Your journey begins with the software's core interface. Before learning any single workflow, you must become comfortable navigating Petrel’s four main functional windows: (data source), Models (work achievements), Windows (interactive interface), and Processes (tool entry), as most basic operations are performed in the Input and Processes panes.
Use for permeability to ensure that the effective directional flow characteristics ( ) are mathematically preserved in the coarser model. 8. Dynamic Simulation Setup and History Matching
The final step involves quantifying the uncertainty in your models. The tool allows you to perform sensitivity analysis, uncertainty assessment, and optimization on your reservoir models.
Open a and select dynamic properties like Pressure or Water Saturation . Use the player animation buttons at the bottom of the screen to watch your fluid contacts change, sweep efficiency evolve, and pressure deplete over the lifetime of your production forecast. To help tailor future tutorials, let me know: petrel tutorial
Open to subdivide the space between major horizons into distinct geological formations based on your well tops. Open Layering to define the vertical resolution (
While seismic gives you the big picture, wells provide the "ground truth." This module integrates well data into your evolving 3D model.
Well correlation allows you to refine your structural understanding by tracking specific geological markers across the field. Your journey begins with the software's core interface
If you are working with deviated or horizontal wells, you must load a trajectory file.
A model is only as reliable as the data fed into it. Petrel supports a wide array of industry-standard file formats for seismic, well, and spatial data.
Divide the grid into vertical layers within horizons. Petrophysical Modeling: Open a and select dynamic properties like Pressure
If you get lost in a dialog box, look for the or the drop arrow . Petrel uses a "Blue Arrow" system to drop selected items from your Input pane directly into tool settings. It’s the fastest way to populate fields without manual typing. Ready to go deeper?
A tutorial like the "Petrel Geophysical Interpretation" course provides a detailed, hands-on learning experience for these fundamental geophysics workflows .
Click on a clear, distinct reflector to place a seed point. Open the 2D/3D Seeded Autotracker settings. Adjust the correlation threshold and amplitude constraints, then press Run to let Petrel automatically map the horizon across the entire volume.
Use an for porosity data and a Geometric or Harmonic Mean for permeability curves. Facies Modeling (Discrete Properties)
as a guide for loading well headers first, followed by deviations and finally well logs (typically LAS files).
