For the development of Joint Impedance and Facies Inversion (Ji-Fi) – a tool that accurately describes petroleum reservoirs and enables more efficient extraction.

3D seismic surveys revolutionised oil and gas exploration and production from the late 1970s, and gave geoscientists the vision of creating – from 3D seismic and well control – detailed 3D subsurface reservoir models to identify economic reservoir units.

New seismic inversion technologies evolved rapidly with the availability of increasing computer power and advances in related inversion theory. But results were inconclusive, requiring specialist interpretation, and were only partly useful in generating reliable reservoir models. Ikon Science’s Ji-Fi technology delivered a step change to fully use 3D seismic data, and all available well and geological constraints.

Using more than 2,000 person-years of analysis and algorithmic development on applied rock physics, seismic forward modelling and science-rich prediction tools, Ikon took a fresh look at the seismic inverse problem. Ikon’s scientists realised that rock-physics relationships, typically different for the various rock types or facies encountered, were not used effectively – or at all. By combining a more rock-physics and geological approach with new mathematical algorithms, Ikon enables usage of integrated prior regional and local geological models and analogues in the inversion of pre-stack seismic data, and is able to deliver a truly quantitative prediction of rock/fluid type and properties, and in the process deliver a step change in value.
