The research purpose is to study the performant of the rheology and the filtration loss of water-based drilling fluid with 1, 3 and 5% weight per volume (w/v) of sugarcane bagasse (SCB) at 30, 60, and 80 °C according to API RP13B-1. The drilling fluid with SCB showed pseudoplastic flow as the power-law model, increasing on SCB concentration but reducing on the temperature. The viscosity results in the increase of yield point and gel strength as rising of concentration and temperature. The filtration loss of drilling fluid with 3 and 5% SCB at 80 °C reduces as respectively 37.8 to 39.6% that is better than water-based drilling fluid. Therefore, the SCB is suitable to use as an additive for improving the rheology and filtration loss control in drilling fluid ascending order 5%>3%>1% of SCB, resulting from the roughness surfaces and small porous of cellulose, and tobermorite (Ca5Si6O16(OH)2·4H2O).
