f Subtle reservoir description from seismic, geologic and log data

Reservoir description can be greatly enhanced by integrating seismic, geologic and log data to create a detailed spatial lithologic and porosity model. A special pseudolithological log (PLL) technique has been introduced for this purpose. The PLL procedure has four major steps : well-log analysis (WLA), sedimentational analysis (SA), seismic broadband inversion (SBI) and lithologic inversion (LI).
