Petrel SeisKit plug-in

Spectral analysis, filtering, bandwidth extension, and amplitude gain for faster QC and image enhancement in the Petrel platform

Overview

The Petrel™ SeisKit plug-in is used for QC and image enhancement of stacked seismic data. It provides geoscientists with a way to efficiently validate the integrity of the seismic spectrum and bandwidth and perform scenario testing of bandwidth and amplitude compensation enhancements in the Petrel E&P software platform.

Volume selection capabilities (pictured) in the Petrel SeisKit plug-in enable you to create both 2D areas and 3D volumes of interest for customized seismic amplitude spectrum analysis.

The Petrel SeisKit plug-in calculates and applies scalars for residual amplitude analysis and compensation.

The Petrel Seiskit plug-in calculates and applies operators designed to flatten the average seismic spectrum in a time-variant manner, extending the bandwidth of your data. The spectral analysis tool in the plug-in then enables you to visualize and compare the results without leaving the Petrel platform.

The Petrel SeisKit plug-in compensates for seismic absorption in your data, enabling you to perform spectral analysis and visualize and compare the results.

Applications

Benefits

The plug-in brings previously unavailable functions to the Petrel platform, including bandwidth extension and Q-compensation, and enables analyzing an entire seismic volume at once or defining smaller 2D or 3D sections for analysis. The result? Faster QC and preconditioning of stacked seismic data for further processing and interpretation workflows.
