Drilling mud is the most important part in drilling activity. Drilling could work fluently, safely, and economically on fluency by system and condition of drilling mud. It means the mud system and the physical properties of the slurry conform to the required specifications. There are some kinds of drilling mud that can be used in oil and gas drilling operation, such as water base mud and oil base mud. In terms of economical objective, water base mud is usually used in drilling process. The purpose of this study is to conduct laboratory research of the effect of various temperatures on the characteristic of mud system of low solid mud by adding biopolymer and bentonite extender. This research uses roller oven method as a medium for simulation to condition the mud as close as possible to the condition in wellbore to see the change of physical properties of sludge at various temperatures. The result found is that the higher the temperature, the lower the drilling mud physical properties such as density, viscosity, plastic viscosity, yield point, dial reading 600 RPM, dial reading 300 RPM, and gel strength. However, it is found that not all the physical properties decrease.
