Abstract
A device for increasing the production flow in a production tubing, where the production tubing has at least one inlet or port for adding a fluid medium, adds the fluid medium through the at least one inlet or port at an angle α between 90 and 0 degrees with a longitudinal axis of the production tubing. The device further has elements that provide a rotation of the added fluid medium.

Device for increasing the production flow in a production tubing, where the production tubing comprises at least one inlet or port for adding a fluid medium, the fluid medium being added through the at least one inlet at an angle α between 90 and 0 degrees with a longitudinal axis of the production tubing, with an open end of the angle facing upstream, wherein the device further comprises a rotating member provided with impeller blades arranged in an annular chamber between a casing and the production tubing, the annular chamber being formed by a packer system, the annular chamber further being divided in at least two compartments both having a flow of added fluid but in opposite directions, such that the flow direction of the fluid medium is turned in the bottom of the annular chamber, the fluid medium being provided with a rotation relative the production tubing before it is injected into the production tubing through the at least one inlet.
