A reception device includes a reception unit which receives a composite signal of a received artificial signal representing a signal propagated to the reception device using water as a medium in the transmission artificial signal, and a self-potential propagated to the reception device using water as a medium due to a potential anomaly generated due to submarine resources. A signal processing device includes a signal processing unit which separates the composite signal into the received artificial signal and the self-potential.

Disclosed are methods for locating deposits of mineral resources below the Earth's crust. A period of resonance of 14-day gravitational tides is predicted based on known information about a location. During the period of resonance, element vapor emissions and/or other data are recorded using gas analyzers and/or other devices, which are spread in an array over the location. The vapors and/or other data are recorded for a period of about 3-4 days. The recorded data is analyzed to determine when and where any anomalies exist. By comparing anomalies to control data, the changes can be further extrapolated to obtain more accurate data. After anomalies are detected and analyzed, the locations of deposits comprising mineral resources can be determined and maps of the locations correlating to the surface are generated.

Naturally-occurring, electromagnetic signals generated by interaction of solar wind with earth's magnetosphere adjacent a borehole are measured by an electromagnetic sensor positioned adjacent the borehole in the hydrocarbon-bearing formation. Electromagnetic signals generated within the borehole are measured over a period of time by a borehole sensor positioned within the borehole. The electromagnetic signals change over the period of time due to variations in fluid distributions within the hydrocarbon-bearing formation. Electromagnetic changes to the electromagnetic signals generated within the borehole and to the passive, naturally-occurring electromagnetic signals over the period of time are determined by one or more processors. A computational model of the hydrocarbon-bearing formation is generated based in part on the electromagnetic changes.
