Petrel — Tutorial

For historical periods (History Matching), constrain your wells to follow actual reported fluid rates (e.g., Liquid Rate Control).

Open a or slice through the seismic volume along a specific inline or crossline. Fault Interpretation Navigate to the Seismic Interpretation ribbon. Select the Fault Interpretation tool.

Select the property (e.g., Porosity) and choose an averaging method. Use for porosity, and Harmonic or Geometric for vertical permeability. Facies Modeling (Discrete) Open Facies Modeling .

To start seismic interpretation:

Data import is foundational. Petrel handles a variety of formats, but the most common for beginners are and seismic data (SEGY) . You can import well headers, deviation surveys, logs, and formation tops using the Import function in the Input pane. A Petrel tutorial will almost always start by loading a well (LAS) and a seismic (SEGY) dataset. To keep your project clean and manageable, you should organize your loaded data into dedicated folders within the Input pane.

Convert your fault sticks into continuous (Linear, Listric, or Curved shapes).

: The step-by-step engine used to build the structural framework, populate properties, and initialize simulations. 2. Project Setup and Data Import petrel tutorial

Navigate to the , right-click, and select Import File . Follow these specific formats:

Now we bring well logs into the 3D grid.

Create a coarser 3D grid simulation model (e.g., combining four cells into one). Select the Fault Interpretation tool

Petrel is the industry-standard software platform developed by Schlumberger (SLB) for subsurface interpretation, seismic processing, and reservoir modeling. This tutorial provides a structured, step-by-step workflow designed to take you from raw data import to building a fully functional 3D geological model. 1. Introduction to the Petrel Interface and Project Setup

Have a specific Petrel question? Common issues include: "Why is my surface clipping above my faults?" or "How do I create a subset grid?" Drop a comment or consult the Ocean API documentation for advanced scripting.

If you work in oil and gas exploration, carbon capture and storage (CCS), or geothermal energy, you have heard the name . Developed by Schlumberger, Petrel is the leading platform for subsurface workflows, integrating seismic interpretation, geological modeling, petrophysics, and reservoir simulation into a single environment.

This tab contains variables, case outputs, and simulation vectors.

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
