Abstract
A method and apparatus for gas and solids separation from down-hole fluids is disclosed, including particular structural means for forcing the de-gassing of the gaseous liquid, including means for changing the velocity of the gaseous liquid (speed changes on each exit from the tubes owing to the volume difference between the tubes and the chamber), means for changing the direction of the gaseous liquid (owing to the flow changing direction from exiting one set of tubes to travel to the opening to enter the next set of tubes), and means for changing the pressure of the gaseous liquid (owing perhaps in part to evolution of gas upon entering increased volume).
Claims19
An apparatus for separating of gas from a fluid in a wellbore, comprising:
- a first pipe configured to be disposed in a wellbore and define a wellbore annulus between the first pipe and the wellbore;
- a second pipe disposed in the first pipe, an inner annulus defined between the first pipe and the second pipe;
- a plurality of production separation chambers disposed in the first pipe;
- an orifice in an upper portion of each of the plurality of production separation chambers, the orifice configured to open into the wellbore annulus;
- one or more solids management tubes, the one or more solids management tubes having a top open end near a floor or lower portion of one of the production separation chambers and extending downward into a next lower production separation chamber;
- and
- thief jet orifices in the second pipe, each thief jet orifice positioned near a bottom of a respective production separation chamber and opening into the inner annulus,
- wherein the thief jet orifices restrict flow of the fluid to remove gas bubbles from the fluid.
An apparatus for separating of gas from fluids in a wellbore, comprising:
- a first pipe in the wellbore and defining a wellbore annulus between the first pipe and the wellbore;
- a second pipe disposed in the first pipe and defining an inner annulus between the second pipe and the first pipe;
- a plurality of production separation chambers disposed in the first pipe;
- an orifice in an upper portion of each of the plurality of production separation chambers, the orifice opening into the wellbore annulus;
- and
- thief jet orifices in the second pipe, each thief jet orifice positioned near a bottom of a respective production separation chamber and opening into the inner annulus;
- and
- a tube extending through the plurality of production separation chambers, the tube having orifices within the plurality of production separation chambers and an upper opening disposed above the plurality of production separation chambers,
- wherein the thief jet orifices restrict flow of the fluid to remove gas bubbles from the fluid.

- thief jet orifices disposed in the second pipe, each thief jet orifice positioned near a bottom of a respective production separation chamber and opening into the inner annulus;
- and
- a pressure loss chamber above the plurality of production separation chambers, the pressure loss chamber having an opening to the wellbore and having another opening configured to receive gas from one or more of the plurality of production separation chambers;
- and
- wherein each of the thief jet orifices restricts flow of the fluid to remove gas bubbles from the fluid.
