TL;DR: This paper summarises the results of a benchmark study that compares a number of mathematical and numerical models applied to specific problems in the context of carbon dioxide (CO2) storage in geologic formations.
Journal ArticleDOI
Numerical simulation of non-isothermal multiphase multicomponent processes in porous media.: 1. An efficient solution technique
TL;DR: In this paper, the authors developed a multidimensional numerical simulator to model non-isothermal multiphase multicomponent flow and transport processes in the subsurface, where they considered the transfer of mass and energy between the phases in addition to the flow processes such as advection and diffusion.
Journal ArticleDOI
Porosity–Permeability Relations for Evolving Pore Space: A Review with a Focus on (Bio-)geochemically Altered Porous Media
TL;DR: In this article, a review of porosity-permeability relations in simulation models on the REV scale is presented, with a focus on the porosity at which the porous medium becomes impermeable.
Journal ArticleDOI
Investigations on CO2 storage capacity in saline aquifers: Part 1. Dimensional analysis of flow processes and reservoir characteristics
TL;DR: In this article, a comprehensive reservoir parameter database with more than 1200 reservoirs is analyzed and statistical characteristics of reservoir parameters like depth, temperature, absolute and relative permeability, as well as capillary pressure are investigated.
Journal ArticleDOI
Darcy-scale modeling of microbially induced carbonate mineral precipitation in sand columns
Anozie Ebigbo,Adrienne J. Phillips,Robin Gerlach,Rainer Helmig,Alfred B. Cunningham,Holger Class,Lee H. Spangler +6 more
TL;DR: In this article, a numerical model is developed, capable of accounting for carbonate precipitation due to ureolytic bacterial activity as well as the flow of two fluid phases in the subsurface.
