  • Patent number: 9840905
    Abstract: A method and apparatus for determining the location of a material located behind an obstruction. A plurality of acoustic resonators (6) having a known resonant frequency are dispersed in the material (3), the material to be located on a first side of the obstruction (2). An instrument (5) is provided at an opposite side of the obstruction to the material. The instrument emits an acoustic signal and measures a response. If the resonant frequency is detected, it is determined that the material is located substantially adjacent to the instrument. The apparatus may be used for determining the height of cement slurry located between a well casing wall and a borehole.

  • Patent number: 7882892
    Abstract: Well for production of hydrocarbons, comprising a hole drilled down into an underground, a casing fastened to the hole wall, a production pipe that extends into the casing from the surface and down to a hydrocarbon-containing zone, a hanger on the surface in an upper end of the well, in which hanger the production pipe and casing are hung up and electrically short-circuited, and a packer arranged sealingly and electrically short-circuiting in the annulus between the production pipe and the casing, in or close to a lower end of the well, distinguished in that the well further comprises: a primary coil arranged concentrically about the production pipe, a secondary coil arranged concentrically about the production pipe, a load connected to the secondary coil, and an alternating current generator/signal unit connected to the primary coil.

  • Patent number: 5747754
    Abstract: Method and apparatus for carrying out seismic survey includes a plurality of spaced apart seismic detecting sensors each having a geophone unit for detecting seismic activities. The sensors are linked serially with a cable. One end of each geophone unit is flexibly linked to a carrier frame so that the geophone units pivotally move freely relative to the carrier frames. The cable passes through the carrier frames so that the carrier frames are spaced apart serially. Each geophone unit carries a vibrator, a plurality of geophones, a compass, and an inclinometer. The vibrator is positioned on the free end portion of the geophone unit, for embedding the geophone into the ground, while the compass is positioned farthest away from the vibrator. The free pivotal movement of the geophone units enables them to dig into the ground.
