... are produced using a gaussian collocated cosimulation algorithm, where well log porosities constitute the hard data input and seismic impedances are the soft data input. The simulated volume measures 1400-1525 102 m and is oriented parallel to lines and crosslines in the seismic data set. Simulated blocks...

... 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...

... Nord field in 1986 and processed during the following year. An interpretation made of the conventionally processed seismic data provided structural delineation of the Upper Jurassic. It was possible to interpret the top of the interval, corresponding to the Base Cretaceous Unconformity (base of Mime...

... Abstract A major challenge in well planning and in 3D reservoir modelling is to incorporate seismic information. In a North Sea setting, the wells constitute only a few pinpricks in the reservoir, while the seismic data are acquired in 3D over the whole field. Thus seismic data constitutes...

... 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...

...Implementation To implement the seismic inversion scheme the following tasks are performed: Correlation study between acoustic impedance and porosity from well logs. Log to seismic data calibration. Wavelet estimation. Seismic inversion for acoustic impedance and porosity...
