Review of Physical Properties of Oil Well Drilling Mud

Drilling mud which has long been used in Iran's drilling operations is a mixture of water and other materials to facilitate the drilling operations. This process has, over time, seen various materials of different physical and chemicals added to it. The present study reviews the physical properties of oil well drilling muds. For this, the PHB polymer mud is first made, and nanoparticles are then added to it to examine its properties. Findings suggest that polymer particles improve the rheological properties of drilling mud, increasing its shear stress, viscosity, and yield point.
