Force Prediction and Optimization of Novel Directional Drilling Tool
Client was working on a novel tool used for directional drilling and was able to successfully create a proof of concept through in-house, small scale experiments. However, for the tool to become competitive, further improvements needed to be made many in increasing the lateral force created on the drill string.
The first step of the project was to replicate the initial experiments by simulation and validate the computational methods. This provided insight in the flow mechanisms that generate the forces and that allowed for specific changes to the design to optimize the performance.
The second step was to simulate the newly proposed design changes and predict the performance of the tool. Several designs were explored considering not only the geometry of the tool but also varying flow conditions used. This enabled the design of a high performing and all-rounded tool.
Using the result of this project, the Client was able to finalize the design of the tool and was able to market the new tool as a competitive alternative to existing directional drilling tools.
