In Equinor, the Fast Model Update (FMU) approach is fundamental in reservoir modelling to chain different tools (both internal and vendor-based) to make automated workflow all the way from geological modelling to reservoir history matching and forecasting. XTGeo is an open-source Python library that can work with many different data formats and data types (e.g. 3D grids and maps) and do several operations that either vendor software cannot do or is hard to do in an automatic manner.
Hence it serves as a “glue” or “lubricator” in the FMU workflow. Some examples: (1) read a surface (map) and a seismic cube and automatically make several seismic attribute maps quite quickly. (2) read a reservoir simulation grid and a polygon, and inactivate cells within the polygon. (3) Read a well with logs and create a fence intersection with surfaces, cubes or 3D grids. (4) Read a flow simulation grid and make part of horizontal (see attached picture).
In the rendezvous, several demonstrations on usage will be given (both in notebooks, in web apps (Webviz) and inside the vendor tool RMS).
