In the oil and gas industry, drilling is one of the most important aspects due to the economics
and high demand. Reduction in drilling time is required to minimize the cost of operations.
This study focuses on the Polycrystalline Diamond Compact (PDC) drill bit which is
categorized as fixed cutter of drilling bit. Problem such as wear and tear of PDC cutter is one
of the main factors in drilling process failure and this would affect the rate of penetration. Thus,
an intensive study in drill bit design would save a lot of money if the efficiency of drill bit can
be improved. The objective of this project is to finding optimal design of PDC cutter and study
the effect of design improvement to the wear rate. Derive an analytical model of PDC Cutter.
Developing simulation modelling the PDC cutter and to determine the optimal characteristic
of PDC cutter. The analytical model will be developed to collect the required results. Author
will proceed with the simulation modeling using Autodesk Inventor for 3D drawing, which is
based on the results of the analytical model. The modeling varies based on the back rake angle
and the size of cutter. Subsequently, the experiment modeling will be conducted using ANSYS
Explicit Dynamic by certain parameters and constant for the drilling simulation based on the
cutter parameters. After that, the result from the experiment will be analyzed, in which the
optimal characteristic of the cutter is obtained.
