Petrel - Tutorial

Similar to Microsoft Office, Petrel uses tabs (Home, Stratigraphy, Seismic Interpretation, etc.) that change based on your selected "perspective". 2. Data Ingestion

Creating an accurate 3D grid is the foundation of reservoir characterization.

Use the "make horizons" function to quickly generate geological layers from imported surfaces.

Pillar gridding creates the foundational 3D framework mesh based on your fault geometry. Select from the process diagram. petrel tutorial

The well header file contains spatial information for each wellbore.

The Petrel tutorial journey—from blank project to a fully populated 3D model—mirrors the geoscientific method: integrate disparate data, interpret structure, populate properties, and quantify uncertainty. While mastering Petrel requires months of practice, the conceptual workflow remains constant. Import carefully, interpret structurally, grid sensibly, model geostatistically, and validate constantly. For the aspiring subsurface modeler, Petrel is more than software; it is a language for translating seismic echoes and well logs into actionable reservoir understanding. And like any language, fluency begins with the first tutorial step—importing that initial SEG-Y file, clicking OK , and watching the earth emerge from silence.

Use the Well Section Window to correlate log data and define geological markers. 3. Structural Modeling Workflow Similar to Microsoft Office, Petrel uses tabs (Home,

: Define faults using "key pillars" to represent their dip, azimuth, and shape in 3D space.

direction) of the model. Choose between proportional slicing, follow-top, or follow-base options. Set layer thicknesses (e.g., 1 meter layers) appropriate for captures of sand-shale variations. 6. Property Modeling (Facies and Petrophysics)

The central area where you display 2D maps, 3D canvases, intersection windows, and well section views. Coordinate Reference System (CRS) Selection Open Petrel and create a new project: File > New Project . Use the "make horizons" function to quickly generate

Located on the left, this contains the Input tab (raw data), Models tab (structural and property models), Results tab (outputs), and Templates tab (color bars and property definitions).

Preparing the model for dynamic analysis in ECLIPSE or INTERSECT. Input fluid properties (PVT) data.

Pillar Gridding defines the lateral boundaries and skeleton framework of the 3D grid.
