Oil and Gas Production with Downhole Separation and Reinjection of Gas: 6,564,865


A system for producing a mixed gas-oil stream which contains solid particulates wherein gas is to be separated and compressed downhole in a turbine-driven compressor before the gas is injected into a subterranean formation. The stream is passed through an upstream separator to separate out the particulates which pass through a first and second set of slots into first and second passages, both of which empty into a bypass through the turbine whereby the separated particulates do not contact the rotary vanes of the turbine thereby alleviating the erosive effects of the solids in the produced stream.
