Inversions

Inversion is a technique that combines surface-acquired seismic data and well log data to develop a model of subsurface layers and their thickness, density, and P- and S-wave velocities. Seismic inversion provides a means to estimate rock properties from seismic data.

ION offers a variety of different inversions including:

  • Acoustic impedance inversions
  • Shear impedance inversions
  • Elastic inversions
  • Simultaneous inversions
  • Joint inversions

Accurate Earth Reconstructions with New Seismic Inversion Approach

Regardless of subsurface geology, the need to leverage seismic and well information to build more accurate earth reconstructions is critical in today’s onshore and offshore provinces.  Our new PrecisION compressed seismic inversion approach is designed to meet these challenges by helping clearly identify layer boundaries required for prospect generation, well planning, and completions design activities while also providing quantifiable and risk assessments of rock properties.

Through the use of pre-stack simultaneous inversion and joint inversion techniques, we can calculate important attributes such as density, Vp Vs, lambda (λ), and mu (μ). These can then be used to calculate reservoir properties such as porosity, brittleness, or fluid-bearing characteristics of reservoirs.

The Reservoir Services Difference

A key factor in generating quality inversions is the expertise of the team doing the work. On average, our experts have 25+ years of experience providing seismic inversion project services. Experience and understanding of the reservoir is the biggest differentiator in any inversion project.
