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.
