A colloidal waste material, asphaltite/ shale slime,in salty geothermal drill studies on testing shale slime as a substitute for bentonite in geothermal drll fluids is searched for viscosity and fluidity and coloidal dispersion of drlling mud to be responsible for filtration control in a drilling muddy fluid. There was size a bi distribution condensed in 20 bars of comprssion and filtration . THe slime loss per ton of oily ashaltite material was ess than the bentonite.Furthermore, pressure filtration systems may clog easily if your water is turbid or if other parameters such as iron slime are found in high contents. Some systems provided also waste large quantities of bentonite during the cyclone filtration treatment process that was caused aggragate problem of saline seepage impregnate. It was therefore be better to treat only one oily slime shale with drilling mud with less barite rather than the entire bentonite mud system so that less fluid was wasted.
