... porosity reservoir characterization seismic data geological modeling correlation coefficient Abstract Seismic impedances calculated from logs show very good correlation to log porosities in wells penetrating the chalk reservoir in the Dan Field, Danish North Sea. This is the basis for an attempt...

... data are used to define spatial trends in the proportion of cemented beds; sequence stratigraphy provides the vertical constraints, and seismic data provide lateral constraints. The modelling approach has been tested using data from the TOGI area of the Troll gas field in the Norwegian North Sea...

... Abstract Statistical recognition of seismic reflection patterns is a useful aid to seismic data interpretation. The seismic texture classification classifies and recognizes seismic data into a limited number of categories each characterized by a distinct style of reflectivity. The basis...

... and discussed. The approach is based on a two conditioning steps: in a first step the spatial distribution of rock types is conditioned to 3D seismic data RMS-Response Phase Map; in a final step the simulated maps are conditioned to "hard" well data. A case study was selected in order to test a new approach...

... Abstract Reservoir-scale 3-D models used for planning horizontal wells are usually unsuitable to provide quantitative support for drilling decisions that are required to optimize well placement. This is a consequence of the scales at which well and seismic data are collected and represented...

... Abstract 3D seismic data is inverted directly for porosity by implementing a non-linear, globally optimised seismic inversion scheme. The technique takes into account the lithology dependent relationship between porosity and acoustic impedance without requiring the user to make a detailed...
