    摘要: To performing positioning of survey equipment, measurements of acoustic signals reflected from at least one boundary of a marine environment are received. The reflected acoustic signals are reflected from the at least one boundary in response to acoustic signaling originated by an acoustic source. A positioning model is updated based on the measurements of the acoustic signals, wherein the positioning model contains information relating to positions of components of a positioning system that includes the acoustic source and acoustic receiver.

    摘要: A method of processing geophysical signals obtained by—monitoring the response of the earth to an source using a plurality of receivers is described including the evaluation of sums or integrals of functions of weighted signal values over a one or multidimensional domain such that the domain is split into a plurality of simplices and the signal values are interpolated across the simplices using a non-linear approximation of the function, the approximation including signals and gradients of the signals, and the evaluated sums or integrals are used to obtain a representation of characteristics of the earth.

    摘要: A technique includes receiving seismic data, which are indicative of pressure measurements and pressure gradient measurements acquired in a seismic survey of at least one subterranean formation. The technique includes modeling an image of the subterranean formation(s) as a function of the pressure measurements and the pressure gradient measurements. The technique includes determining the image based on the modeling.
