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. Migri 1.0.0 was released to our sponsor in September 2009.
Examples of Migri plots
The Figure above shows 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.
