Oil and gas drilling is an activity designed to bring oil and gas resources into the surface of the earth using drilling rig. One of the characteristics of drilling wells is HPHT (High-Pressure High Temperature) condition, where this type of well can reach temperature of 150 °C and pressure of 15,000 psi. Due to these extreme conditions, the drilling rig installation often need to be serviced after it operates under HPHT condition before it can be operated again. The influences of HPHT wells conditions to the equipment component in the drilling operation systems are studied to find out the probable failures root cause that make the drilling rig break down and have significant Non-Productive Time (NPT) after operated on HPHT well. During this study, we found out that the root cause of the problem is failed to apply a detailed requirements in SOP and Operation Manual as a provision of drilling operation. The problems become more significant for the rig performance and its NPT thus affecting the overall drilling program and company revenue.
