Extending HyVR

The HyVR package is a work in progress. It has been implemented in Python in order to make it accessible for researchers, easily customisable, and hopefully somewhat easy to extend to suit the needs of future research. In this section I have included some tips on ways to extend the HyVR source code.

Adding more geometries

HyVR has been set up in such a way to facilitate the implementation of additional hydrofacies assemblage geometries.

In order to generate new types of geometries a new architectural element class has to be added (probably in classes/ae_realizations.py) and a new geometry class has to be generated (similar to classes/trough.pyx).

Each geometry class needs a constructor that sets all the random values, e.g. dip, azimuth, facies etc. Additionally a assign-function is necessary that assigns facies, azimuth and dip to a grid cell with given coordinates.

When adding geometries, we suggest reviewing the code for the existing geometries to see how it is currently implemented. This should provide a reasonable idea of how to put a new geometry together.

The HyVR wish list

Any modelling project will have ‘areas for growth’ (as opposed to weaknesses). I have identified some things that I would like HyVR to have, but that are outside of the scope of my PhD research (and funds…). Perhaps you have the time and need to complete these yourself?

• Some level of conditioning, or improved interfacing with multiple-point geostatistical packages.

• Interaction of extruded parabolas, as well as more complex/realisitic configurations of channel deposits (e.g. point bars).

• Utilities for deriving HyVR simulation parameters from transitional probability geostatistics.

• Simulation of chemofacies.

• Better trough placement

• Horizontally rotated grid
