Title: Down-hole concentric chamber gas separator and method

Abstract

A down-hole separator is described, comprising: a first tube; a second tube, having a smaller diameter than the first tube and being disposed within the first tube, the second tube having an inlet end and an outlet end, the outlet end being turned at an angle relative to a longitudinal axis of the second tube and passing through a side wall of the first tube, and the inlet end passing sealingly through the second end of the first tube whereby the second end of the first tube is closed, the first tube having perforations at a point below the outlet end of the second tube wherein the first tube further includes an upper joint member having an aperture in which the outlet end of the second tube is mounted, a central tubular section attached to the upper joint member, and a lower joint member, attached to the central tubular section, the lower joint member having a reduced inside diameter whereby sealing connection with the inlet end of the second tube is provided, the perforations of the first tube being located in the lower joint member. A method is also described for separating a down-hole flow of oil and gas, comprisingmore » the steps of: disposing a down-hole separator at a bottom end of a tubing string at a desired distance from a pump contained in the tubing string, the separator comprising a first tube, having a first end and a second end, a second tube, having a smaller diameter than the first tube and being disposed within the first tube, the second tube having an inlet end and an outlet end, the outlet end being turned at an angle relative to a longitudinal axis of the second tube and passing through a side wall of the first tube, and the inlet end passing sealingly through the second end of the first tube, the first tube having perforations at a point below the outlet end of the second tube; selecting the desired distance to provide a desired pressure differential at the perforations of the first tube; and passing the flow through the down-hole separator.« less
