ABSTRACT:
A method and assembly for recovering fluids from, or injecting fluids into, a well having a christmas tree; the fluids typically flow between first and second flowpaths in a continuous path. The assembly may be located within the main bore, or a side passage of the christmas tree. Embodiments of the invention allow the fluids to be fed to a processing apparatus, (e.g. a pump or chemical injection apparatus) for treatment, before being returned to the christmas tree. Optionally, the assembly may include a pump located inside the christmas tree body.
