Abstract: Techniques involve determining the conductivity profile of a formation from a well between a surface location and a borehole location. The method involves placing a first sensor at the surface location, a second sensor located at the borehole location, obtaining a first signal by detecting Schumann resonances from the electric field occurring at the first location, obtaining a second signal by detecting Schumann resonances from the electric field occurring at the second location with the second sensor; and combining the first and the second signal to determine the conductivity profile of the formation between the first location and the second location.

Abstract: A technique generates seismic data that may be analyzed. A combination sensor is operated and deployed in a borehole to obtain orientation data, such as data related to the local magnetic field and a log of the magnetic field direction in the borehole. Following the combination sensor, at least one multi-component seismic source is deployed downhole into the borehole. The at least one multi-component seismic source comprises sensors, such as an inclinometer and a magnetometer. Data from the combination sensor and from the at least one multi-component seismic source is processed to determine an absolute orientation of the at least one multi-component seismic source.

Abstract: Systems and methods for imaging properties of subterranean formations (136) in a wellbore (106) include a formation sensor (120, 200) for collecting currents (304A, 304B) injected into the subterranean formations (139) and a formation imaging unit (118). The formation imaging unit (118) includes a current management unit for collecting data from the currents injected into the subterranean formations (136) and a formation data unit (116) for determining at least one formation parameter from the collected data. The formation imaging unit (118) also includes an inversion unit for determining at least one formation property by inverting the at least one formation parameter. The inversion unit is suitable for generating an inverted standoff image and an inverted permittivity image for comparison with a composite image of the formation imaging unit.

Abstract: Systems and methods are provided for determining a property, e.g., density, of a geological formation based on Einstein's theory of gravitation. A gravitational potential difference is determined between two positions of the geological formation by measuring a frequency shift of a radiation travelling from a source to an absorber of a differential gravimeter. The gravitational potential difference determined can be converted to a density of the geological formation, e.g., based on a concentric spherical shell model. The systems can be a part of a downhole tool.

Abstract: Systems and methods are provided for determining a property, e.g., density, of a geological formation based on Einstein's theory of gravitation. A tandem-structured gravimeter uses two gamma radiations emitted to two directions to determine a gravitational potential difference between two positions of the geological formation. The gravimeter can be a part of a downhole tool. The gravitational potential difference determined can be used to determine the property of the geological formation.

Abstract: Techniques involve determining the frequency-dependent dielectric permittivity spectrum of a rock sample. Determining the frequency-dependent dielectric permittivity may involve defining a series of electromagnetic measurement data having at least a measurement at a frequency from which a substantially frequency-independent value of dielectric permittivity ε∞ can be obtained. The electromagnetic measurement data also includes measurements at different frequencies from which values for frequency-dependent dielectric permittivity εrock (f) can be obtained. Using these measurements, the frequency-dependent spectrum of the sample may be determined.

Abstract: Techniques involve determining the frequency-dependent dielectric permittivity spectrum of a rock sample. Determining the frequency-dependent dielectric permittivity may involve defining a series of electromagnetic measurement data having at least a measurement at a frequency from which a substantially frequency-independent value of dielectric permittivity ∈∞ can be obtained. The electromagnetic measurement data also includes measurements at different frequencies from which values for frequency-dependent dielectric permittivity ∈rock (f) can be obtained. Using these measurements, the frequency-dependent spectrum of the sample may be determined.
