Seismic driven inversion (no well information)
Recently reprocessed broadband GeoStreamer data contains both high and low frequencies to resolve thin sand bodies (injectites), reduce sidelobe artifacts, and allow accurate reflector picking. A regional rock physics approach using well data from fields and discoveries provides information on the elastic properties of reservoir lithology and fluid content. The prestack GeoStreamer data shows good correlation with the rock physics analysis and provides reliable estimations of rock and fluid properties away from the wells. Proving therefore that GeoStreamer data help derisk the interpretation and evaluation of these sand bodies.

Excellent Well-To-Seismic Tie
Right side: relative acoustic impedance results indicate what kind of fluid might be present. In zones with low Vp/Vs low acoustic impedance (blue) shows hydrocarbon potential. At the well location, the impedance log is displayed in the seismic frequency bandwidth.
