Abstract
A method and system for producing a mixed gas-oil stream through a wellbore wherein at least a portion of the gas is separated from the stream downhole and is compressed (e.g. using a SPARC) before both the compressed gas and the remainder of the stream is brought to the surface through separate flowpaths. The system includes a string of tubing which provides the flowpath for the remainder of the stream while the annulus, formed between the tubing string and the wellbore provides the flowpath for the compressed gas.
