摘要： To determine a position of an object in a positioning network associated with a marine survey arrangement, images of targets (208,210) on the object (200) in the positioning network are captured with a plurality of cameras (110,112). Based on known positions of the plurality of cameras and known separation between the targets, positions of the targets are computed by processing the images. A position of the object is derived based on the positions of the targets.

摘要： A GPS-based underwater cable positioning system for use in determining the shape and position of hydrophone streamers towed underwater behind survey vessels involved in marine seismic prospecting. The system includes a plurality of surface units towed behind the vessel. Each surface unit includes a GPS receiver to receive radio frequency GPS signals and to determine its positions. Each surface unit also has an acoustic transmitter to transmit an acoustic message signal representing its position and an optional time stamp into the water. Acoustic receiver units, attached spaced apart locations along one or more streamer cables, each include an acoustic receiver to receive the acoustic message signals from the surface units and to determine its position from the message signals. To augment the message signals from the surface units at locations distant from the surface units, acoustic transceiver units may be used. The acoustic transceiver units are attached to the streamer cables at ranges between the surface units and distant acoustic receiver units. The acoustic transceiver units each include an acoustic receiver that performs as the receivers in the acoustic receiver units and an acoustic transmitter to transmit acoustic message signals representing its position and an optional time stamp into the water to be received by the acoustic receiver units. In this way, the positions and shapes of towed streamer cables can be determined.

摘要： The invention provides a method of determining the orientation of a seismic receiver (4,6) from seismic data acquired at the receiver (4,6). The determined orientation can be taken into account in subsequent analysis of the seismic data. This avoids inaccuracies that can occur if the receiver orientation is estimated. In a preferred embodiment the horizontal spatial derivatives of the pressure measured at the receiver are used in the determination of the orientation of the receiver. These may be calculated on either the source side or the receiver side. These are combined with horizontal components of the particle displacement, velocity or acceleration (or a higher time-derivative of the particle displacement). Alternatively, horizontal spatial derivatives of the particle displacement measured at the receiver may be used in place of the horizontal spatial derivatives of the pressure. The invention also provides a seismic receiver (6) having three or more closely-spaced, non-collinear pressure sensors (8,9,10). The provision of three or more pressure sensors enables the horizontal spatial derivatives of the pressure to be determined accurately.

摘要： The invention relates to a method for determining ocean current using geophysical data acquisition means which are on board a ship, said ship towing at least one streamer which is equipped with at least one traction sensor and position measuring means. The invention is characterised in that it comprises the following steps, consisting in: collecting the measurements from said traction sensor, collecting the measurements from said position measuring means, repeatedly calculating a current vector that is representative of the real current by repeating the following operations using a given sampling time step: calculating simulated traction and streamer positioning data for numerous simulation input current vectors, comparing the simulated data to real measurements taken by said traction and position measuring means for each simulation input current vector. The invention also relates to a device used to carry out one such method.

摘要： Method for determining the geometry of a seismic wave emission device comprising a plurality of seismic sources (S11, S12, S21, etc.) towed by a ship (1) with different transverse and longitudinal offsets. It comprises the isolated triggering of each of the sources (S11, S12, S21, etc.), the detection of acoustic waves coming therefrom by means of proximity sensors (C) arranged at known distances from other sources and optionally from the ship or from a seismic flute, and the recording of detecting signals by means of an acquisition system on board the ship (1). After various corrections of the distances and various processings performed on the signals, parameters (propagation time, phase shiftings) representative of intersource distances are determined and, consequently, the relative coordinates of the sources with respect to each other and their positions with respect to other points. The previous measurements are completed by other measurements related to the immersion depth of different sources. Application to ocean seismic prospection.

摘要： Procédé et dispositif pour la détermination par télémétrie acoustique de la position d'objets immergés (2, 5) par rapport à un navire pourvu d'une base de repérage fixée à celui-ci comportant deux ensembles d'émission-réception acoustique (ER₁, ER₂), et d'une base de repérage remorquée comportant deux autres ensembles (ER₃, ER₄) déportés latéralement par rapport à la trajectoire du navire.
On procède successivement à deux cycles de mesure. Le premier consiste à déterminer par télémétrie acoustique, la position de la base de repérage remorquée par rapport à la base fixe. Le second consiste, toujours par télémétrie acoustique, à déterminer la position des objets remorqués par rapport à la base mobile. On détermine alors les coordonnées de tous les objets remorqués relativement au navire.
Application à la détermination de la géométrie d'un ensemble d'émission sismique multi-sources et d'un dispositif de réception.

摘要： Systems and methods of detecting marine seismic survey parameters are provided. A data processing system can obtain seismic data from seismic data acquisition units disposed on a seabed responsive to an acoustic signal propagated from an acoustic source through a water column. The data processing system can determine from the seismic data, a direct arrival time for the acoustic signal at each of the plurality of seismic data acquisition units, and can obtain an estimated depth value of each of the plurality of seismic data acquisition units and an estimated water column transit velocity of the acoustic signal. The data processing system can apply a depth model and a water column transit velocity model to the estimated depth value and to the estimated water column transit velocity determine an updated depth value and an updated water column transit velocity for each of the plurality of seismic data acquisition units.
