, and hence increase viscosity and decrease filtration loss. But the used shearing speed should be limited to a practical and economical speed. The bentonite extender can be either a salt or a polymer...
