“…Several modeling studies have been based on the Sleipner injection site, with modeling approaches ranging from coupled multiprocess models to invasion percolation models and VE models. Simplified 3D multiphase models were used for injectivity and capacity estimates (Baklid et al ; Zweigel et al ) and to show that the existence of thin mudstone baffles can explain the vertical plume structuring found from the seismic surveys (Lindeberg et al ). Johnson et al () and Audigane et al () used two‐dimensional (2D) multiprocess models (flow and geochemistry) to investigate solubility, convective mixing, and mineral trapping.…”

Geologic carbon sequestration (GCS) is being considered as a climate change mitigation option in many future energy scenarios. Mathematical modeling is routinely used to predict subsurface CO2 and resident brine migration for the design of injection operations, to demonstrate the permanence of CO2 storage, and to show that other subsurface resources will not be degraded. Many processes impact the migration of CO2 and brine, including multiphase flow dynamics, geochemistry, and geomechanics, along with the spatial distribution of parameters such as porosity and permeability. In this article, we review a set of multiphase modeling approaches with different levels of conceptual complexity that have been used to model GCS. Model complexity ranges from coupled multiprocess models to simplified vertical equilibrium (VE) models and macroscopic invasion percolation models. The goal of this article is to give a framework of conceptual model complexity, and to show the types of modeling approaches that have been used to address specific GCS questions. Application of the modeling approaches is shown using five ongoing or proposed CO2 injection sites. For the selected sites, the majority of GCS models follow a simplified multiphase approach, especially for questions related to injection and local-scale heterogeneity. Coupled multiprocess models are only applied in one case where geomechanics have a strong impact on the flow. Owing to their computational efficiency, VE models tend to be applied at large scales. A macroscopic invasion percolation approach was used to predict the CO2 migration at one site to examine details of CO2 migration under the caprock.

“…A pilot study in the San Juan basin is an example of CO 2 sequestration in a coalbed methane reservoir 4 and the Sleipner West field, offshore Norway, is an example where CO 2 has been injected into a saline aquifer 5 . There are fewer examples of CO 2 injection into coal seams and saline aquifers, but they do exist.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435.Abstract CO 2 Sequestration has been proposed as a possible means of achieving sustainable development objectives and calls upon petroleum industry technology and expertise. Commercial application of long-term CO 2 sequestration depends in large part on the ability to effectively model and verify the movement of injected gas. Software has been developed to both simulate CO 2 migration and to predict seismic responses as a function of time. The co-simulation of fluid flow and reservoir geophysical parameters during the life of the reservoir provides useful information about the feasibility and optimal timing of 3D time-lapse (4D) seismic surveys. When CO 2 sequestration is combined with EOR processes, the integrated flow model has the potential to help locate bypassed reserves, and to aid the reservoir characterization process by decreasing seismic processing time. The purpose of this paper is to demonstrate the applicability of the integrated flow model to CO 2 sequestration. An example using a dome-structured aquifer illustrates the technology.
