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 …

This paper provides a review of the geomechanics and modeling of geomechanics
associated with geologic carbon storage (GCS), focusing on storage in deep sedimentary …

The presence of delaminations, apertures, fractures, voids and other unrestricted flow
channels in the wellbore environment substantially reduces wellbore integrity …

Fractures in geological formations may enable migration of environmentally relevant fluids,
as in leakage of CO2 through caprocks in geologic carbon sequestration. We investigated …

We present a set of reactive transport experiments in cement fractures. The experiments
simulate coupling between flow and reaction when acidic, CO2-rich fluids flow along a leaky …

Global warming is a pressing issue caused by the increase in greenhouse gas emissions,
with CO 2 contributing to 64% of total emissions. To reduce anthropogenic CO 2 emissions …

Wellbore leakage is complicated to understand due to the range of potential leakage
pathways and uncertainties regarding their capacities. In this study we present a novel …

The loss of well integrity in oil and gas and CO 2 injection wells provokes leaks that
potentially pollute underground water reservoirs and the surrounding environment. The …

Understanding CO 2-induced micro-structural changes at the imperfections in wellbore
cement is vital for assessing the risk of CO 2 leakage through wellbore cement under …

Wellbores are comprised by a steel casing surrounded by a cement sheath. The
microannulus is the typically very small annular or degraded space that may develop …
