Project Description

The objective of this project is to develop and validate—based on simplified physics, statistical learning, and/or mathematical approximations—a portfolio of simplified modeling approaches for geologic CO2 storage in deep saline formations for predicting: (1) Injection well and formation pressure buildup; (2) Lateral and vertical CO2 plume migration; and (3) Brine displacement to overlying formations and to the edges of the plume pressure front within the storage formation. Such computationally-efficient alternatives to conventional numerical simulators can be valuable assets during preliminary CO2 injection project screening, serve as a key element of probabilistic system assessment modeling tools, and assist regulators in quickly evaluating geologic storage projects. Additionally, these approaches will improve existing simplified models in their applicability, performance and cost.

Project Benefits

This project focuses on the simulation of CO2 injection and migration over very large areas. This project is improving our understanding of carbon storage capacity estimation, permanence, and efficiency through the development and validation of a portfolio of simplified modeling approaches to predict the extent of CO2 plume migration, brine movement, and pressure impact for a semi-confined system with vertical layering, contributing to better storage technology thus reducing CO2 emissions to the atmosphere. Specifically, this research is providing project developers with tools to quickly and easily screen candidate storage sites and better identify site-specific monitoring needs.
