Downhole draw down pump and method

An apparatus for lifting fluids and solids within a wellbore, wherein said wellbore intersects a natural gas deposit having natural gas and wherein said wellbore intersects and extends past the natural gas deposit so that a sump portion of the well bore is formed, the apparatus comprising:

• a first tubular disposed within the wellbore so that a wellbore annulus is formed therein, and wherein said first tubular has a distal end and a proximal end and wherein said wellbore annulus has a fluid level therein;
• an annular nozzle operatively attached to the distal end of said first tubular, and wherein said annular nozzle comprises:
• an annular adapter;
• and, a suction tube that extends from said annular adapter into an inner portion of said first tubular, wherein said suction tube has an inner portion and an outer portion;
• a second tubular concentrically disposed within said first tubular so that a micro annulus is formed therein for injection of a power fluid, and wherein a first end of said second tubular is concentrically positioned about said outer portion of said suction tube so that an annular passage for the power fluid is formed within an inner portion of said second tubular;
• wherein said inner portion of said suction tube has an open end in communication with said sump portion, said open end having an unobstructual circular cross-sectional area to lift the fluids and solids located in said well bore annulus
• and wherein said wellbore annulus is in communication with a gas production line for producing gas from the natural gas deposit once the fluid level within said wellbore annulus is drawn down.

A method of drawing down a fluid column and solids in a wellbore, and wherein said wellbore intersects a natural gas deposit having natural gas, the method comprising:

• providing a first tubular within the wellbore so that a wellbore annulus is formed therein, the first tubing member having an annular nozzle at a first end, and wherein said annular nozzle contains an annular adapter that is connected to a cylindrical suction tube, and wherein said cylindrical suction tube having an inner portion and an outer portion and wherein said inner portion has an unobstructed circular cross-sectional area, and wherein said suction tube extends into an inner portion of said first tubular;
• lowering a second tubular concentrically within said first tubular so that a micro annulus is formed, and wherein a first end of said second tubular is concentrically positioned about said outer portion of said suction tube so that an annular passage if formed;
• injecting a medium into the micro annulus;
• channeling the medium through said annular passage nozzle;
• increasing the velocity of the medium within said annular passage;
• causing an area of low pressure within the unobstructed circular cross-sectional area of the inner portion of said suction tube;
• drawing down the fluid contained within the wellbore annulus into the unobstructed circular cross-sectional area of the inner portion of said suction tube;
• suctioning the solids contained within the well bore annulus into the unobstructed circular cross-sectional area of the inner portion of said suction tube;
• exiting the fluid and solids from the inner portion of said suction tube into an inner portion of the second tubular;
• mixing the fluid and solids with the medium in the inner portion of the second tubular;
• discharging the fluid and solids and medium at the surface,
• drawing down the level of the fluid within the wellbore annulus;
• flowing the natural gas from the natural gas deposit into the wellbore annulus once the fluid level reaches a predetermined level;
• producing the natural gas in the wellbore annulus to a surface collection facility.
