Reservoir Services - Petroelastic Services

Geotrace Reservoir Services applies petroelastic analysis to characterize the seismic responses and/or signatures of various rock and fluid properties in a field or basin.  Petroelastic studies are a practical yet powerful extension of petrophysical analysis and a gateway from geology and petrophysics into the geophysics and seismic expression for the asset team of oil and gas companies. It models the interaction between rock/fluid/pore size/pressures and other properties then translates them into a  seismic response, thus providing explorationist a better understanding of what their seismic section is telling them in terms of rock and fluid properties, particularly for targeted reservoir formations.

The petroelastic services offered are:

• Digital Log Database
• Well and digital log cataloging
• Log editing, conditioning and environmental corrections

• Petrophysical Analysis
• Petrophysical parameter calculation

• Petroelastic Analysis
• Fluid substitution for gas, oil and water using in situ rock and fluid properties
• 1D petroelastic modeling for the seismic signatures of rock and fluid properties
• Synthetic seismograms for well correlation
• Synthetic CMP gathers for AVO modeling
• Check shots and well calibration
• Resolution effect on synthetic seismograms and AVO responses
• Fluid effect on synthetic seismograms and AVO responses
• 2D petroelastic modeling
• Vertical incident ray for 2D stratigraphic model
• Synthetic 2D responses for zero offset response and stack of AVO model response
• Sensitivity modeling
  • 1D and 2D model responses of rock and fluid properties
  • Rock property effect on seismic responses: Vp, Vs, density, porosity, thickness, mineral contents, etc.
  • Fluid property effect on seismic responses: fluid type, GOR, saturation, etc.
  • The combination effect of rock and fluid properties on seismic responses
