Predicting hydraulic fracture treatment uses well log data and core data from one well in a given subsurface region to create a petrophysical properties model for the subsurface region. The petrophysical properties model yields fluid volumes and mineral volumes in any given well passing through the subsurface region using only well log data as inputs. The fluid and mineral volumes are used with dipole sonic data from a second well to create an elastic rock properties model for the given subsurface that yields elastic properties in any well passing through the subsurface region using only well log data and mineral and fluid volumes. For wells in the subsurface having only well log data, the petrophysical properties model and the elastic rock properties model are used with the well log data to predict an amount of recoverable hydrocarbons within wells that will respond to hydraulic fracture treatments.
