Downhole Separation Efficiency Technology to Produce Wells Through a Dual Completion

摘要

Systems and methods for producing hydrocarbons from a subterranean well include a fluid production tubular and a gas production tubular extending separately into the well. An electrical submersible pump is in fluid communication with the fluid production tubular. A cyclone separator is within the well. The cyclone separator has a rotating screw with thread surfaces open to an inner diameter surface of the well. The rotating screw is positioned between a lower end of the gas production tubular and the electrical submersible pump. The thread surfaces are angled to direct a liquid stream axially downward and radially outward towards the inner diameter surface of the well. A central passage extends through the rotating screw and is oriented to direct a gas stream towards the lower end of the gas production tubular.
