Petrel | Tutorial

For forecasting prediction periods, switch well constraints to bottom-hole pressure (BHP) or economic limit constraints. Exporting and Running the Simulation (Eclipse/INTERSECT)

: Launch Petrel and navigate to File > New Project . Set Coordinate Reference System (CRS)

Manages color scales, lithology templates, and color tables.

The process in the Processes Pane allows you to view well logs side-by-side in a Well Section Window . This is your primary workspace for correlating rock layers from well to well. Key logs you'll encounter include:

Open a or 3D Window and check the box next to your imported seismic volume to display it. petrel tutorial

Right-click on a specific well or the Wells folder and select . Choose Well path/deviation (ASCII) ( . ) .

Create the skeleton of the grid between horizons.

Use the process to set well constraints.

Define your units (Metric vs. Imperial) immediately. Changing these mid-project is a recipe for disaster. 3. Data Import Basics The process in the Processes Pane allows you

This tutorial roadmap equips you with the theoretical foundation and practical knowledge to navigate Petrel's core workflows. While this guide provides an essential framework, hands-on experience is invaluable. Remember, this is just the beginning. Stay curious, practice with real-world data, and continue to explore the advanced capabilities of this powerful software as you refine your modeling skills.

Define your fluid zones by entering the or Gas-Oil Contact (GOC) depths.

In a Fundamentals course, you will learn:

Define PVT properties (Pressure-Volume-Temperature) using the tool to characterize oil, gas, and water behavior. Right-click on a specific well or the Wells

Upscale well logs (porosity, water saturation) to the grid cell resolution.

Open a new and select the wells along a specific cross-section trajectory.

To get started with the basics of setting up your first project:

Finally, the model is ready for . Once the cells are populated, Petrel can instantly calculate the total volume of oil or gas in place by summing the values of the cells. This is often the primary deliverable for management and investment decisions. If the model is destined for reservoir simulation (dynamic modeling), it often must be "upscaled." A geological model might contain 50 million cells, which is too many for a fluid flow simulator to handle efficiently. Upscaling coarsens the model, reducing it to perhaps 100,000 cells while attempting to preserve the critical reservoir properties.

Right-click on the Wells folder and select . Select your LAS (*.las) or LIS files.

This is the most critical step. Ensure your CRS (Coordinate Reference System) matches your data source (e.g., WGS84). Mixing these up early on will lead to wells being drilled in the wrong country!
