Abstract
P237 THE 4D SEISMICS DISCRIMINATION FOR NOT OVERCOMPACTED RESERVOIRS Abstract. 1 Today the 4D seismics becomes an effective tool of hydrocarbon deposits development control. 4D seismics makes it possible to find out not drained zones and areas of a reservoir to check the displacement front advance etc. However for a certain class of reservoirs sensitive to external loads and suffering plastic deformation even at relatively small fluctuations in pore pressure the changes of the seismic signal due to hydrocarbons displacement by water will be overlapped (masked distorted) by the its change because of the reservoir system impedance increase in the
