AVO

• AVO and seismic inversion technologies have merged!
• Significant resolution improvement over sub-stack or post-stack based methods
• Testing has shown that coupled inversion yields a better reservoir prediction than independent inversion
• Robust in the presence of non-AVO friendly dipping and incoherent pre-stack noise
• Outputs well-calibrated volumes of P-wave, S-wave and Density!

 

 

 

 

SIP is developing a proprietary AVO software called AVOdb

AVOdb is a logical endpoint for regional Rock Physics studies. Its aim is to make the best prediction of AVO response at a prospect using the rock property trends. It is designed to be primarily an interpreter tool.

Data Summary

Location and selection information, table of offset well, DHI information for specific stratigraphic intervals.

AVO half-space response curves

AI:GI crossplots

• Displays AI:GI crossplot
  • Contributing wells
  • Weighted averages
  • Interactive Fluid & Lithology projection angles
• Will also display other AVO crossplots
  • Intercept vs Gradient
  • Far vs Near
  • Others?

Synthetics

Can build angle-stack synthetics for simple fluid contact reservoir models or wedges. Default mode uses predicted rock properties for the given depth and location.
