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...

Ranking and categorizing large-scale saline aquifer formations based on optimized CO2 storage potentials and economic factors

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1483942

The process of selecting a CO2 storage site involves evaluating many potentially suitable sites in terms of their storage potentials as well as their associated technical and economic limitations. As such, it is useful to apply a ranking scheme that makes use of several different criteria and weight...

Fully implicit higher-order schemes applied to polymer flooding

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1483940

In water-based EOR methods, active chemical or biological substances are added to modify the physical properties of the fluids or/and the porous media at the interface between oil and water. The resulting displacement processes are governed by complex interplays between the transport of chemical sub...

Use of multiple multiscale operators to accelerate simulation of complex geomodels

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1483936

Multiscale methods have been developed as a robust alternative to upscaling and to accelerate reservoir simulation. In their basic setup, multiscale methods use a restriction operator to construct a reduced system of flow equations that can be solved on a coarser grid, and a prolongation operator to ...

Efficient flow diagnostics proxies for polymer flooding

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1481125

Flow diagnostics refers to a family of numerical methods that within a few seconds can compute visually intuitive quantities illuminating flow patterns and well connections for full 3D reservoir models. The starting point is a flow field, extracted from a previous multiphase simulation or computed b...
