These results make it easier to see how and where wells interact with the reservoir and each other.
It is possible to select exactly what wells to investigate, and even the possible *opposite flow* part of the well.

#### Method
The calculations are performed by a library called [opm-flowdiagnostics](https://github.com/OPM/opm-flowdiagnostics) developed by [SINTEF Digital](http://www.sintef.no/sintef-ikt/#/).
This method is based on the presence of a flux field, and will use the flux field written to the eclipse result data file (Cell Properties: FLRGAS, FLRWAT, FLROIL) if available. If these are not available, the flux field is estimated by algorithms in the opm-flowdiagnostics-applications library based on pressure differences, relative and absolute permeability and viscosity. Other effects are not included.

A more elaborate description of the technique and how it can be utilized, can be found at Sintef's [web site](http://www.sintef.no/projectweb/mrst/modules/diagnostics/). The MRST tool described is a Matlab predecessor of the flow diagnostics calculations developed for ResInsight.
