Interpretation/Reservoir
Better interpretation of reservoir propertiesThe additional information recorded by multicomponent surveys allow for better interpretation of reservoir properties:
  • Lithology discrimination
  • Fracture and stress identification and characterization
  • Fluid identification
PP-PS Interpretative Processing

By its nature, joint processing of PP and PS data has an interpretative element. It requires specialist applications to enable the data to be interpreted.

Due to the basic reflectivity differences between PP and PS data, as well as variations in PS arrival times, the final processed PS data can be difficult to work with independently. Therefore, it is necessary to register the PP and PS data with their respective synthetic seismograms, and convert the PS data into PP time. Alternatively both the PP and PS data can be converted to depth, which requires dipole sonic logs or multicomponent VSP data.

PP-PS Joint Inversion

PP- and PS-AVO and joint PP- and PS-inversion offer tremendous capacity for reducing drilling risk. The inversion process allows rock property information to be extrapolated from known well locations to yet-to-be drilled prospects. Having both PP and PS inversions available allows for non-boundary-driven Vp/Vs ratio computation.

PROMC

PROMC is the Hampson-Russell application designed to make multicomponent interpretation and modelling highly accessible:
  • Range of tools to help correlate events between datasets.
  • Joint inversion process that integrates all the available information into a detailed, optimized model of P and S impedance together with Vp/Vs ratio information.
  • Can convert PS- and S-wave seismic data to P-wave time to greatly simplify the interpretation process.
VectorVista
VectorVista
VectorVista is a dedicated workstation designed specifically to process and QC multicomponent data, proprietary to CGGVeritas. Key features include:
  • Receiver re-orientation
  • Shear statics derivation
  • Azimuthal anisotropy analysis
  • Hodogram displays
VectorVista includes a unique dual AVO (PP and PS) stratigraphic inversion. This uses a global optimization process which ties Vp/Vs from travel times with Vp/Vs from AVO attributes.
