Summary:
Three-component multiwave seismic technology in combination with the 2D survey allows supplementing seismic images with more detailed information about the reservoir properties and the type of its saturation. This technology includes the construction of layer-by-layer velocity ratio (Vp/Vs) maps demonstrating the Poisson coefficient distribution. Theoretically, the Poisson's ratio should decrease in zones with high hydrocarbon saturation. The results of field experiments confirm this regularity. In practice, this methodology highly increases the efficiency of geophysical exploration and realizes a great economic potential.
