Reservoir characterization proves to be very challenging with a limited dataset and/or when correlation between the data is poor. Full utilization of the available data to extract maximum information is the goal of every geoscientist. We have followed a procedure of geobody (distinct geological features) extraction based on the Previous HitfaciesNext Hit Previous HitanalysisNext Hit. This approach can be summarized in two steps:

1) Structural: Extracting the main reservoir body based on Previous HitseismicNext Hit envelope.
2) Reservoir Characterization based on log and Previous HitseismicNext Hit Previous HitfaciesNext Hit Previous HitanalysisNext Hit.

The Previous HitseismicNext Hit Previous HitfaciesNext Hit classification is based on principal component Previous HitanalysisNext Hit which is a Previous HitseismicNext Hit pattern recognition methodology. The well logs have high reliability in the sample point but are restricted laterally. Thus calibrating the Previous HitseismicNext Hit Previous HitfaciesNext Hit with the log Previous HitfaciesNext Hit provides a trend for the interpolation of these Previous HitfaciesNext Hit.
On the basis of Previous HitfaciesNext Hit classification the Previous HitseismicNext Hit amplitude features are clustered, thereby exposing geobodies. A connectivity Previous HitanalysisNext Hit is performed throughout and each geobody is given a unique ranking and volumetrics is calculated respectively. This approach is illustrated on a 3D Previous HitseismicTop data set of a channel deposit.
