Nasser Bani Hassan,Senior Geophysicist at ERCE, presented results of a seismic inversion generated using cutting-edge seismic technology at the London Petrophysical Society technical conference on 27th September 2018. His talk was entitled 'Incorporating FWI velocity in simulated annealing based acoustic impedance inversion - Jansz gas field case study'.
In this work, he introduced a high quality low frequency component from data driven Extended waveform inversion (XWI) velocities as an alternative to the conventional Low frequency component (LFC) models in absolute impedance solutions that highly correlates blind well data. The outcome of this study is the construction of seismic products that can accurately characterise petrophysical attributes of the rock layers away from well control. This study was conducted in collaboration with S-Cube, the company that constructed the FWI velocity model.
Having decades of experience in the quantitative interpretation, ERCE provides high-quality, world-class deterministic and statistical impedance inversion services in many petroleum basins across the world.
