Reservoir Characterization

Traditionally seismic data is used to develop geological models of structure and stratigraphy. However, the main goal in seismic surveying for petroleum is to find the lithology type and the presence of fluids. Therefore seismic amplitude information is used to infer rock and fluid properties. Well data has to be carefully and closely integrated with the seismic to calibrate the results. Additionally structural interpretation results and common geological knowledge are essential. Thus the success of reservoir characterization depends on the elaborate integration of various disciplines.

A successful seismic based reservoir property evaluation includes usually three steps: derivation of relevant rock properties from the seismic (for example through seismic inversion), rock physics transformation to relate the seismic derived parameters to reservoir parameters, and mapping of these parameters in 3D.
Eventually the results of a reservoir characterization study are usually used directly to build/update the static model for reservoir simulation.
