Virtual element method for geomechanical simulations of reservoir models

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1509649

In this paper, we study the use of virtual element method (VEM) for geomechanics. Our emphasis is on applications to reservoir simulations. The physical processes behind the formation of the reservoirs, such as sedimentation, erosion, and faulting, lead to complex geometrical structures. A minimal r...

Vertical Equilibrium Flow Models with Fully Coupled Geomechanics for CO<sub>2</sub> Storage Modeling, Using Precomputed Mechanical Response Functions

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1498211

Vertical equilibrium (VE) models have proved to be attractive for simulation of \co storage scenarios. Their primary advantage is a substantial reduction in computational requirements compared to standard 3D simulation tools. In this work, we aim to include the effects of geomechanics on aquifer flo...

Modeling geomechanical impact of fluid storage in poroelastic media using precomputed response functions

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1495417

When injecting CO2 or other fluids into a geological formation, pressure plays an important role both as a driver of flow and as a risk factor for mechanical integrity. The full effect of geomechanics on aquifer flow can only be captured using a coupled flow-geomechanics model. In order to solve thi...

Using sensitivities and vertical-equilibrium models for parameter estimation of CO2 injection models with application to Sleipner data

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1487593

A key part of planning CO2 storage sites is to devise a monitoring strategy with proper modelling support. Herein, we show how a simulation framework that incorporates adjoint-based sensitivities can be combined with time-lapse seismics to update forecast models of the migrating plume, investigate t...

Categorization of Norwegian Continental Shelf formations in terms of geological CO2 storage potentials

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1483950

In the present study, we use data published alongside the Norwegian Petroleum Directorate (NPD) storage atlases to further investigate the storage capacity of 23 formations found in the Norwegian Continental Shelf. Our goal is to categorize the formations according to the main limiting factors for l...
