Abstract
Summary In this paper we present a case study from onshore in the north Western Siberia deepwater sediments, where quantitative interpretation of seismic inversion attributes was based on a rock physics and statistical framework. A lot of companies try to implement Poisson Impedance for encasing contrast between sandstone reservoir and shale for determining situation where difference is small. Poisson Impedance is a difference between the P-impedance and scaled S-impedance (PI=Ip-c*Is). Reservoir and tight sandstones in Achimov formation has approximately the same values of Poisson Impedance compared to the appropriate separation between shale and sandstone. Therefore, deterministic simultaneous inversion along with a Bayesian classification are followed in order to identify distribution of lithofacies using Poisson Impedance and P-impedance.
