The workflow begins with the Petrel Foundation module, which manages all data loading, well correlation, and basic mapping. From there, the Seismic Interpretation module allows geophysicists to interpret horizons and faults in 2D and 3D. Advanced variants like Seismic Attribute Analysis and Seismic Reservoir Characterization transform raw seismic volumes into quantitative rock property maps (e.g., acoustic impedance). Simultaneously, the Well Correlation module enables stratigraphers to build a high-resolution layer-cake model of the geology at the wellbore.
For more complex scenarios, specialized modules add detail. Fracture Modeling (often via the "Kinetix" or similar fracture module) explicitly models natural fractures as discrete features, which dominate flow in tight reservoirs like shales. The Geomechanics module calculates stress and strain, predicting risks like sand production or caprock integrity loss during injection. petrel modules
With the structural framework built, the 3D Gridding module constructs a corner-point grid—a mesh of millions of cells that fills the reservoir volume. Onto this grid, the Petrophysical Modeling module populates properties like porosity, permeability, and water saturation using geostatistical algorithms (e.g., sequential Gaussian simulation or indicator kriging). This turns a geometric shell into a physical representation of rock quality. The workflow begins with the Petrel Foundation module,
