Petrel — Tutorial
Petrel is an industry-standard software suite developed by Schlumberger (SLB) used for geological modeling, geophysical interpretation, and reservoir engineering. It allows users to visualize subsurface data, build 3D static models, and prepare inputs for reservoir simulation. The software operates on a Windows environment and utilizes a project-based file system (.pet files).
The Petrel E&P software platform is a powerful tool for geological modeling, offering integrated workflows from seismic interpretation to reservoir simulation. Mastering it requires a structured approach, starting from project setup to complex property modeling. Project Setup and Data Import
Before any modeling begins, you must establish a solid project framework to ensure all subsequent data is geographically and physically accurate.
Initialize Project: Launch Petrel and navigate to File > New Project. Set Coordinate Reference System (CRS)
: Access Project Setup > Project Settings to define your CRS and units. It is recommended to use the metric system for static modeling. Import Well Data: Use the Petrel Basic Manual
as a guide for loading well headers first, followed by deviations and finally well logs (typically LAS files).
Seismic Data: Import seismic cubes in SEG-Y format to serve as the foundation for structural interpretation. Structural and Grid Modeling
Once your data is loaded, you can begin constructing the 3D framework of your reservoir.
Horizon Interpretation: Use manual or automated autotracking methods to identify reflection events and insert new horizons.
Fault Modeling: Define faults using "key pillars" to represent their dip, azimuth, and shape in 3D space. petrel tutorial
Make Simple Grid: Use the Make Simple Grid wizard to create a 3D grid based on skeletons or available surfaces. You can set specific X, Y, and Z limits to define the model's thickness and extent.
To get started with the basics of setting up your first project:
Petrel is a comprehensive software platform by Schlumberger used for collaborative workflows in the exploration and production sector of the petroleum industry . This guide provides a foundational workflow for starting a project and building a 3D geological model. 1. Project Setup and Data Import
The first step is establishing a workspace with the correct spatial parameters. Create Project: Go to File > New Project .
Set CRS: Select the Coordinate Reference System (CRS) appropriate for your project's geographical location via Project Settings .
Import Well Headers: Use Home > Import File and select Well heads .
Import Well Logs: Right-click on the "Wells" folder, select Import on Selection, and choose Well logs (ASCII) .
Import Seismic Data: Use Home > Import File and choose SEG-Y seismic data .

Petrel is a high-end software platform used in the oil and gas industry for everything from seismic interpretation to reservoir simulation
. Below is a high-level "story" or workflow for a typical project, ranging from initial setup to dynamic modeling. 1. Project Setup and Interface
The journey begins by establishing the "physical world" of your project. Create Project : Start by selecting New Project Set Coordinates (CRS) : You must define a Coordinate Reference System
(CRS) so your data sits correctly on the map. This is done via Project Setup > Project Settings Define Units
: Choose between Metric or Field units for measurements like depth, volume, and pressure. Navigating the UI : The interface is divided into the Explorer panes (data trees), the Window display area (where the tools live). 2. Data Import and Visualization Before building models, you need raw data. Import Wells & Logs
: Import well data like LAS files. You can display these in a Well Section Window to correlate different layers. Seismic Data
: Load seismic volumes to interpret faults and horizons, which form the "skeleton" of your reservoir. Quality Control (QC)
: Use 3D windows to visualize your wells and seismic data together, ensuring they align correctly in space. 3. Static (Geological) Modeling This stage builds the 3D structure of the reservoir.

Before importing data, you must define the environment where your model will live. Coordinate Reference System (CRS): Setting the correct Coordinate Reference System
and units (Metric vs. Simulation units like Eclipse) is the first critical step. The Ribbon Interface:
Similar to Microsoft Office, Petrel uses tabs (Home, Stratigraphy, Seismic Interpretation, etc.) that change based on your selected "perspective". 2. Data Ingestion
Petrel acts as a "digital geophysical workshop," integrating diverse datasets into one environment. Hands-On-Start to Petrel 01 Sep 8, 2560 BE —
Here’s a short, informative piece on Petrel Tutorial — written for a geoscientist or student new to the software.
Now we bring well logs into the 3D grid.
Faults break the continuity of rock layers.
Create Surface. This generates a planar fault surface.An empty grid is a geometric skeleton; property modeling adds the “flesh”—distributing rock and fluid properties. This is a geostatistical exercise. Common properties modeled in Petrel include:
In a tutorial setting, a simple Facies + Porosity workflow is ideal: first, upscale well logs to the grid (averaging curves within each cell), then perform SIS to propagate facies away from wells, and finally simulate porosity within each facies type. Petrel’s Geostatistical Modeling menu offers interactive variogram fitting; a common beginner mistake is ignoring variogram range and anisotropy, resulting in “nugget-effect” noise.
Certainly! However, since "Petrel Tutorial" could refer to various resources (e.g., a YouTube series, a PDF guide, a paid online course, or a university handout), I’ll provide a general review based on common features of introductory Petrel tutorials. If you have a specific tutorial in mind (e.g., from SLB, a specific instructor, or platform), please clarify for a more tailored review.
