Overview

Petrel™ domain conversion enables quick generation of velocity models based on different types of velocity data.

3D velocity modeling using seismic velocities calibrated with well velocities.

Accurate depth conversion incorporating any velocity data type.

Domain conversion using seismic velocities calibrated with well velocities.

Integrated seismic-to-well-tie studies for optimal time-to-depth calibration.

Build velocity models of any size and dimension, from regional to reservoir scale.

Applications

Multiple velocity models can be built to test different velocity parameter scenarios and obtain a better understanding of the structural uncertainty.

Velocity model building and analysis at true exploration scale.

Benefits

Users can thoroughly calibrate wells with seismic velocities obtained from processing to build more accurate velocity models and use 3D grid properties for depth conversion, which is useful for conversion of complex structures, such as reverse fault and salt environments.
Conversions within the same domain (time-to-time and depth-to-depth) can be used for flattening, AVO, and 4D seismic workflows, as well as workflows calibrating prestack depth migration data to well markers.

Features

The standard layer-cake approach is used for velocity model construction, providing users with the freedom and opportunity to select velocity variations for each layer—preserving the relationships between faults and horizons.
Velocity functions handled are linear functions such as V=Vo, V=Vo+kZ, V=Vo+k(Z-Zo), and V=Vo+kT and average and interval velocity cubes or average grid properties.
QC tools can be created from the velocity model: point sets, time and velocity logs, time-to-depth and velocity functions, velocity maps, residual attributes on well tops, and well reports.
Uncertainty analysis can be performed using different seed numbers and variogram parameters to gain a better understanding of the structural uncertainty.
Domain conversion can be performed backward and forward between time and depth for any object, including surfaces, horizons, faults and multi-Z interpretations, points, well data (logs and tops), 2D and 3D seismic data, and pillar and stair-stepped 3D grids.
