The method may additionally include calculating an actual travel difference between the acoustic positioning source and the acoustic positioning receiver based on the acoustic positioning signal. The method may further include comparing the actual travel difference to the expected travel difference. The method may also include identifying whether the acoustic positioning signal is a reflected positioning signal based on the comparison.

摘要： A seismic sensor device includes an elongated housing for placement at least partially into an earth surface. A plurality of particle motion sensors are contained in the elongated housing to measure translational data in a first direction, where plural pairs of the particle motion sensors are spaced apart along a second, different direction along a longitudinal axis of the elongated housing. A communication interface communicates the measured translational data to a computer system configured to compute a gradient based on respective differences of the measured translational data of the corresponding plural pairs of the particle motion sensors, and compute one or more of rotation data and divergence data using the gradient.

摘要： A method for processing seismic data. The method includes performing a plurality of stochastic simulations for one or more rock model parameters to generate one or more anisotropic parameters for a subsurface area of the earth.

摘要： A method and system for deploying seismic tows, such as seismic streamers, from a common carrier rope for conducting marine seismic surveys. The deployment system generally comprises a carrier rope having at least one deflector urging the carrier rope laterally relative to the towing vessel and seismic tows that are independently moveable along the deployed carrier rope to desired locations from which to be deployed. The carrier rope may be deployed from the tow vessel into the water prior to deploying the seismic streamer(s) into the water.

摘要： Methods and systems for efficiently acquiring towed streamer marine seismic data are described. One method and system comprises positioning a plurality of source-only tow vessels and one or more source-streamer tow vessels to acquire a wide- and/or full-azimuth seismic survey without need for the spread to repeat a path once traversed. Another method and system allows surveying a sub-sea geologic feature using a marine seismic spread, the spread smartly negotiating at least one turn during the surveying, and shooting and recording during the turn. This abstract is provided to comply with the rules requiring an abstract, allowing a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

摘要： A method for processing seismic data. The method includes receiving the seismic data acquired at two or more sensors on a towed marine survey and regularizing the received seismic data into a spatial domain. After regularizing the seismic data, the method includes classifying the regularized seismic data below and equal to a predetermined frequency as low-frequency seismic data. The method then calculates a set of low-frequency Green's functions using interferometry on the low-frequency seismic data described above. The method then processes high-frequency seismic data of the seismic data to create a set of high-frequency Green's functions at one or more source locations of the towed marine survey. After creating the set of high-frequency Green's functions, the method merges the set of low-frequency Green's functions and the set of high-frequency Green's functions to create a set of broad-band Green's functions at the source locations.
