The main idea was to make stable dispersions with bentonite and sepiolite by using a water soluble polymer as a stabilizer.
The results of pull out test indicate that pull out capacity is reduced by using bentonite or polymer in the boring fluid for stabilization of bore holes, but the reduction is more in case of bentonite than the polymer.
Release kinetics in soil have showed that the control of release rate of chloridazon and metribuzin was possible by using bentonite and anthracite in CRFs, being this effect greater when we use anthracite as modifying sorbent.
Rheological properties of aqueous WHB solutions were compared to hydrocolloid systems prepared by using sodium bentonite, Xanthan Gum, and cellulosic biopolymer (CMC), which are some of the most common additives used for formulating drilling fluids in the oil and gas industry.
Filtration loss properties of aqueous WHB solutions were compared to hydrocolloid systems prepared by using sodium bentonite, Xanthan Gum, and cellulosic biopolymer (CMC), which are some of the most common additives used for formulating drilling fluids in the oil and gas industry.
Physical modelling of pile is done to find out the uplift capacity of bored pile, for that modelled pile is bored without use of drilling fluid and by using different % of bentonite and different % of polymer separately and pull out test is performed on the fabricated test set up.
Adsorption of the dye was studied by batch technique and it was observed that >90%% of dye removal was achieved by using 0.05 g of bentonite.
The improvement of the soil to obtain better conductivity by using conducting salts and bentonite clay is also covered by the chapter.
Hydroxy-iron aluminum pillared bentonite (Hydroxy-iron aluminumsized with ion exchange method, and its catalyst characteristics were analyzed by using X-ray diffraction (XRD) and X-ray pillaredctron spectrometry (XPS).
By using literature data on the in-diffusion of traces of radioactive cesium in an argillaceous rock (Opalinus clay) and a compacted bentonite (FEBEX bentonite), we have demonstrated that taking into account the mass-transfer limitations considerably improves the quality of the theoretical fit of the time evolution of radio-tracer concentration in the reservoir.
