Rheology analysis of drilling mud with additive carboxy methyl cellulose from jackfruit’s peel: Experimental study

The value rheology of mud drilling must be under the conditions of hole wells that do not lead to the problems at the time of drilling. One of the efforts to improve the rheology of drilling mud is by adding Carboxymethyl Cellulose (CMC) additive, which helps increase viscosity and binding water. This study utilizes CMC originating from jackfruit skin because it is an underutilized organic waste, and the structure of jackfruit skin contains 50-55 cellulose. Manufacture CMC from jackfruit peel follows serial procedures such as the Delignification, alkalization, carboxymethylation, and sieving processes to obtain a uniform size of CMC powder. Subsequently, plastic-viscosity, yield-point, and gel strength parameters were determined through the Fann VG Meter apparatus and mud cake using a marsh funnel and volume filtration using a filter press. We varied the concentration of CMC additives from 1, 2, 3, 4, and 5 grams. Based on the tests, the addition of jackfruit skin CMC affects the rheology of drilling mud. Increasing additive concentration yields high mud rheology parameters. In addition, the addition of jackfruit skin CMC additives ranges from 1gr – 5 grams meets the API 13 A standard for the value of yield point/viscosity plastic, plastic viscosity, and maximum volume of filtrate. Furthermore, the gel strength value that meets the API 13 A requirement occurs for the sample with 5 grams additive.
