The study on hole cleaning analysis for underbalanced drilling and the impact of inefficient hole cleaning during the drilling operation has been conducted. Inefficient hole cleaning is not pleasing for the drilling operation and hence optimization in hole cleaning has to be achieved in order to increase the overall gross production and saving drilling time The objective of this study to determine the optimum hydraulic parameters for the two-phase nitrogen gasified Newtonian fluids in the horizontal, inclined and near vertical wells for underbalanced drilling using three different methods, which are Beggs and Brill calculation, based on experimental setup and results simulation using Landmark. From the study, Landmark gives results on lowest pressure drop, optimum flow rate and small nozzle size compared to the Beggs and Brill and experimental data. In addition, criteria method A is considered as the most ideal criteria to be used for optimization calculation.
