Abstract: Various implementations directed to determining three-dimensional (3D) rock properties using cross well seismic are provided. In one implementation, a method may include receiving 3D seismic data acquired in a seismic survey of a region of interest. The method may also include receiving cross well seismic data acquired in a cross well seismic survey of the region of interest. The method may further include determining a first set of rock properties of the region of interest based on the cross well seismic data. The method may additionally include determining one or more variograms based on the first set of rock properties. The method may also include determining one or more 3D rock properties of the region of interest based on the one or more variograms and the 3D seismic data.

Abstract: A method for evaluating portions of a reservoir includes classifying producing reservoir portions in the reservoir into multiple classifications based on production data associated with the producing reservoir portions. Each classification corresponds to a range of the production data. The method further includes generating a correlation between the classifications of the producing reservoir portions to a petrophysical property and elastic property of the subterranean formation, generating, based on the correlation, a spatial distribution function of reservoir quality to represent predicted classifications as a function of physical locations in the reservoir, and evaluating, using the spatial distribution function, a physical location in the reservoir for reservoir quality.
