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.

The GXT Reservoir Solutions team offers a variety of different inversions including:

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

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 Solutions Difference

A key factor in generating quality inversions is the expertise of the team doing the work. On average, most of our Reservoir Solutions 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.
