Steerable Drill Strings, Downhole Tools
Drilling and downhole tools must be designed for maximum reliability. As downhole pressures and temperatures increase — along with drill lengths — tool performance must be optimized for precise positioning and control, designed to operate in more corrosive environments at high pressure and high temperature, and be able to withstand fatigue, vibration and thermal stresses.
Components and subsystems of steerable drill string are designed by ANSYS simulation tools. This includes seals, packers, motors, turbines, threaded connections and electronic components.

Building and testing equipment prototypes is costly and sometimes nearly impossible, making engineering simulation a key capability. Software from ANSYS allows engineers to replicate and study all types of downhole tools, under a variety of real-world conditions, in order to optimize their performance, safety and reliability.
To complement their experimental studies, companies rely on ANSYS to gain engineering productivity and perform integrated analysis of their entire drilling and downhole systems.
