W Well VIN is a drilling vertical well with phase of 8 1/2 " drilled from 2097 to 5555 ft. Evaluation of the data needed hudrolika drilling hydraulics and physical properties of the mud like flow rate (Q), mud density (ρ), plastic viscosity (PV), yield point (YP) and data other drilling. The purpose of mud hydraulic is to determine the in the annulus and determine the pressure loss of drilling mud circulation. Pressure loss can change the value of reynolds number and flow rate so flow partern have to be designed to avoid turbulent flow. If turbulent flow was happened, the friction effect will be greater than laminar flow. It is therefore necessary to study the hydraulics planning before drilling is done and then do an analysis to determine whether the efficiency of the hydraulics which has been designed and flow rate that occurred in a series of drilling has been running optimally. Optimization is done by adjusting the amount of pressure on the bit and the flow rate so that the resulting optimum conditions. BHHP optimum or successful if the BHHP at bit is around ± 65 % . The valueBHHP with HPS is 62 % . So bit hydraulics optimization using BHHP is successful.
