Abstract

The cementing process is very important in oil and gas drilling operations, the quality of cement needed in cementing operations must be strong and sturdy so that the casing does not collapse due to pressure from the formation walls. One of the main problems that often occur during cementing is filtration loss and compressive strength. To overcome this problem by using CMC additives because CMC can reduce filtration loss and increase compressive strength, this research uses CMC additives derived from agricultural waste, namely bagasse because the price is more affordable and also environmentally friendly, bagasse has cellulose content so it can be used as CMC material. Then the CMC from the bagasse is added to the cement slurry through analysis in the laboratory with concentrations of 0%, 0.2%, 0.6%, 1%, 1.4%, 1.8%. The results of these tests obtained a concentration of 1.8% the lowest filtration loss value, which with the addition of Industrial CMC 44,880 ml/minute, and bagasse CMC 58,997 ml/minute, for compressive and shearbond strength the concentration of 1.4% was the highest compressive value. CMC Industrial 1988.26 psi, CMC Bagasse 1784.54 psi, while for the value of shearbond strength Industrial CMC 510.44 psi, CMC Sugarcane Bagasse 487.49 psi
