Convert surface interpreted into structural framework surfaces (Top, Base). 5. Property Modeling and Upscaling Populating the 3D grid with geological properties. Make Geometrical Grid: Generate the 3D cell-based grid.

Divide zones into vertical micro-layers (e.g., proportional, parallel to top, or parallel to base) to match the vertical resolution of your reservoir well logs. 6. Property Modeling (Facies and Petrophysics) petrel tutorial

Divide the main structural zones into finer, vertically stacked layers (e.g., Make Geometrical Grid: Generate the 3D cell-based grid

Shift and stretch the synthetic trace to align perfectly with the actual seismic traces adjacent to the wellbore. Fault Interpretation Open a or standard 3D View . Property Modeling (Facies and Petrophysics) Divide the main

The Petrel tutorial journey—from blank project to a fully populated 3D model—mirrors the geoscientific method: integrate disparate data, interpret structure, populate properties, and quantify uncertainty. While mastering Petrel requires months of practice, the conceptual workflow remains constant. Import carefully, interpret structurally, grid sensibly, model geostatistically, and validate constantly. For the aspiring subsurface modeler, Petrel is more than software; it is a language for translating seismic echoes and well logs into actionable reservoir understanding. And like any language, fluency begins with the first tutorial step—importing that initial SEG-Y file, clicking OK , and watching the earth emerge from silence.
