OPM Flow is an open-source reservoir simulator that has been under development for over a decade, with the goal of full operational deployment. It supports a broad range of fluid models and advanced well models used in industry, while also offering nonlinear and linear solvers fresh from research. The simulator scales to models with hundreds of millions of cells on HPC systems, and GPU support is currently in development.
As the simulator has matured, the focus has shifted from the initial development of standard flow models towards supporting a wide variety of model options and additional features required for real-world applications, all while minimizing runtime. Other areas of focus included improving error reporting, documentation, and the integration with pre- and post-processing tools to streamline connection with industrial workflows.
Scaling up the simulator has also involved managing a geographically distributed team and balancing diverse stakeholder interests, raising important questions about governance and decision-making processes.
This presentation will explore how OPM Flow has navigated these challenges, highlighting both successful design decisions and instances where unforeseen consequences arose. These lessons offer valuable insights for others working to scale open-source simulators for industrial readiness.
