9. A method for producing a well having an annulus completed across a gas reservoir and an oil reservoir, the method comprising:
deploying a gas lift system into the well, the gas lift system comprising:
tubing configured to be a conduit for production fluids having a weight;
an inflow control valve;
a gas-separator compressor turbine device;
at least one sensor fixed to an outlet of the gas-separator compressor turbine device;
a gas lift valve installed within the tubing;
wherein the inflow control valve, the gas-separator compressor turbine device, and
the gas lift valve, are configured to be installed within the tubing;
opening the inflow control valve to allow gas to flow from the gas reservoir into the tubing;
separating the gas from the production fluids using the gas-separator compressor turbine device;
compressing the gas using the gas-separator compressor turbine device;
injecting the gas into the annulus using the gas-separator compressor turbine device;
flowing the gas through the gas lift valve into the tubing;
measuring a volume of gas being injected into the annulus using the at least one sensor;
closing the inflow control valve when a predetermined volume of gas is reached;
mixing the gas and the production fluids to lower the weight of the production fluids; and
flowing the production fluids through the tubing to be produced at a surface location.
