The influence of depositional architecture of clastic sedimentary environments on
reservoir properties is well known. 3D-seismic attribute analysis is an established
technique for mapping this distribution of facies bodies in hydrocarbon exploration.
One aim of this talk is to compare results and quality of 3D and reprocessed
2D-seismic data and the implementation of sedimentary datasets in reservoir models.
One of the most common problems in reservoir characterisation is the scaling of rock
properties from seismic imaging down to the grain scale. Reservoir properties are
extremely influenced by horizontal and vertical permeability distributions within the
reservoir rocks. The lithologic control on petrophysical property variability has to
be known for an accurate prediction of productivity and as input parameter for
thermal-hydraulic modelling of the pay zones. The irreducible water content of
reservoir sandstones as an often undervalued factor in geothermal reservoir
characterisation will also be discussed.
