Abstract: A well completion arrangement and method is for removing at least a portion of a line running in an annulus between a tubing and a casing in a well. The arrangement comprises at least two clamping means spaced apart in the longitudinal direction of the tubing and fixed thereto, the clamping means being configured for fixing the line with respect to tubing, a splitting means for releasing the line from the interval defined by at least an upper clamping means and a lower clamping means of the at least two clamping means, a line manipulator apparatus for activating said release of the line, and a line retrieval apparatus for displacing into the tubing the portion of the line from said interval, thereby removing the line from the annulus.

Abstract: The present invention relates to an apparatus and a method for collecting debris in a wellbore.

Abstract: A downhole electrical energy generating device and a method for transforming energy from a fluid flow passing the device are described. A vibrating assembly is influenced by the fluid flow to oscillate, the vibrating assembly including an elongated body having a longitudinal axis being arranged non-parallel with the fluid flow, a stiff body connecting the elongated body to a portion of the device located downstream of said elongated body; at least one energy harvester influenced by the vibrating assembly, wherein the energy generating device is provided with means for influencing the oscillation frequency of the vibrating assembly.

Abstract: The present disclosure relates to a downhole electrical energy generating device (105) and a method for transforming energy from a fluid flow (107) passing the device (105), including: at least one vibrating assembly (250) influenced by the fluid flow (107) to oscillate, the vibrating assembly (250) including an elongated body (206) having a longitudinal axis being arranged non-parallel with the fluid flow (107), a stiff body (205) connecting the elongated body (206) to a portion of the device located downstream of said elongated body (206); at least one energy harvester (203) influenced by the vibrating assembly (250), wherein the energy generating device (105) is provided with means (204) for influencing the oscillation frequency of the vibrating assembly (250).

Abstract: The disclosure relates to a method for controlling a well barrier (401, 1002) arranged so as to be able to be inserted into a well for allowing a first well zone to be separated from a second well zone by means of a sealing element (409, 903, 1006,), wherein the method includes setting a pressurized fluid in communication with an activating element (905, 906; 1004, 1005) by selectively controlling an opening device (913, 914, 915), and wherein the activating element (905, 906; 1004, 1005) influences opening of the sealing element (409, 903, 1006) to provide communication between said first and second well zones, wherein the method further comprises the step of influencing the pressurized fluid supplied to the activating element (905, 906; 1004, 1005) by the well pressure upstream or downstream of the sealing element (409, 903, 1006). The disclosure also relates to a well barrier (401, 1002) for execution of the method.

Abstract: The present disclosure relates to a device and a method for isolating a section of a wellbore, the device including a straddle packer (1) and associated systems (100, 10) for selectively setting of at least one upper packer element (2), at least one lower packer element (3) and at least one anchoring device (4) of the straddle packer (1), wherein at least one setting element (10) of the straddle packer (1) is operated independent from other setting elements (100).

Abstract: Device for a tool string (2) for insertion in a well, the tool string (2) being provided with a brake nose (1).
