Abstract
The disclosed downhole gas and solids separator includes a suspended helical flighting member for efficient downhole separation of both gases and solids from a hydrocarbon production stream. Centrifugal force, provided by the flighting member, accelerates the coalescence of like materials to enhance separation of both gases and solids within the separator. Centrifugal force urges solids to the outer wall of the separator and gases toward the center, where passageways are designed to allow solids to efficiently migrate toward and accumulate at the bottom of the separator while simultaneously allowing gases to efficiently rise out of the separator device.
