Ji-Fi® (Joint Impedance and Facies Inversion)

With the Ikon Science alliance, FairfieldNodal now provides its clients with JiFi, an award-winning Bayesian pre-stack inversion with four unique benefits.

• Estimation of facies and impedance properties in a single step
• No conventional low-frequency model required
• Greater use of rock physics information from well logs
• An apparent increase in the resolution

Other seismic inversion approaches require a low-frequency model to fill in the information missing from the seismic bandwidth. Constructing these models is time-consuming and vulnerable to bias in the final inversion results. Ji-Fi avoids these issues by calculating the low-frequency model from a set of rock-physics trends that describe the elastic properties of individual facies.
