Wellbore filtration system and method for using inverse pyramid compartments and suction pumps

A system for eliminating impurities from a slurry taken from a hydrocarbon wellbore, comprising:

• an inlet configured to receive the slurry;
• a plurality of cleaning compartments in fluid communication with said inlet that are coupled together in downstream succession, each cleaning compartment having an inverted pyramidal configuration with a plurality of V-shaped walls defining an interior area and that terminate at an outlet and that is operable for downward settling of the solids from the slurry,
• each cleaning compartment including an upward directional Weir plate having (1) a lower section that is closed so as to block a remainder portion of the slurry that was not extracted from the slurry from flowing into the interior area of a next downstream cleaning compartment and having (2) an upper section that is open so as to allow the remainder portion of the slurry to flow into the interior area of the next downstream cleaning compartment, and
• each cleaning compartment including a downward directional Weir plate each having (1) an upper section that is closed so as to block a remainder portion of the slurry that was not extracted from the slurry from flowing into the interior area of a next downstream cleaning compartment and having (2) a lower section that is open so as to allow the remainder portion of the slurry to flow downstream toward a respective outlet of a respective cleaning compartment.

A system for separating solids from semi-liquid water stream recovered from a hydrocarbon well, comprising:

• an inlet configured to receive a slurry;
• a plurality of cleaning compartments in fluid communication with said inlet that are coupled together in downstream succession, each cleaning compartment having an inverted pyramidal configuration with a plurality of V-shaped walls defining an interior area and that terminate at an outlet and that is operable for downward settling of the solids from the slurry;
• a desander device displaced from and in fluid communication with said plurality of cleaning compartments via a desander conduit, said desander device having a desander pump that is operable to suction the slurry downwardly toward said outlet of a respective cleaning compartment when energized so as to extract a portion of the slurry;
• a desilter device displaced from but in fluid communication with said next downstream cleaning compartment via a desilter conduit, said desilter device having a desilter pump that is operable to suction a respective slurry portion downwardly toward an outlet of said next downstream cleaning compartment when energized so as to extract a portion of the respective slurry portion;
• wherein each cleaning compartment includes an upward directional Weir plate having (1) a lower section that is closed so as to block a remainder portion of the slurry that was not extracted from the slurry from flowing into the interior area of a next downstream cleaning compartment and having (2) an upper section that is open so as to allow the remainder portion of the slurry to flow into the interior area of the next downstream cleaning compartment, and
• wherein each cleaning includes including a downward directional Weir plate each having (1) an upper section that is closed so as to block a remainder portion of the slurry that was not extracted from the slurry from flowing into the interior area of a next downstream cleaning compartment and having (2) a lower section that is open so as to allow the remainder portion of the slurry to flow downstream toward a respective outlet of a respective cleaning compartment.
