Abstract
The type of drilling mud selected has a great role to play in the success of any rotary drilling process. The main function of drilling mud is to remove cuttings during the drilling process. Viscosity is the most needed property of the drilling mud that helps it to perform its task. This property helps the mud to be effective in well cleaning and also assist in suspending drilling cuttings in the hole when circulation of the fluid is put on hold. Monitoring and continuously adjusting the viscosity of the drilling fluid is important. Rheological tests were conducted to determine the plastic viscosity, yield point, gel strength among others. This will help to develop concise understanding to be able to modify these fluids to suit varying conditions that may be encountered during operations for better drilling practices. Results from this investigation showed that, increasing the wellbore flow rate would increase the Cutting Carrying Index. Oil Based Mud samples with higher viscosities tend to have more gel strengths and can also have a good hole cleaning efficiency at an average flow rate.
