Project Description

The goal of this research was to identify means of improving CO2 storage efficiency and plume distribution for varying degrees of heterogeneity in geologic reservoirs of different depositional environments identified by DOE as promising storage formations. The approach to achieving this goal included: 1) completing a preliminary screening of Illinois Basin (ILB) geologic formations that represent a broad and diverse portfolio of promising geologic depositional environments for CO2 storage; 2) developing geologic models of ILB geologic formations that are suitable to represent the desired depositional environments and formation classes; 3) using the models to determine baseline estimates of storage efficiency for each of the formation classes; and 4) determining the potential incremental improvements in storage efficiency that could be realized for each of the formation classes by applying various field methods or operational techniques.

Project Benefits

The project improved the overall understanding of carbon storage capacity estimation, contributing to better storage technology thus reducing CO2 emissions to the atmosphere. Specifically, the project used rigorously developed geologic and reservoir models representing different potential formation classes; the models were generalized for use in sedimentary basins throughout North America.
