Abstract

This research aims to analyze the effect of adding sago starch (Metroxylon sagu) and industrial Carboxymethyl Cellulose (CMC) on the filtration loss of water- based drilling mud. The mud was formulated using bentonite as the base material, with the addition of three types of additives: sago starch only, CMC only, and a combination of both. Each additive was tested at varying concentrations of 3, 5, 7, and 9 grams. The tests were conducted on parameters including filtration loss, mud cake thickness, apparent viscosity, and mud density in accordance with API RP 13B-1 standards.The results showed that CMC was the most effective additive in reducing filtration loss, with the lowest value recorded at 5.6 mL using 9 grams of CMC. Although not as effective as CMC, sago starch was still capable of reducing filtration loss by up to 28.5% and gradually increasing viscosity. The combination of sago starch and CMC at 5 grams yielded a filtration loss of 6.6 mL and a mud cake thickness of 2.3 mm, indicating optimal synergistic performance that is both stable and efficient.Based on the experimental results, it is recommended to use sago starch at concentrations of 3–5 grams per 350 mL of mud to achieve efficient filtration control without producing excessively thick mud cake. Adding more than 5 grams resulted in higher viscosity and thicker mud cake, potentially disrupting mud circulation and reducing drilling efficiency.In conclusion, the combination of natural (sago starch) and synthetic (CMC) additives provides the best technical and economic performance. The use of locally sourced sago starch as an additive offers significant potential in supporting more environmentally friendly and sustainable drilling practices while reducing reliance on imported materials.
