System and method for reservoir facies classification that segments both petrophysical and geophysical properties

A system for identifying reservoir facies in a subsurface region, the system comprising:

• a canonical analysis logical circuit;
• a user interface;
• and
• a data store;
• wherein the canonical analysis logical circuit comprises a processor and a non-transitory medium with computer executable instructions embedded thereon, the computer executable instructions to cause the processor to:
• obtain a set of seismic data points relating to the subsurface region, the set of seismic data points comprising petrophysical data points and geophysical data points, the petrophysical data points related to petrophysical characteristics of pore interconnection in the subsurface region, the geophysical data points related to geophysical characteristics of the subsurface region that are directly detectable via seismic signal analysis;
• generate one or more two-dimensional correlated petrophysical clusters of the seismic data points by clustering the petrophysical data points;
• generate, from the one or more two-dimensional correlated petrophysical clusters and at least one of the geophysical characteristics, one or more corresponding multi-dimensional clusters of the petrophysical data points and the geophysical data points, wherein individual multi-dimensional clusters of the petrophysical data points and the geophysical data points corresponding to a facies type;
• and
• store, in a facies database located in the data store, cluster centers for at least one of the one or more multi-dimensional clusters of the petrophysical data points and the geophysical data points, wherein the cluster centers that are stored enables identification of facies type based on the seismic signal analysis.
