Patent

CA 2277566

A technique is disclosed for completion of a well, such as an oil and gas production well. A packer is positioned in the well to divide the well into upper and lower zones. The packer has multiple passageways between the upper and lower zones. A pumping system is positioned in the lower zone for displacing wellbore fluids flowing from a production formation. The pumping system may include a liquid/gas separator, and express gas-phase components through one of the passageways and liquid-phase components through another. A conduit conveys the gas-phase components to a desired location. The liquid-phase components are conveyed to a collection location in the annular region surrounding the conduit. The conduit may be used for positioning a chemical injection line within the well, or for receiving a parameter sensing unit. The chemical injection and parameter sensing may be performed independently of gas production, and without interruption of either gas or liquid production.
