Fugro-Jason releases new Jason Geoscience Workbench version
Software, Aug  25  2009 (Digital Energy Journal)

- Fugro-Jason has released JGW 8.1, the latest version of its Jason Geoscience Workbench.

The new version includes new AVO Attribute/Analysis and Full Waveform Synthetics applications, and a series of enhancements to existing products. JGW integrates geological, geophysical, petrophysical and rock physics information into a single consistent model of the earth.

The new AVO Attribute/Analysis module will allow extraction of seismic AVA or AVO attributes from pre- or partial stack seismic data. The options include:

Shuey 2-term (intercept and gradient);

Shuey 3-term (intercept, gradient and far-offset);

Smith and Gidlow (Vp and Vs contrasts);

Fatti et al. (Zp and Zs contrasts);

Gray et al. (λ, μ and ρ contrasts)

A Full Waveform Synthetics add-on application to the Well Log Editor allows full waveform Pre- and post-stack NMO synthetics with and without multiples to be calculated. Using well control, this module allows analysis of which seismic events are primaries and which ones are not.

Further enhancements to existing applications include a new Spectral Decomposition module, improvements to the deterministic inversion and wavelet estimation algorithms, and other usability enhancements.
