ARK CLS Seismic Spectral Blueing

Shapes spectra of seismic data to be consistent with the Earth's reflectivity

Overview

SSB sections are usually easier to interpret and reveal more information about the subsurface. Small scale faulting, not seen on the original section, is often observed. Such additional information can be useful during well planning. SSB is rapid, easy to use, inexpensive, robust and does not require expert users.

Features

SSB provides a set of customisable charts and a seismic view window. Both are updated in real time allowing you to quickly determine the parameters for generating an optimum blueing operator. Using seismic directly from the Petrel software the analysis can be performed rapidly. The saved SSB operator can be applied to the input seismic volume via the SSB process or the Workflow Manager.

Specifications

Provides a globally optimised spectral shaping of 2D and 3D seismic data to be consistent with observed Earth's reflectivity.

Integrates seamlessly with Petrel software allowing seismic to be accessed and the spectral blued operator saved as a wavelet.

SSB can assist in the interpretation of small scale faulting which may not be visible on the original seismic data.

Provides a true real time seismic view of spectral blued data.

With immediate feedback you will have the time to do many "what-ifs" allowing you to determine the optimum spectral blueing operator.

The SSB process is rapid, robust, and inexpensive which eliminates the need for expert users.

Seismic Spectral Blueing (SSB) process

The SSB process provides a facility to create an SSB operator and to apply the operator. Creating an SSB operator is achieved by clicking the [Create Operator ...] button to launch the Analysis tool. After an SSB operator has been derived and saved it can be applied here to generate an SSB cube. The saved operator can also be applied via the Workflow Manager.

Seismic Spectral Blueing Main Analysis Window

The SSB main analysis window displays various charts which will assist you in deriving an optimum spectral blueing operator that can be applied within the SSB process or used in your workflow. The analysis window along with the seismic view window gives you immediate real time feedback as you tweak the various SSB design operator parameters.

Seismic view window showing input seismic data

Here, the seismic view window displays the input seismic data you are using to derive the spectral blueing operator. This input seismic data is not affected by anything you do.

Seismic window showing real time spectral blued data

Seismic view window displays, in real time, the spectral blueing data of a selected in-line or cross-line. Using this window in conjunction with the analysis window will allow you to derive an optimum spectral blued operator. Toggling between the input seismic and output blued will give you immediate feedback showing the improvements obtained by applying the SSB operator.
