Device and method of enhancing production of hydrocarbons

A device for enhancing the production of hydrocarbons in a wellbore, comprising;

• an outer housing (1) comprising a first internal flow passage (10) and a second internal flow passage (20), wherein the two internal flow passages (10, 20) comprise separate inlets (11,21) and a common outlet (12), wherein the first flow passage (10) is fluidly connected to the inlet (11) of the first flow passage (10) and in fluid communication with a main production flow from a wellbore, wherein the device comprises means for feeding fluid into the second flow passage (20) through the inlet (21) of the second flow passage (20), and wherein the second flow passage (20) is leading to an ejector shaped part (1a) of the flow passages (10, 20), forming an internal outlet (22) of the second flow passage (20) ending in the common outlet (12), where the device and flow passages (10,20) are such configured that a fluid in the second flow passage (20) acts as a driving fluid in the ejector shaped part (1a) in relation to the fluid in the first flow passage (10), and then out through the common outlet (12), characterized in that the device is arranged in a side pocket mandrel and is configured for feeding a fraction of the production flow from the wellbore into the first flow passage (10), and to mix the fraction of the production flow with the fluid from the second flow passage (20) in the device, before the mixed flow is returned to the main production flow, wherein the second flow passage (20) comprises a pressure operated valve device (30), downstream of which valve device (30) the second flow passage (20) leads to the ejector shaped part (1a) of the flow passages (10, 20).
