Hydraulic Evaluation on 17 ½ inch Hole in Directional Well Y-1, Field Y Using BHHP Method

The evaluation of hydraulics carried out in a trajectory namely 17 ½ inches provides an overview the hydraulic problems that occur with less-than-optimal pressure bit because it is less than minimum percentage value should be. which 50%. affected by factors such as flow rate. mud weight. rheology used and loss both surface sub-surface bit. pipe annulus. So, optimization BHHP (Bit Hydraulic Horse Power) method becomes next step to be taken order for drilling operation can perform better. It has been found from results CTR (Cutting Transport Ratio) cutting analysis demonstrates correct performance transport process if 50% or higher met. In addition, this also takes angle inclination directional well Y-1 into one considerations. On first trajectory. inch hole (1338.58 – 3166.01 ft) increased around 22.83% 31.14% at initial condition 56.20% until 56.59% after being optimized up 99%. use optimize said successful produces greater standard Furthermore, analyze cuttings running showing have successfully transported surface. Therefore, acquisition above
