Chapter 1. Introduction

• Steering: attributes and filters are calculated along user-driven or data-driven directions.

• SSIS (Sequence Stratigraphy Interpretation System)

• PSDM-VMB: PSDM and VMB are new plugins. The VMB (by dGB) supports vertical update and horizontal based modules for velocity picking. The PSDM plug-ins are developed by Geokinetics, our partner in the PSDM-VMB project. It supports Tomography, Kirchhoff migration, and a processing job builder.

• CCB: Common Contour Binning is used to detect subtle hydrocarbon-related seismic anomalies and to pin-point gas-water, gas-oil, and oil-water contacts. CCB uses the power of stacking to enhance such anomalies. If we stack all traces along the same contour line, we can expect the hydrocarbon effect to stack up while stratigraphic variations and random noise will be canceled out.

• MPSI: This technology developed by Earthworks and Ark cls, is considered the fastest stochastic inversion scheme currently on the market. MPSI is implemented as a series of five attributes in OpendTect's attribute engine. The attributes include: Model builder, Error grid, Deterministic inversion, Stochastic inversion, and utilities

• Neural Network analysis: Both supervised and unsupervised neural networks allow generation of meta attribute volumes that highlight any object of interest (Chimney, Salt, Faults, etc.).
