Implementations of a Flexible Framework for Managing Geologic Sequestration Modeling Projects

摘要

Numerical simulation is a standard practice used to support designing, operating, and monitoring CO2 injection projects. Although a variety of computational tools have been developed that support the numerical simulation process, many are single-purpose or platform specific and have a prescribed workflow that may or may not be suitable for a particular project. We are developing an open-source, flexible framework named Velo that provides a knowledge management infrastructure and tools to support modeling and simulation for various types of projects in a number of scientific domains. The Geologic Sequestration Software Suite (GS~3) is a version of this framework with features and tools specifically tailored for geologic sequestration studies. Because of its general nature, GS~3 is being employed in a variety of ways on projects with differing goals. GS~3 is being used to support the Sim-SEQ international model comparison study, by providing a collaborative framework for the modeling teams and providing tools for model comparison. Another customized deployment of GS~3 has been made to support the Class VI Well geologic sequestration permit application process. In this case, GS~3 is being used to manage data in support of conceptual model development and provide documentation and provenance for numerical simulations. An additional customized deployment of GS~3 is being created for use by the United States Environmental Protection Agency (US EPA) Underground Injection Control (UIC) Program to aid in the Class VI Well geologic sequestration permit application review process. These use cases demonstrate GS~3's flexibility, utility, and broad applicability.
