Abstract
A downhole separation tool utilizes a downhole separation chamber with a series of fluid regulators responsive to a formation fluid and constituent components for separating desirable formation yields from less desirable yields prior to lifting the fluids to the surface. The separation chamber has an input for the formation fluid, a production output, and a disposal output, in a tree arrangement according to the density order of the fluids in the separation chamber. An input flow regulator is coupled to the separation chamber input, a production regulator is coupled to the production output, and a disposal regulator is coupled to the disposal output.
Each of the regulators is responsive to a fluid density of the formation fluid, first constituent and remainder constituent, to regulate the flow of the respective fluid.
Each of the regulators is responsive to a fluid density of the formation fluid, first constituent and remainder constituent, to regulate the flow of the respective fluid.
