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.

Abstract: Electric interconnecting cables fitted with sealed electric connectors resistant to pressure are most often used to connect electrically together various equipments (1) distant from one another and immersed in a conducting liquid such as may be encountered in wellbores. To avoid this relatively costly solution, a process is proposed, wherein the various equipments (1) are linked together through sealed and empty hydraulic pipes or cables (22), so as to form a common space insulated from the external environment, and the electric linking conductors (25) are passed inside the hydraulic cable circuit constituted thereby.

Abstract: A casing is lowered in a well for production of an underground petroleum deposit. The casing includes a number of tubular sections connected successively to each other by special tubular connectors, at least certain of these being modified, and the casing being cemented in position when installed in the well. These special connectors include housings for one or several sensors and other housings, if necessary, for the electronic acquisition or transmission circuits. The different connectors for the device are interconnected by cables and to an installation on the surface by a multi-line cable for the electrical supply to the electronic modules and transmission of the data acquired. This arrangement permits prewiring of the different connectors, thus simplifying the positioning of the device during operations for equipping the wells.

Abstract: A mixed device for successively generating in the earth, at the same location, longitudinal and shear waves is disclosed. The device comprises in association a target coupled to the earth surface and having a first striking face substantially parallel thereto and at least one second striking face substantially perpendicular to said first striking face. A guide tube is adapted to be positioned above the first striking face and perpendicularly thereto, and a movable weight is slidable in the guide tube and adapted to strike the first striking face. At least one hammer is articulated to a support rigidly secured to the guide tube and adapted to strike one second striking face of the target. Directional coupling means connect the guide tube to the target in such a manner that the weight sliding in the guide tube directly impinges the first striking face, but such that the guide tube is substantially released from the effect of the hammer impact on a second striking face.
