Abstract

In the petroleum industry, drilling is one of the most important aspects due to economic reason. Reduction in drilling time is required to minimize the cost of operations. This study focused on dynamics study of Polycrystalline Diamond Compact (PDC) drill bit profile and drilling fluid study on affecting the rate of penetration (ROP) and tool ware for single formation. ROP is defined as the speed at which the drill bit penetrates the formation or breaks the rock under it to increase the depth of borehole. The well drilling cost can be lowered when drill bit performing high rate of penetration hence the time of drilling reduced. Drilling fluid also needs to be considered in order to achieve maximum rate of penetration. From time to time, drilling-fluid systems are designed and modified to perform efficiently under those particular conditions due to differences in wellbore conditions. The objective of this project is to investigate the types of bit design features to study the effect of design improvement on the rate of penetration (ROP) and tool wear. The computer software, ANSYS Autodyn/Explicit Dynamics being used in the project to observe the impact of bit profile in presence of drilling fluid to the rate of penetration (ROP) and the tool wear being used.
