Characterization of deeply buried heterolithic tidal reservoirs in the Smorbukk Field using inverted post-stack seismic acoustic impedance

摘要

Deeply buried reservoirs in Smørbukk Field play an important role in oil production from the Halten Terrace hydrocarbon province (Mid-Norwegian shelf). These heterolithic reservoir sandstones are sedimentary systems for which estimation of reservoir properties is challenging. The main problem is to derive realistic models of the lateral changes of porosities and permeabilities in the inter-well space. There is a very significant upside potential in producible reserves if infill production wells can be placed and completed in an optimal position with respect to reservoir quality.
