Abstract
A method of producing a side pocket mandrel body () for use in a hydrocarbon well side pocket mandrel assembly, which mandrel body comprises: a first end () displaying a first connection arrangement () for connecting the mandrel body to an up-hole section of a production tubing of the hydrocarbon well, and a second end () displaying a second connection arrangement () for connecting the mandrel body to a down-hole section of the production tubing; a longitudinal, through-going main conduit () for communicating with a central passageway of the production tubing; and a side pocket section () comprising at least one side pocket () for retrievably housing an injection fluid flow control device. The method comprises the steps of: providing a continuous, solid piece of material with the through-going main conduit; in the solid piece of material, forming said at least one side pocket by machining a bore (), displaying an external entrance opening (), into a laterally offset section of the solid piece of material generally parallel to the main conduit such that an internal wall section () of the solid piece of material is brought to separate the main conduit from the machined bore; plugging the entrance opening () of the machined bore with a fluid-tight plug (); providing at least one opening () from an outside of the mandrel body into the at least one side pocket, thereby forming an injection fluid inlet; providing at least one opening in the wall section, thereby forming an injection fluid outlet; and providing the solid piece of material with the first and the second connection arrangements, thereby rendering the mandrel body connectable to the up-hole and down-hole sections of the production tubing.
