Petrel Domain Conversion

Geophysicists typically work in the time domain while geologists work with depth data. Petrel Domain Conversion reconciles these differences by helping you make depth data the rule rather than the exception.

Petrel allows you to quickly perform domain conversion backwards and forwards between time and depth. All the necessary steps are performed directly in your project, so there is no need to ever leave the friendly Petrel interface.

Petrel Domain Conversion involves two simple steps. First you create a velocity model and calibrate it to the available well markers. Next select the data you wish to domain convert, whether it is surfaces, horizon and fault interpretations, points, well data, 2D and 3D seismic, or 3D grids.

Benefits

• Domain conversion runs directly in Petrel, saving you time by avoiding unnecessary input and output of information.
• Perform domain conversion at any stage in your workflow. Build 3D models in either time or depth, and convert when it is convenient for you.
• Build multiple velocity models to test different velocity parameter scenarios and obtain a better understanding of structural uncertainty.
• Use a 3D grid property for depth conversion, useful for conversion of complex structures such as reversely faulted environments

Features

• Domain conversion of 2D and 3D seismic, surfaces, horizon and fault interpretations, points, wells and logs, well tops, and 3D grids.
• Uses a standard layer cake approach for domain conversion, giving you the freedom to select velocity variations for each layer, while preserving the relationships between faults and horizons.
• Velocity modeling and depth conversion can be run in the Petrel Process Manager, allowing you to generate a single workflow that spans both time and depth domains.
• Supported velocity methods include linear functions V=Vo, V=Vo+kZ, V=Vo+k(Z-Zo). Constants or surfaces can be used as variables.
• Can utilize externally generated velocity cubes to create velocity models.
• Supports conversion within the same domain (Time to Time and Depth to Depth), enabling AVO and 4D seismic workflows and the calibration of PreStack Depth Migration to well markers.
