Tutorial: Petrel

Petrel is a popular workflow platform for geoscience and reservoir modelling. This tutorial gives you a concise, hands-on guide to go from data import to a simple static model and basic visualization. Follow each step in order; default settings are used where choices aren’t specified.

, connecting seismic interpretation, geological modeling, and reservoir simulation in a single environment. 1. Project Initialization & Setup

Well logs have a vertical resolution of inches, whereas grid cells are meters thick. You must average the log data into the grid cells that the wellbore intersects. Open . petrel tutorial

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.

Add horizons between faults. While default algorithm settings are often sufficient for a first pass, you can adjust the "blanking distance" around faults for better resolution. 3. Property Modeling Petrel is a popular workflow platform for geoscience

Model permeability next, using a cloud-transform or property-correlation function linked directly to your modeled porosity grid. 6. Volumetric Calculation

Define by specifying where the production casing is perforated within your 3D grid layers. You must average the log data into the

cells) for engineering simulators to process efficiently. Upscaling condenses grid layouts into larger, coarser cells while retaining regional flow dynamics. Create a coarser grid via the process.

Next, the tutorial teaches you how to construct the skeleton of your model: the . You’ll:

Use the to trace fault segments across consecutive inline and crossline profiles.
