Abstract

Drilling operation is considered as the most vital aspect in oil economics. It plays a major role in oil and gas industry where it involves time and cost of the operation. Reducing drilling time would be an advantage to the industry as it would result in lower drilling cost. However, there is a major challenge that affect the drilling operation which is the vibrational dysfunctions especially the stick and slip. The stick and slip is known for affecting the whole drilling operation by damaging the bit which reduce the bit life resulting in higher drilling cost and prolong the drilling time. Thus, this research focuses on the design optimization and analysis for the Polycrystalline Diamond Compact(PDC) drill bit in mitigating the stick and slip effects. This intensive study in PDC drill bit design would addressed solutions in combating the problems in which it could lead to time saving and cost effective in drilling operation. The objective of this project is to reduce the stick and slip problem by analyzing various bit design through Finite Element Analysis(FEA) and study the effect of design parameters in mitigating the stick and slip. The optimization of the drill bit is mostly focused on bit design parameters which are the back rake angle, cutter diameter, number of blades and cutter density. Reverse Engineering method will be used in this research to obtain the blueprint of the drill bit due to the unavailability of its blueprint. This method will be done through the laser scanning of the bit to obtain the cloud point of data that is later converted to 3D CAD model.
