Reservoir Appraisal - Solutions
Challenge

The role of seismic in field appraisal, field development and EOR is growing. Whether it is for well placement, infill drilling, or EOR feasibility, a comprehensive and high resolution static model for the reservoir is needed in order to obtain a quantitative estimate of the reservoir properties. However, re-development studies need to have a fast turnover despite containing significant amounts of well, seismic and production data. Other challenges for appraisal projects are to:

  • Model and interpret the seismic response to fluid injections (water, Miscible Gas, Chemicals).
  • Increase the resolution of the reservoir heterogeneities maps for infill drilling.
  • Assess the uncertainties of the heterogeneities maps and the associated impact on the production plan.

RSI Solutions
  • Post-stack seismic workflow which includes:
    • Developing rock physics models to calibrate rock properties at well control data points (iMOSS)
    • Data conditioning (AVATAR)
    • Attribute Extraction & Calibration at well control (iMOSS)
    • Seismic Facies Analysis (ATTRIB3D)
    • Kohonen self-organizing neural network facies classifications (LITHANN)
    • Automatic Fault Extraction (AFE)
    • Inelastic Seismic attributes (Q factor)
  • Pre-stack workflow including in addition to the above:
  • WISE:  Workflows for the integration of seismic and well log information with CSEM data to constrain reservoir content and extent
  • Multi-attribute geological and seismic stratigraphic interpretation of reservoir heterogeneities and rock properties.
