The oil and gas industry faces cyclical market conditions that motivate the use of simulation and optimization to reduce costs and decrease exploration and production variability. Physics-based and empirical models have advantages and opportunities for predictive monitoring and control. Current progress, challenges, and opportunities to control critical drilling conditions such as downhole pressure in Managed Pressure Drilling (MPD) are explored. In automated rig systems, there is additional potential to unlock the predictive capabilities of physics-based models to "see" into the near future to optimize and coordinate control actions. A convergence of several key technologies creates an opportunity to use sophisticated mathematical models in drilling. A significant challenge is the size of the physics-based models that have too many adjustable parameters or are too slow in simulation to extract actionable information. This presentation shows how fit-for-purpose models can be used directly in automation and optimization solutions. These fit-for-purpose models have unlocked new ways of thinking. Hybrid modeling uses the strengths of both physics-based and data-informed modeling approaches. A hybrid approach uses a priori knowledge in the form of a nonlinear physics-based model with empirical model elements. The challenges and opportunities for combining physics-based and data-driven elements are discussed. The methods are demonstrated with drilling automation.
