    Abstract: A method for seismic surveying includes deploying a first seismic energy source at a plurality of locations along a source line. Locations are determined by, (i) setting a shot point at one end of the line, setting a minimum distance between shot points and setting a nominal shot point interval being greater than a Nyquist maximum spacing at a maximum spatial frequency to be evaluated in the subsurface area, (ii) calculating a maximum distance between shot points as a difference between twice the nominal shot point interval and the minimum distance, (iii) dividing a span between the maximum distance and the minimum distance into equally spaced samples, and choosing at random one of the equally spaced samples to calculate a shot point subsequent to the initial shot point; and (iv) setting the calculated shot point as the initial shot point and repeating (ii) and (iii) until the subsequent calculated shot point is within a predetermined distance of an opposed end of the first source line. Seismic receivers are deployed at proximate the subsurface area. The seismic energy source is actuated. Seismic signals are detected in response to energy imparted by the first seismic energy source by the receivers.

    Abstract: It is proposed a method for automatically assigning wireless seismic acquisition units to topographic positions, each wireless seismic acquisition unit includes a satellite navigation system receiver. The method has the following steps, carried out by an assigning device: obtaining topographic locations at which the wireless seismic acquisition units are expected to be laid; obtaining measured positions of the wireless seismic acquisition units, corresponding to or derived from position information provided by the satellite navigation system receivers when the wireless seismic acquisition units are installed on the ground, each near one of the topographic locations; and computing associations, each between one of the wireless seismic acquisition units and one of the topographic positions, as a function of a comparison between the measured positions and the topographic locations.

    Abstract: According to an embodiment, a seismic receiver device is described for use in a borehole surrounded by an ambient material, e.g., rock, mud, etc. The seismic receiver device includes a pressure wave measuring device which is configured to sense pressure changes associated with received seismic waves, a coating layer disposed on the pressure wave measuring device, and an outer layer disposed on the coating layer which is made of a material that is selected to have a bulk modulus number that is substantially similar to a bulk modulus number of the ambient medium. In this way, the acoustic impedance of the device is better matched to the ambient material so that more accurate seismic acquisition may be performed.

    Abstract: Method and retrievable vertical hydrophone cable for collecting seismic data underground. The retrievable vertical hydrophone cable includes an envelope having a first end at which a connector mechanism is provided to close the envelope; plural hydrophones distributed inside the envelope at predetermined positions; and a fluid provided inside the envelope and around the plural hydrophones. The envelope increases its volume when the fluid is pressurized through the connector mechanism.

    Abstract: A fixation releasing device by which a buoyant body and a weight may be securely fixed and the fixed state between the buoyant body and the weight may be readily released, using a simple structure. The fixation releasing device is made from a buoyant body, a weight, and a connection designed to connect the buoyant body and weight. The connection device has a connection structure made from a closed loop member, rotation arms, and connection members. A connection member is engaged with each rotation arm, and rotation of each rotation arm is restrained by the closed loop member, thereby fixing the buoyant body. To release the buoyant body, a trigger mechanism provided at the closed loop member is operated to fusion cut the closed loop member. Then, each rotation arm is rotated, and then the connection member comes out of each rotation arm, thereby releasing the buoyant body.
