A Simulink Library for Drilling Modeling, Simulation, and Control

Mitigating drill string vibrations requires detailed and accurate information on downhole parameters. This data is not always available due to slow telemetry systems or a lack of sensors. An advanced drilling model is needed to estimate these parameters and make fast, informed decisions in real time. However, most drilling models used today are recreated multiple times, which requires substantial effort.

In this talk, we will present a prebuilt drilling library created in Simulink^® and walk through a two-degrees-of-freedom drilling dynamics model where the differential equations are modeled in MATLAB^® and Simulink. We will demonstrate how to set up the initial and operating conditions for simulation. Finally, we will inspect and compare data and simulation results to validate and iterate drilling model designs using the Simulation Data Inspector. This way, we can rapidly explore and implement designs without having to design custom libraries in low-level languages.
