Good formulations of drilling fluid properties are required in drilling operations. Selection of suitable drilling fluid additives are important criterion in formulating drilling fluid. Investigation on  rheological and viscosity, mud weight, sand content, fluid loss properties of water based drilling mud containing barite, cmc, flyash, starch is presented 3%, 5%, and 8% used, aiming at improving  performance as a fluid loss agent under extreme drilling.
