Modules: Petrel

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.

Once interpretations are complete, the Structural Modeling module constructs the 3D framework of the reservoir. This involves creating a network of fault surfaces and a series of horizons that define the reservoir’s layers. The Fault Analysis module goes further, allowing users to assess fault seal potential—critical for determining if a fault will trap hydrocarbons or allow them to leak away. 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. For more complex scenarios, specialized modules add detail
