A NEW ECO-FRIENDLY AND LOW COST ADDITIVE IN WATER-BASED DRILLING FLUIDS

This study investigates the possibility of using rice husk ash as an additive to develop an environmentally friendly and low-cost drilling fluid system. Rice husk ash was added as an additive to water-based bentonite drilling fluids at different concentrations ranging from 2 wt% to 15 wt%. The rheol...
