Migri is Migration
Risk software from Migris AS.
The development of the
software was started 1 October 2005 in
The aim of the project has
been to create a next generation hydrocarbon migration simulator that can be
used interactively to describe geologic risks at seismic scales. The first Beta
version of Migri was released in February 2006. Migri 1.0.0 was released to our
sponsor in September 2009.
Check existing and planned
versions of Migri at:
www.migris.no/migri/versions.html
and the Migri Bulletin Boards
Project members can obtain
Migri from migridownloads. The
home of Migri is www.migris.no/migri
Examples of Migri plots

The
Figure above shows release candidate 0.9.2-80131 of the Migri GUI with a
6-layer basin model where one of the layers is faulted. One of 3 profiles in
the 3D view is shown in the Profile view. A vertical well has been created
through cell (98,97) and shown in the Explorer/well view to the right. A
non-vertical wellbore has been imported from a LAS file and plotted with
well-property colour-coded.

Figure
above shows a few selected flow-paths on top of a carrier in 3D view. (Figures
below show more details for these flowpaths)

Flow-rates
along carrier in previous figure (darker colours suggest higher flow-rates)

We
remove the top of the carrier and view each flow-path in detail: Depth
colour-coded here.

And
here we see the same flow-paths with Vsh (shale content) colour-coded.

And
finally - we can study the details of the flow-rates within the sub-layers of
each flow-path.

If
we zoom very close we can see that each flow-path consists of many mesh-nodes with
widths and heights. Only some of them are migration stringers in this case.
Flow-paths typically merge along e.g. ridges, as shown here. For more details,
please take a look at our AAPG 2008 poster contribution (Sylta & Tømmerås,
2008)

Figure
above shows entry pressures (Pa) in 4 sub-layers within each of the lowermost 2
layers used in simulations below.

Figure
above shows hydrocarbon flow within 3 carriers of the sub-layers of the
lowermost 2 layers and colour-coded depth of horizon above.

Figure
above shows modelled catchments areas of the lowermost 2 layers.
More
details of this new technology will be made available later.
