The disclosure presents processes to locate one or more quantum gravimeters at a hydrocarbon well site, with at least one quantum gravimeter at a surface location. One or more additional gravimeters, whether quantum gravimeters or non-quantum gravimeters, can be located downhole a wellbore of the well site. Gravitational data collected from various gravimeters can be analyzed to produce analyzed gravitational parameters and subterranean formation parameters.
