11. A method for restoring, maintaining, or increasing oil or gas productivity of a geological formation via locating maximum hydrodynamic connectivity between wells located in said geological formation, comprising:
positioning a first acoustic/ultrasonic device in a first well located within the geological formation,
positioning one or more additional acoustic/ultrasonic devices in one or more additional wells located within the geological formation,
emitting one or more signals in one or more ranges, said emitting being performed by said first device, said one or more signals comprising both ultrasonic and acoustic signals,
wherein the one or more signals comprises a Fourier transformation of a periodic function,
receiving of said one or more signals, said receiving being performed by a receiver located on the one or more additional devices,
standardizing said one or more signals received, said standardizing being based at least in part on a distance between said one or more additional wells and said first well, thus forming one or more standardized figures representing each signal received, and
determining a value representing a likelihood of hydrodynamic connectivity between said first well and said second well, said value being based on a comparison of signals,
wherein the determining step accounts for an absorption of ultrasound or an absorption of an acoustic signal.
