Drilling mud performances consist of CMC made by carton waste and Na2CO3 for reducing lost circulation

Abstract

The Drilling process has the most important main objective is to reach the reservoir zone safely, quickly, and economically. The important component in the drilling process is drilling fluid commonly called by drilling mud. The drilling mud design needs to be properly planned to avoid problems during drilling. The research was conducted for testing the drilling mud rheology by using CMC from carton waste with the addition of Na2CO3, this research was conducted with several scenarios, which in each scenario have different levels of CMC and Na2CO3, from each result can be seen the value of density, viscosity, mud cake, pH, and filtrate volume of each sample. Thus it can be seen the best mud performance from the addition of CMC waste carton waste and Na2CO3 to the drilling mud. The results of this research is the addition of CMC waste carton and Na2CO3 in the dominant drilling mud to rheology and aditive function of CMC in increasing the viscosity were in 5 gr sample with 4.5 gr of Na2CO3 addition, with density value: 8.75 ppg, viscosity: 26 cp, mud cake: 0.54 cm, pH: 12, and filtrate volume: 4.42 ml.
