Monitoring of gravitational tides resonances for the purposes of oil and gas geological exploration

The article provides physical backgrounds for using gravitational tides’ resonances as a matter of direct hydrocarbon exploration. It also explains the forecast method to predict the timing of gravitational tides in the Earth’s crust on the basis of graphical addition of normalized curves for main gravitational factors (a distance between the Earth and the Moon, phases of the Moon, barycenter of the Earth-Moon system). The article provides the explanation of geophysical complex for gravitational tides’ resonances monitoring in oil and gas promising areas that includes: low-frequency (from 1.0 to 5.0 Hz) and extra-low-frequency (from 0,1 to 1,0 Hz) seismic explorations, natural impulse electromagnetic field, gas chemical and geochemical monitoring for radon and hydrocarbon gases. It also shows the possibility to establish a registration technology to monitor oil and gas reservoirs reaction to tidal activities.
Materials and methods
However there is no definite academic solution how to predict oceanic tides up to the present times. In recent decades, sea and oceanic tides are also used to generate electricity as for enormous energy potential of these tides. There is no information in academic resources that someone uses gravitational tides in the Earth’s crust for the purposes of oil and gas geological exploration. Physical backgrounds for using gravitational tides’ resonances as a matter of direct hydrocarbon exploration includes: Oil and gas reservoir is a mobile formation fluid in some areas of the Earth crust. Gravitation tides in the Earth’s crust causes daily surface oscillation that limits the reservoir. Due to the fact of a great difference between a reservoir rock compressibility coefficient (first percentage) and an oil and gas fluid (tens and hundreds of percentage), in the fluid oil and gas reservoir during gravitational tides occurs self-induced oscillations on low-frequency (from 1.0 to 5.0 Hz) and extra-low-frequency (from 0,1 to 1,0 Hz) according to shape, size and viscosity of oil and gas reservoir. The amplitude gain in reservoirs during gravitational tides is a basic physical background to establish a new geological exploration
Results
The field experiment proved presented physical backgrounds for exploring oil and gas reservoirs during gravitational tides in different geophysical fields [7].
Сonclusions
Monitoring of geophysical and geochemical fields on the basis of gravitational tide’s resonance energies provides physical backgrounds to establish radically new technology for direct oil and gas exploration, completely different from the existing technologies (like “Anchar”, NSZ, microseisms). Nonetheless, the proposed technology for direct oil and gas exploration on the basis of gravitational tides doesn’t have any drawbacks of already established technologies for "passive" seismic exploration.
