  • Patent number: 11085261
    Abstract: A well logging assembly adapted to collect data from the well, comprises a downhole locomotive to move a downhole portion of the logging assembly into the well, a power conduit to supply power from the surface to the downhole portion and a data conduit to transmit data from the downhole portion to the surface. The power conduit comprises a single electrical conductor to send electrical current to the downhole portion from a power supply at the surface. The downhole portion comprises an electrical contact exposed to the well for transmission of the return path for the electrical current to the surface.

  • Patent number: 8944170
    Abstract: A method for completing a wellbore having a plurality of stimulation valves disposed therein at longitudinally spaced apart locations includes moving a spoolable rod into the wellbore. The rod includes a plurality of spaced apart sensors therein. At least one valve operating dart is applied to an exterior of the spoolable rod. The dart is configured to engage a selected one of the stimulation valves. A position of the at least one dart is estimated during pumping of fluid into the wellbore by measuring output of the sensors in the rod.

  • Patent number: 8434515
    Abstract: The present invention relates to a sleeve valve (1), which sleeve valve (1) can be used offshore or onshore to control the fluid flow between a hydrocarbon reservoir and a tubing in a well in the hydrocarbon reservoir. The sleeve valve (1) comprises an outer and an inner sleeve (2, 3) which are coaxially and rotatably arranged relative to one another, wherein in each of the sleeves (2, 3) there is provided at least one through opening (4, 18). The sleeves (2, 3) are rotated relative to one another with the aid of a suitable device, so that they can selectively be brought into an open, closed or other positions therebetween so as thereby to be able to control the fluid flow through the sleeve valve (1).
