The virtual prototyping is leveraged for predicting the vibrations and string dynamics ahead of time, allowing engineers to understand the impact of design changes and avoid many common problems. As Harvey puts it, “With a rich expertise in simulation, our team develops drilling models to efficiently account for the complex non-linear dynamics that include 3D coupled physics, wellbore geometry, geology, controls and fluid systems.” The simulation technology is based on Multi-Body Dynamics (MBD) while incorporating the effects of various sub systems and environmental considerations to capture the overall system level behavior of the drill string while remaining very computationally efficient. The uniqueness of this simulation technology is that it not only models full drill string dynamics but also is fast enough to explore the unknowns and conduct parameter sensitivity studies through design studies and other optimization methods.
The simulation data collected in the process contains crucial vibration and dynamics information, allows an operator to analyze and compare the change in system behavior under different scenarios. These scenarios are modeled using MSC ADAMS (Automated Dynamic Analysis of Mechanical Systems) and any repetitive modeling processes and workflows can be managed and automated with MSC’s simulation data management software, SimManager, making simulation operations more productive, timely, and effective.
We prototype the system, understand its behavior that drives informed engineering decisions while changing designs to reduce vibrations for a better drill string control
MSC Software is assisting Pioneer Natural Resources, a US independent operator, who is looking to study how changes to their well design can impact drilling operations. The application allows them to vary drill string components, operating parameters, wellbore geometry, lithology, and control systems to understand their effect on drill string dynamics. Harvey recalls how MSC Software assisted another large oil and gas company that was looking to reduce a common drilling dysfunction. MSC Software’s simulation model helped research engineers understand the effect of control systems on the drill string dynamics to avoid dynamic dysfunction and mitigate the vibrations in order to drill more efficiently. “They witnessed our unique ability to capture highly non-linear dynamics and evaluate different scenarios to mitigate those vibrations and dysfunctions,” states Harvey.
Looking ahead, MSC Software intends to continue to apply leading technology from automotive and aerospace industries to further enhance the fidelity and speed of drilling simulations. A lot can be learned from our developments in autonomous vehicles and manufacturing, both of which closely parallel industry wide drilling initiatives. “Our strategy is to capture the real-world behaviors with simulation and enable engineers to make sound design and operational decisions that improve the drilling process, reduce risk of failures, and increase production opportunity,” Harvey concludes.
