Abstract
A wellbore fluid production system that is disposable in a wellbore comprising a separator, a pump, a compressor, and a motor. The separator segregates the gas and liquid and delivers the gas to the compressor inlet and the liquid to the pump inlet. The pump pressurizes the liquid for delivery to the surface. The compressor pressurizes the gas for reinjection into the wellbore, injection into another subterranean formation, or for delivery to the surface.
Claims20
A fluid production system for delivering wellbore fluids comprising:
- a gas liquid separator having an inlet configured to receive subterranean wellbore fluid, a gas exit configured to discharge gas from within the fluid from the separator, and a liquid exit configured to discharge liquid within the fluid from the separator;
- a pump having an inlet formed to receive liquid from the liquid exit;
- a compressor having an inlet formed to receive gas from the gas exit;
- and
- a motor mechanically coupled to the separator, pump, and compressor, wherein the system is disposed in a conduit.
A method of producing a two phase gas liquid mixture of wellbore fluid, the method comprising:
- separating the gas and liquid mixture into a substantially mono-phase gas component and a substantially mono-phase liquid component;
- pumping the mono-phase liquid component;
- and
- compressing the mono-phase gas component, wherein the steps of separating, pumping and compressing are performed by a device disposed in a conduit.
A system for pressurizing two phase wellbore fluid flowing into a conduit comprising:
- an electrical motor assembly within the conduit;
- a rotary gas liquid separator in the conduit and mounted to the motor assembly the separator having an inlet, a gas exit, and a liquid exit;
- a centrifugal pump mounted to the separator liquid exit;
- a rotary compressor assembly mounted to the gas exit;
- and
- a gas bypass line extending from the separator gas exit alongside the pump to the compressor.
