CO2 mobility reduction using foam stabilized by CO2- and water-soluble surfactants
(Peer reviewed; Journal article, 2020)Foam can reduce CO2 mobility to improve the sweep efficiency during injection into subsurface geological formations for CO2 storage and enhanced oil recovery. However, CO2 foams are thermodynamically unstable, so they must ... -
CO2 pipeline integrity: A coupled fluid-structure model using a reference equation of state for CO2
(Peer reviewed; Journal article, 2013)We present a coupled fluid-structure model to study crack propagation and crack arrest in pipelines. Numerical calculations of crack arrest, crack velocity and pressure profiles have been performed for steel pipes with an ... -
CO2 pipeline integrity: A new evaluation methodology
(Peer reviewed; Journal article, 2011)A coupled fluid-structure model for pipeline integrity simulations has been developed. The pipe material and fracture propagation have been modelled using the finite-element method with a local fracture criterion. The ... -
CO2 Pipeline Integrity: Comparison of a Coupled Fluid-structure Model and Uncoupled Two-curve Methods
(Peer reviewed; Journal article, 2014)One challenge in CCS is related to the prevention of running-ductile fracture in CO2-carrying pipelines. Commonly used tools for ensuring crack arrest in pipelines hinge mainly on semi-empirical models, which may not be ... -
