Mastering Petrel: A Comprehensive Tutorial for Subsurface Modeling
Petrel is a Windows-based software suite that integrates 3D visualization, seismic interpretation, geological modeling, well correlation, and reservoir simulation into a single, collaborative environment . It allows geoscientists and engineers to go from raw data to a fully-realized 3D static earth model, enabling confident decision-making in oil and gas exploration, field development planning, and production optimization.
If you have access to a recent version of Petrel, the most powerful integrated learning tool is . This module is embedded directly within the Petrel interface. It provides over 1,300 pages of content , more than 550 video guides , and over 150 pre-made guided workflows . Guru offers contextual help, meaning it shows you tips, workflows, and QC checklists relevant to the specific tool or process you are currently using in the software. It is an invaluable resource for both learning and daily productivity .
Use the "make horizons" function to quickly generate geological layers from imported surfaces. petrel tutorial
But let’s be honest: the interface can be intimidating. This tutorial will help you break through the "analysis paralysis" and get started with your first project. 1. Before You Begin: System Check
Set your project units (metrics or field units) immediately, as changing them later causes data corruption. Importing Data Types
This stage links the geological information from wells with seismic reflectors. This module is embedded directly within the Petrel interface
This phase transforms your interpreted horizons and faults into a sealed 3D cellular framework. Fault Modeling
Define your desired grid cell size (e.g., 50m x 50m) based on your computational limitations and geological complexity.
Similar to Microsoft Office, Petrel uses tabs (Home, Stratigraphy, Seismic Interpretation, etc.) that change based on your selected "perspective". 2. Data Ingestion It is an invaluable resource for both learning
Contains the structural grids, property models, and upscaled logs.
Now we bring well logs into the 3D grid.
Define major stratigraphic subdivisions between horizons.
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.
