Abstract
Drilling is an activity carried out to achieve the planned targets and drilling mud is a material that is very important if there is a drilling process, so the mud must be considered the value of the rheology of the mud to match the condition of the wellbore. One of the efforts to regulate the rheology of mud can be by using CMC (Carboxymethyl Cellulose) additives which are useful for viscosity and binding of water. This research uses CMC made from organic, namely cassava peels. Cassava peels is an underutilized organic waste. Due to the fibrous structure of cassava peels, it is very potential to be processed into CMC. Cassava peels has a high cellulose content (80-85%), water (9.8%) and ash (6.3%). Making CMC cassava peels by Delignification, Alkalisation, carboxymetilation, Neutralisation, and sieve. Then it is added to the drilling mud with the composition for each mud sample of 1 gr, 2 gr, 3 gr, 4 gr, and 5 g to further find the value of viscosity, plastic viscosity, yield point, gel strength, mud cake and volume of filtration. Based on the tests that have been carried out with the addition of CMC of cassava peels, the rheological values meet the drilling fluid specifications based on API Spec 13A. (2010) is mud with the addition of CMC composition of 3 gr and 4 gr cassava peels with plastic viscosity values of 17 cp and 19 cp, yield point values of 18 lb / 100 ft² and 27 lb / 100 ft², mud cakes of 0.9 mm and 1 mm, and the filtrate volume is 5.5 ml and 5 ml.
