1. A method for determining sweet spots in a subterranean formation, the method comprising:
drilling a plurality of wellbores in the subterranean formation using a drill tool;
measuring at least a permeability and a fluid viscosity of each of the plurality of wellbores by lowering a logging tool in each of the plurality of wellbores to collect measurements using the logging tool;
generating petrophysical logs of the plurality of wellbores based on at least the permeability and the fluid viscosity of each of the plurality of wellbores;
calculating a reservoir quality index parameter for each wellbore of the plurality of wellbores based on the permeability and the fluid viscosity of each respective wellbore from the petrophysical logs;
creating a reservoir quality index map using the petrophysical logs;
calculating a linear flow index parameter for each wellbore of the plurality of wellbores based on production data provided by the petrophysical logs;
correlating the reservoir quality index parameter and the linear flow index parameter for each wellbore of the plurality of wellbores to locate sweet spots; and
ranking a basin based on the located sweet spots and the correlated parameters.
