摘要： In order to perform a passive survey, sensors (5, 8) for obtaining data relating to the structure of the region (1) are deployed on ice bodies (4) which move as a result of natural drift. The sensors (5, 8) are used to obtain data at different locations resulting from movement of the ice bodies (4) with respect to the region (1). The sensors (5, 8) may be seismometers which respond to ambient noise, for example resulting from cracking or colliding of the ice bodies (4, 24).

摘要： Subsurface hydrocarbon reservoir-sized structures are detected or monitored by ambient noise tomography. Interface wave data are recorded for interface waves excited by seismic ambient noise. The data are recorded simultaneously at pairs of locations with the locations of each pair being spaced by less than or equal to a wavelength at the frequencies of interest. The recorded data are processed (3-7) by tomography to obtain group-velocity and/or phase-velocity tomograms, which are inverted to obtain seismic parameters values, such as seismic velocity. The seismic parameters may then be used to form a geological model (8) of a subsurface region of interest.

摘要： A passive method is provided for exploring a region below the surface of the earth. The method comprises using a single sensor located in turn at a plurality of locations to obtain seismic data obtained by recording ambient seismic interface waves in a frequency range whose lower limit is greater than OHz, and whose upper limit is less than or equal to substantially 1 Hz. The data are processed (41-44) so as to obtain a measure of the energy in a frequency band within the frequency range. For example, the seismic data may be filtered (41 ) and may be subjected to amplitude normalisation (42) before being transformed (43) into the frequency domain. The energy measure may then be calculated (44) by integrating the spectrum in the frequency domain over a desired frequency range. The resulting calculated energy provides information about the region of the earth being explored.

摘要： A passive method is provided for exploring a region below the surface of the earth. The method comprises using a plurality of sensors (20, 21) to obtain seismic data obtained by recording ambient seismic interface waves in a frequency range whose lower limit is greater than 0Hz, and whose upper limit is less than or equal to substantially 1Hz. The sensors (20, 21) may be sensitive to three orthogonal components. Recordings may be made simultaneously by all sensors (20, 21) and normalisation of data is unnecessary. The sensors (20, 21) may be moved and clean data may be selected. Local dispersion curves may be determined to improve vertical resolution. The data are processed (41-44) so as to obtain a measure of the energy in a frequency band within the frequency range. The energy measure may be calculated (44) by integrating the spectrum in the frequency domain over a desired frequency range. The resulting calculated energy provides information about the region of the earth being explored.
