... Techniques for reservoir characterization include core analysis, wireline log analysis, 3D reflection seismic data, crosswell tomography, vertical seismic profiles (VSPs) , transient pressure analysis, tracers, 3D geological modeling, geostatistical modeling of reservoirs, production history matching, fracture analysis, and reservoir fluid analysis (PVT analyses)

From page 72...
... Conventional 3D seismic data can provide structural data for an entire reservoir, but conventional surface seismic data can only image bodies of rock approximately 100 by 100 by 100 feet. Seismic data cannot, therefore, directly provide data on many of the most important reservoir properties like porosity, permeability, and fluid saturations.
