- W2902751504 abstract "Drilling is one the most important processes for the oil and gas industries. Selection of a proper drilling mud is necessary to have an acceptable drilling with the minimum of the cost and maximum of the efficiency. In this research, first, metal nanoparticles of zinc oxide and iron oxide were synthesized and according to initial experiments, zinc oxide nanoparticles were selected to continue the work, then the effects of starch as a biodegradable polymer, zinc oxide as metallic nanoparticles and ultrasonic treatment time as homogenizer were studied on some of the functional properties of water based drilling mud. Experiments were arranged based on central composite design and results were analyzed and optimized using response surface methodology. The optimum of the thermal and electrical conductivity and sedimentation were found at 0.80% starch, 0.80% ZnO and 30 min for ultrasonic treatment. The predicted values were 0.6 (W/mK), 508.91 (µS/cm) and 8.54% for the thermal and electrical conductivity and sedimentation, respectively. Also, to have an optimum drilling mud from the viewpoint of rheological properties, 0.82% starch, 0.20% ZnO and 65.01 min for ultrasonic treatment was found. The predicted values were 45.56 (mPa.s), 0.48, 66.08 (mPa), 3.44 (mPa.s) and 19.43 (mPa/mPa.s) for flow consistency index, flow behavior index, yield point, plastic viscosity and shear-thinning characteristic, respectively." @default.
