Polyethylene Polymer Beads on Cuttings Transportation Improvement in Deviated Holes

Abstract
The quest for petroleum exploration and production has been uprising in fulfilling the energy demand. As oil and gas wells are being drilled deeper and in various directions, hole cleaning efficiency is significantly affected. In order to overcome this problem, this study was conducted to investigate the effect of polyethylene beads on water-based mud to increase cuttings lifting efficiency. The experiments were carried out in an 11 ft test section fabricated rig using 10ppg water-based mud and 1% to 5% concentration by volume of low density polyethylene polymer beads. Cuttings transportation performances were studied in three angles of inclination, i.e., 0˚, 60˚ and 90˚. Mud with xanthan gum performed the best under turbulent flow regardless of hole angles. Both types of muds showed positive results on cuttings transportation when polyethylene beads were added. Cuttings transportation performance was thebest in vertical hole while the poorest performance was in 60˚ wellbore. Keywords – Viscosity, low density polyethylene beads, wellbore inclination
