摘要： A shear wave generator for use subsea, including an excitation unit that is fastened to a top plate; a skirt, the upper end of which is fastened sealingly to the top plate and extending downward to an open lower end of the skirt, such that the top plate and skirt form a closed space by lowering to the seabed; and a pump arranged with fluid communication between the space and the surroundings, such that by pumping water out of the space, an underpressure is formed acting to suck the shear wave generator fixedly to and partly into the seabed, and by pumping water into the space, an overpressure is formed acting to lift the shear wave generator up from the seabed. The shear wave generator is distinguished in that the skirt is formed with a larger outer diameter or width at its upper end than at its lower end.

摘要： A seismic shear wave generator comprising a seismic wave source (3) arranged on a base plate (11) arranged for being placed at the seabed, and a coupling device (1) arranged for coupling the wave source (3) mechanically to the seabed in order for shear waves to be transmitted to the seabed. The novelty of the invention is as follows: a cylindrical skirt (1) closely arranged along the base plate's (11) circumference and extending down from the underside of the base plate (11), and open downwards, and a pump device (2) arranged for pumping water respectably out of, and into, the skirt (1) and form vacuum or overpressure, respectively, in a closed cavity formed by the skirt (1) and the base plate (11) and the seabed (1) is lowered onto the seabed. By means of the device mentioned above the shear wave generator may be suctioned fixed to the sea bed and thus transfer shear waves via the skirt (1) to the seabed.

摘要： A method of providing seismic data (such as marine seismic data). A seismic source is actuated at a plurality of source locations (S2, S4). For each source location, a multicomponent seismic measurement is performed at least one receiver location (S3). A reconstructing method is applied to each multicomponent measurement to obtain additional data corresponding to source locations additional to the source locations at which the source was actuated (S5). The additional data are output and/or used (S6).

摘要： A method for monitoring a high-resistivity reservoir rock formation (2) below one or more less resistive formations (3). The method includes transmitting an electromagnetic signal (S) propagating from near a seafloor or land surface (1) by means of an electromagnetic transmitter (5) powered by a voltage signal generator (G). The electromagnetic signal (S) propagates from the seafloor (1) and is guided along a conductive string (7) to the high-resistive formation (2), and propagates as a guided-wave electromagnetic signal (S2) at a relatively higher speed (V2) inside the high-resistivity formation (2) than a propagation speed (V3) in the less resistive formations (3). The guided-wave electromagnetic signal (S2) gives rise to an upward refracting electromagnetic signal (R3) having the relatively lower propagation speed (V3) in the less resistive formations (3) and having an exit angle nearer to the normal (N) to the interface between the high-resistivity formation (2) and the lower-resistivity formation (3), and gives rise to a steeply rising refraction wave front (F3). The refracted electromagnetic wave front (F3) includes refracted electromagnetic signals (R3) detected along an array of sensor antennas (6a, 6b, 6c, . . . , 6k, . . . , 6n) positioned along the seafloor. The array having a direction away from the transmitter (5).
