    Abstract: The transducer comprises for example a block (1) of sensitive elements such as piled piezoelectric disks held up by a stud bolt between two ferrules and a shell (8) all in one piece, that is arranged around the piling with a concave central part (8A) extended on either side by a solid cylindrical part (8 B, 8 C). Two sleeves are arranged at the two opposite ends of the transducer and elastic elements (14) for decoupling them in relation to the vibrating block (1) are interposed. A flexible housing (18) can be placed around the shell (8) so as to insulate from the outside environment the inner volume of the transducer that can be filled with a fluid such as oil. Connecting means allow the vibrating block to be connected to an exciting voltage source. The transducer can be used for the emission of vibrations at sea or in wells and notably petroleum or gas wells for example.

    Abstract: A process for installing seismic sensors inside a petroleum production well equipped with a cemented casing involves arranging the seismic sensors along an outer surface of the casing before being descended into a drilled well and cementing a ring-shaped space between the casing and the well so as to acoustically connect the sensors to geological formations. The sensors and transmission cables which link them to the surface are secured to centering devices guiding the descent of the casing or to the casing outer wall, possibly by means of a coating of damping material. The sensors may be inserted into sleeves secured outside the casing.

    Abstract: A VSP or reversed VSP type seismic prospecting method according to the invention allows disturbances contained in seismic recordings produced by tube waves propagating along wells and refracted in zones close to the surface to be minimized. The method disperses a gas under pressure, having preferably a high compressibility, capable of absorbing these tube waves. The gas may be generated by an explosive chemical reaction set off in situ, at a certain depth of the well (which may constitute the seismic wave source). The method has an application for seismic prospecting or drilling noise monitoring.

    Abstract: A textile backing with a decorative weft is manufactured by raising at least one bonding needle across the warp yarn lap of the textile backing, the bonding needle being used to form a locking mesh having a number of loops; retracting the needles under the textile backing; inserting a decorative weft at right angles to the warp yarns; simultaneously raising and shifting the needles and shifting the locking mesh yam in a circular arc movement using binding guides in order to twill the path of the bonding needle, thereby forming a locking mesh for retaining the decorative weft; displacing the binding guides in translation at a top dead center position for flattening the decorative weft yam against the needle; lowering the bonding needles, drawing the mesh-forming yarn, and creating a loop of locking mesh yarn which encloses the decorative weft; and re-shifting the guides in translation at bottom dead center position in preparation for a new cycle.

    Abstract: The mobile seismic system according to the invention is made up by interconnecting reception sections (T1) and of anchoring sections (T2), and possibly emission sections, the assembly being suspended in the well by means of an electro-carrying cable (3). The first sections (T1), which are filled with liquid, are delimited at least partly by a wall transparent to acoustic waves. They contain each one or several hydrophones and an electronic module of acquisition of the signals picked up. The second sections (T2) comprise a body provided with retractable anchoring means (13) and with motor means, either autonomous, or connected, by a hydraulic line running along the reception system, to common motor means located preferably in a lower section so as to be used as a ballast weight. The reception system may be continuous or made up of several parts connected to each other by electric or electro-hydraulic linking means. The system is suitable for seismic prospecting in wells for example.
