Abstract

Drilling is an activity carried out to achieve the planned target and one of the important supporting materials for drilling is drilling mud. The rheological value of the drilling mud must be in accordance with the conditions of the wellbore. One of the efforts to increase sludge rheology is by adding additive CMC (Carboxymethyl Cellulose) which is useful for increasing viscosity and binding water. The rheological of drilling fluid should be monitored frequently during drilling operations to avoid problems associated with physical changes and drilling breaks into the formation. This research utilizes natural ingredients that are quite a lot in Indonesia, namely jackfruit skin. Jackfruit skin is an underutilized organic waste. Because the jackfruit skin structure contains cellulose, it is very potential to be processed into CMC. Jackfruit skin has a cellulose content of around 50-55%. The stages of making CMC jackfruit skin include Delignification, Alkalization, Carboxymethylation, Neutralization, and Sieve processes. Then added to the drilling mud with the composition of each mud sample of 1 gr, 2 gr, 3 gr, 4 gr, and 5 g to further find the value of viscosity, plastic viscosity, melting point, gel strength, mud cake and filtration volume, pH, and density. Based on tests that have been carried out, the addition of CMC jackfruit skin has an effect on drilling mud rheology. Based on API Spec 13A. (2010) the rheological values that meet the drilling fluid specifications after adding the CMC additive of jackfruit skin are the yield point / plastic viscosity, plastic viscosity, density, and maximum filtrate volume with the addition of 1 to 5 grams of CMC jackfruit skin. While the standard value of gel strength is at a value of 2/3 to 4/5 lb / 100 ft2, or is in a value of 0.67 to 0.8, so that when viewed from the test results, the gel strength value is at the API specification standard value. 13A is in the addition of a sample of 5 grams.
