    摘要: A method of determining an integral of a function over an n-dimensional integration domain from the values of the function at a plurality of discrete data points within the integration domain, comprises partitioning the integration domain into a plurality of k-dimensional simplexes, where k≦n. The function is integrated over each simplex, and the results are summed. The method may be applied in the processing of geophysical data such as, for example, seismic data, where the function is a function of at least the geophysical data. The processed data may then be used to obtain information about the physical properties of the earth's interior.

    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.

    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.
