ARK CLS Seismic Toolbox

A package of powerful software tools to enhance data

Overview

ARK CLS Seismic Toolbox includes the following powerful software Seismic Spectral Blueing, Seismic Colored Inversion, Seismic Net Pay and Seismic Feature Enhancement. These have evolved over may years into robust and effective solutions which have a proven track record and have helped geoscientist to maximise the information obtained from their sub-surface data.

Features

Based on research and techniques originally developed by Lancaster S, 2000, "Fast-track 'coloured' inversion" and Connolly PA, 2005, "Net pay estimation from seismic attributes", this software provides the interpretation geoscientist with easy to use tools to enhance and extract more information from seismic data. These tools have consistently delivered high quality results quickly.

Specifications

This plugin provides a globally optimised spectral shaping of 2D and 3D seismic data to be consistent with observed Earth reflectivity

SSB can assist in the interpretation of small scale faulting which may not be visible on the original seismic 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 Colored Inversion enables the rapid inversion of 2D and 3D seismic data

SCI provides a globally optimised inversion consistent with the observed behaviour from well logs

Includes the original SSB, SCI, SNP and SFE

Seismic Spectral Blueing can be used to increase seismic resolution. Seismic Colored Inversion of the blued volume provides better correlation of the sand units at the wells when compared to using colored inversion on original seismic. Seismic Net Pay is performed on surface attributes derived from the colored inversion volume. Seismic Feature Enhancement boosts flat-spots from your seismic data.

Seismic Spectral Blueing seismic viewer

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. The original and blued (RH panel) seismic can be viewed either side-by-side or in overlay mode.

Seismic Colored Inversion main analysis window

The SCI main analysis window displays various charts which will assist you in deriving an optimum colored inversion operator that can be applied in the SCI process or via the Workflow Manager. The analysis window along with the seismic view window gives you immediate real time feedback as you tweak the various SCI design operator parameters.

SNP generated attributes fully integrated into Petrel

NP provides a pre-analysis seismic attribute data preparation facility. This allows average band-limited impedance to be extracted from zero-crossing picks obtained from colored inversion data. The flexible and sophisticated Seismic Net Pay analysis module can be entered following seismic attribute data preparation to allow you to estimate net pay together with other surface attributes.

SFE

SFE provides a powerful technique for flatspot detection during early stages of your interpretation workflow. The input for SFE are Seismic data and a Polygon defining the seismic section to investigate the anomaly.
