Volatile markets and harsh locations and downhole conditions pose severe challenges for
ensuring safe and long-lasting intact well conditions. Well integrity is a crucial issue in the …

Reactive transport modeling is a process-based approach that accounts for advection,
diffusion, dispersion and a multitude of biogeochemical reactions. The occurrence of these …

This paper describes a fully coupled finite element/finite volume approach for simulating
field‐scale hydraulically driven fractures in three dimensions, using massively parallel …

Among the various risks associated with CO 2 storage in deep geologic formations, wells
are important potential pathways for fluid leaks and groundwater contamination. Injection of …

In this work, we present the application of a fully coupled hydro‐mechanical method to
investigate the effect of fracture heterogeneity on fluid flow through fractures at the laboratory …

This work comprehensively reviews the equations governing multicomponent flow and
reactive transport in porous media on the pore-scale, mesoscale and continuum scale. For …

Effective geologic sequestration of C02 requires long-term storage with very low leak rates.
Injection wells are an obvious leakage pathway for C02 because they perforate the …

Fractures are ubiquitous and important features in the Earth subsurface (Berkowitz 2002;
Pyrak-Nolte et al. 2015). They are created as a result of rock failure when the critical stress …

The purpose of this study is to examine previous works undertaken that characterise the
cement alteration due to its exposure to CO 2-bearing fluids attacking on the interfaces of …

Defining chemical and mechanical alteration of wellbore cement by CO2-rich brines is
important for predicting the long-term integrity of wellbores in geologic CO2 environments …
