Petrel is grid-centric. A tutorial walks you through creating a that honors faults and horizons. Then comes upscaling well logs—averaging high-resolution log data into each grid cell. This is often the first “aha!” moment: watching your discrete well data populate the entire 3D volume.
The first step in any Petrel project is defining the framework to ensure data from different sources (seismic, wells, maps) aligns correctly. Coordinate Reference System (CRS): Found under File > Project Setup > Project Settings > Coordinates . You must define the projection and datum. Units System: Select between petrel tutorial
