Abstract
A gas and solids separation system is disclosed to separate gas and solids in a subterranean wellbore thereby preventing the gas and solids from interfering with down-hole equipment. The system includes shrouds and diverters that directs the gas away from the intake of the down-hole artificial lift equipment and also utilizes solids collection chambers and shields which separate and trap solids.
Claims15
A separation system for use in a wellbore extending from the surface to a reservoir having reservoir fluids, and the wellbore containing:
- a casing disposed in the wellbore;
- a tubular string disposed in the casing;
- a casing annular sealing device disposed in the casing and sealingly engaged to the tubular string to form an annular barrier for a casing annulus between the casing and the tubular string;
- and
- a shield disposed around the tubular string, above the casing annular sealing device, and dimensioned to substantially cover a surface of the casing annular sealing device and to substantially extend from the tubular string to the casing, wherein the shield is open at the top and comprises a circumferential side raised to define a volume above the shield;
- wherein one or more openings are disposed in a wall of the tubular string above the casing annular sealing device, and wherein none of the one or more openings are between the shield and the casing annular sealing device.
A separator system for use in a wellbore extending from a surface to a subterranean reservoir, the system comprising:
- a casing disposed in the wellbore;
- a tubular string extending into the casing;
- a first solids collection annular sealing device disposed in the tubular string;
- and
- a first solids collection device disposed in the tubular string and connected to the first solids collection annular sealing device, the first solids collection device comprising:
- a first inner tubular connected to the first solids collection annular sealing device, wherein the first inner tubular has one or more openings;
- a first solids collection annulus formed by the first inner tubular and the tubular string, wherein the first solids collection annular sealing device forms an annular seal between the tubular string and the first inner tubular;
- a first cover disposed on an end of the first inner tubular opposite the first solids collection annular sealing device above the one or more openings in the first inner tubular, wherein the first cover is configured to redirect flow out of the one or more openings in the first inner tubular;
- a fluid displacement device disposed in the tubular string above the first solids collection device;
- a casing annular sealing device disposed in the casing and sealingly engaged to the tubular string and forming an annular barrier in a casing annulus between the casing and the tubular string;
- and
- a shield disposed around the tubular string, above the casing annular sealing device and below the one or more openings in tubular string above the flow blocking device, wherein the shield is dimensioned to substantially cover a surface of the casing annular sealing device.
