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.

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.

Abstract: A method for sealing a conduit in a spoolable wellbore intervention rod includes exposing an interior of the conduit at a location proximate the earth's surface while the spoolable rod is deployed in a wellbore. A curable sealing compound is introduced into the exposed interior of the conduit and the compound is allowed to cure.

Abstract: This application is directed toward a rod (10) suitable for being inserted into a deviated wellbore (1) in connection with completion operations or intervention operations in a production well or an injection well related to the oil and gas or geothermal industries and a method of manufacturing the same, the rod (10) including a leading portion (10L) and a trailing portion (10T), wherein the rod (10) includes an outer structure (16) capable for holding a filler material (14) influencing the density of the rod (10), and that the density of the rod (10) at the leading portion (10L) is less than the density of at least parts of the trailing portion (10T).

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).

Abstract: This invention describes a conveyor tube for use in installing or replacing a well tool in a producing well, wherein the well tool is fed into the conveyor tube which at least runs between a valve tree and at least one receiving unit in the well, and wherein the conveyor tube is installed on the outside of and in fluid communication with a production tube in the well. A method for using same is also described.

Abstract: A device for use in the selective movement of a well tool in or through at least a portion of a pipe string. The portion of the pipe string being provided with a plurality of electromagnets which are arranged to produce a magnetic field in order to move the well tool within the portion of the pipe string by means of magnetic influence on the well tool. A method for selective movement of a well tool in or through at least a portion of a pipe string.

Abstract: An electrically-enabled semi-stiff wellbore rod and guide nose system is provided, the system including at least one electrical cable disposed in a semi stiff wellbore intervention rod, a termination housing having one end connected to the end of the rod, the termination housing containing fiber optic sensors and the at least one electrical cable, a crossover connected to the other end of the termination housing, a ported coupling connected to the end of the crossover on one end of the ported coupling and having a lower termination for connection to devices on the other end of the ported coupling, where the at least one electrical cable extends through the interior of the crossover from the termination housing and to the ported coupling, one or several pressure-tight tubing(s) surrounding the at least one electrical cable in the interior of the crossover, where the at least one electrical cable is not in pressure communication with the interior of the interior of the crossover, the at least one electrical cab

Abstract: An apparatus (3) for use when gathering parameters from a well flow in a petroleum well (1) in order to be able to evaluate the flow and productivity or injectivity of the well is described, the apparatus (3) including: —a semi-rigid rod (5) arranged in a manner allowing it to sense the temperature profile of the well (1); —at least two mutually spaced-apart measuring devices and/or fluid phase indicators (9) attached to the semi-rigid rod (5); and —at least one pressure sensor (11) arranged in a manner allowing it to sense pressure in the well (1), whereby the amounts of water, oil and gas from one or more formation sections may be quantified. A method of using the apparatus is also described.

Abstract: A method for demodulating signals from a dispersive, white light interferometer includes generating test interferometry spectra from an interferometer forming part of a sensor for various values of interferometer sensor optical path length. The various test spectra are correlated to a measured spectrum from the sensor to generate a correlation function. The sensor optical path length resulting in the correlation function value reaching a maximum is selected as the optical path length.
