Abstract

Drilling mud is a drilling fluid used during the drilling process. One problem that often occurs during drilling operations is filtration loss. Filtration loss that is too large has a bad effect on the formation and the mud itself, because it can cause formation damage (reduction of effective permeability to oil / gas) and mud will lose a lot of liquid. To overcome filtration loss, industrial CMC additives can be used. Due to the CMC additive which is relatively expensive so this study used an alternative material, namely pineapple leaves. Pineapple leaves contain 69.5-71.5% cellulose fiber which has the potential to be used as raw material for making carboxymethyl cellulose (CMC). From the results of rheology research using CMC Pineapple Leaves obtained the value of plastic viscosity with a mass of 2gr-10gr with a range of values ​​of 2-3 cp and yield point with a mass of 2gr-10gr obtained a range of values ​​of 1-3 lb / 100ft2, while the value of gel strength with a mass of 2gr-10gr obtained a value of 1 lb / 100 ft2 . The more addition of CMC, the greater the value obtained. Research on CMC samples of Pineapple Leaves obtained the volume of filtrate in filtration loss with a mass of 2gr-10gr to get results with a range of values ​​of 9-7 ml. The more mass increase of CMC Pineapple Leaves, the value of the volume of the filtrate obtained from the filtration loss will be reduced because the mud is thicker.
