Blueback Rocks Velocity

Efficient and versatile velocity modeling.

Blueback suite for velocity modeling

Transparent and easy velocity model building workflows for interpreters.

Faster and more accurate results

Time to depth conversion represents one of the most intimidating workflows in reservoir characterization. A major key aspect is the ability to analyze data reliably.

Blueback Rocks Velocity extracts velocity parameters and seismic out of both well and seismic data, which allows the interpreter to build high-quality velocity models.

Fully integrated, the suite of tools lets you visualize and understand velocity trends in a clear and transparent way while building an accurate velocity model for full confidence in the data used for domain conversion. The technology has been developed following specifications given by a major operator in the North Sea.

Calibrating seismic velocity

The Blueback Rocks Velocity tool allows interpreters to choose between several methods to calibrate seismic velocities against well velocities.

Reduced time spent on velocity modeling
No need to build a complex 3D grid model
Improved quality control

Velocity analysis

Transparent and interactive workflow to define the most appropriate velocity function for each layer, visualizing interval velocity maps as you change parameters.

Several velocity model functions available
Meaningful and consistent velocities
Reliable and accurate results

Detrending

Produce detrended and scaled interval velocity maps using seismic interval velocities as input. The results can be saved in the Petrel* E&P software platform tree as surface attributes.

Interactive workflow
Integrate detrended results in velocity model building
Alternative workflow for seismic velocities

Optimized residuals

The depth optimization step lets the user analyze depth residuals and define a strategy to adjust velocities to minimize residual values.

Map oriented, simple, or advanced methods
Closer residual values to reference markers
Crucial aspect of velocity modeling

Horizon consistent Dix

This tool features computing of horizon consistent interval velocities from root-mean-square velocities (Vrms). The results can be saved as surface attributes, point-sets or seismic volume and used as direct input.

Based on Dix approximation (1955)
Following the horizons above and below
Accurate and fast method

Depth conversion

The Blueback Rocks Velocity tool enhances the creation of velocity cubes to depth convert 3D seismic, interpretation faults, surfaces, points and polygons.

Generate outputs as required
Scalable with your hardware
Directly use results in Petrel processes

Petrel * is a mark of Schlumberger
