Abstract: A technique facilitates improved transmission of signals in subsea measurement operations. The improved transmission may involve use of various signal amplifiers. According to an embodiment, a distributed measurement system comprises a surface system coupled with a subsea system via an umbilical. The surface system may comprise a distributed interrogator combined with a surface circulator and pump module. Additionally, the subsea system may comprise a remote circulator module having, for example, at least one remote optical amplifier and which may be coupled with a distributed sensor. The umbilical may utilize an outgoing optical fiber and a returning optical fiber.

Abstract: A system includes an acoustic attenuation interface disposed between a first acoustic transmission conduit and a second acoustic transmission conduit. An acoustic signal source acoustically coupled to the first acoustic transmission conduit generates an acoustic signal. An acoustic noise source acoustically coupled to the second acoustic transmission conduit generates an acoustic noise. A first sensor is configured to detect a first composite signal including the acoustic signal after transmission through at least a portion of the first acoustic transmission conduit and an attenuated acoustic noise. A second sensor is configured to detect a second composite signal including the acoustic signal after transmission through at least a portion of the first acoustic transmission conduit and attenuated by the acoustic attenuation interface and the acoustic noise. An acoustic signal processing system is configured to determine a noise-reduced signal from the first composite signal and the second composite signal.

Abstract: Certain embodiments are directed to seismic survey systems for generating S-waves and Love waves for seismic exploration using explosives in inclined holes. The direction in which the inclined hole is drilled controls the azimuthal polarization of the S-waves generated. The explosive needs to be placed tightly into the borehole eliminating fluids from around the charge or alternatively grouted and stemmed to eliminate fluids.

Abstract: A method and downhole tool is provided that uses beamforming to localize acoustic energy at a desired zone-of-interest within a wellbore traversing a subterranean formation. The tool has an array of transmitter elements configured to emit guided mode acoustic signals at variable amplitude and variable time delay, which are individually controlled by an amplitude factor and time delay assigned to respective transmitter elements. A set of amplitude factors and time delays can be assigned to the transmitter elements of the transmitter array such that the transmitter elements produce a focused acoustic beam at the desired zone-of-interest by combination of guided mode acoustic signals transmitted by the transmitter elements.

Abstract: An apparatus comprises a circuitry and an acoustic-capture tile having a surface that is to face an acoustic source that is to emit a first acoustic wave having a first frequency and a second acoustic wave having a second frequency. The acoustic-capture tile comprises a first acoustic-capture subtile electrically coupled to the circuitry, the first acoustic-capture subtile to resonate at the first frequency, wherein the first acoustic-capture subtile is to capture the first acoustic wave and to convert the first acoustic wave into a first electric current in response to resonance at the first frequency. The acoustic-capture tile also comprises a second acoustic-capture subtile electrically coupled to the circuitry, the second acoustic-capture subtile to resonate at the second frequency, wherein the second acoustic-capture subtile is to capture the second acoustic wave and to convert the second acoustic wave into a second electric current in response to resonance at the second frequency.

Abstract: Disclosed are systems and methods for selecting modes and frequencies of interest in a slowness-frequency map of sonic logging information. These include measuring, by a sonic logging tool, sonic data within a borehole, determining a frequency range for a selected mode of the sonic data, determining a slowness range for the selected mode of the sonic data, applying the frequency range and the slowness range to the sonic data to select a subset of data from the sonic data, processing the selected subset of data.
