The characterisation of candidate sites for geological
storage of CO_2 is most likely highly uncertain and
based on geostatistical methods. Therefor,
the assessment of storage potential needs to be done in a
statistical framework. This requires fast numer ical methods
to create multiple realizations for screening, e.g.,
streamline or semi-analytical methods. Typically fractures
and wells provide conduits for leakage and needs
to be modelled by the simulator tools.
In the proposed project, PhD student Håko n Hægland
will develop streamline methods to handle CO_2 transport through
fractured or faulted media. In particular he will develop
streamline methods for irregular and nonconforming grids
that are typically created by the modelling of fractured or
fault ed zones. The work will be done at Princeton University, USA,
in collaboration with Professor Michael A. Celia.
The work will be a part of Hægland's PhD project
entitled "Streamline Calculations for Multiphase Flow
on Irregular Grids" (see attachment), which is part of
the project "Reservoir Simulation on a Geological Scale" financed
by the Norwegian Research Council
(see http://www.sintef.no/static/AM/GeoScale/).
