The effect of cuttings transfer means improving the hole cleaning operation in the drilling process, increasing the penetration rate, preventing pipe stuck, and reducing torque and drag problems. If the well is cleaned optimally and promptly, the drilling speed will increase, and the final cost will decrease. The parameters affecting the well cleaning operation are drilling fluid characteristics, drilling cuttings characteristics such as shape and size, bottom hole assembly (BHA) design, drill nozzle characteristics, well deviation degree, drilling fluid volume rate, and drill penetration rate. This study investigates the effect of drilling stabilizers on cleaning and fluid pressure drop. The experimental design output for the laboratory simulator was used to investigate the behavior of the cuttings. In experiments by changing the angle of the simulator, the effect of the well deviation angle in the presence of a drilling stabilizer has been investigated. As the distance of the stabilizer from the laboratory bit increases, the pressure drop decreases. The pressure drop will be less in the laboratory environment with more drill string rotation. As long as the rotation does not increase the friction force and only allows the cuttings to move more easily in the rotation path, hole cleaning will improve, and we will see the bed's movement and height change. As the density of the cuttings increases, the pressure drop increases slightly, and the cutting base height also increases. The optimum place of the stabilizer helps with hole cleaning when placed 75 cm away from the bit.
