Advances in broadband quantitative interpretation

For almost 10 years now marine broadband seismic has provided the industry access to seismic data with a significant increase of seismic frequency bandwidth on both the low side of the frequency spectra and also on the high side. Seismic analysis and case studies in recent years using broadband seismic have revealed several benefits of broader seismic bandwidth for reservoir geoscientists - both for structural-stratigraphic interpretation and for quantitative seismic reservoir characterization and properties estimation. Pre-stack seismic inversion has been an excellent means to derive the full benefits and the value of acquired broadband pre-stack seismic for seismic reservoir characterisation and reservoir imaging. This paper presents case studies of recent analysis at various stages of the exploration-production asset life as well as some potential pitfalls to be aware of when using pre-stack broadband seismic data for improved target delineation, estimation of reservoir properties and ultimately de-risking of a prospect or well positioning. A case study for a shallow reservoir in a frontier exploration setting will also demonstrate some recent developments in the integration of Full Waveform Inversion and imaging using multiples for an improved low frequency model and more reliable pre-stack seismic inversion.
