Optimizing Drill Bit Design Iteration with a New Sensor System Developed for Large-Scale Deployment and Automated Analysis of Drilling Dysfunctions

A drill bit dynamics sensor system has been developed with a new approach that enables economical, widespread use of downhole data to improve bit design. The system emphasizes ease of deployment and minimal manpower requirements for data interpretation. The goal was to develop a system appropriate for deployment on a new scale to the bit industry. The system consists of a small in-bit sensor coupled with an automated software system that provides direct design guidance targeted at drill bit specialists. This paper aims to detail the design considerations used to develop this system and provide an example application of the technology from field testing.
