Analysis the influence of natural non-toxic components on physicochemical parameters of drilling fluids

Objective: to analyze the effect of non-toxic components on physical andchemical characteristics drilling fluids. Methodology: determination (density, plastic viscosity, yield point, effective gel strength, water cut, mud cake thickness), chemical (ph). results: threeиdifferent fluids were prepared, their and studied, a Comparative analysis was carried out, impact marine ecosystem assessed. Conclusions: considered are competitive with others used in well construction terms properties, also less damage environment is expected.
