Abstract
The invention comprises a system for wet screening of oil well proppant at the wellsite to provide a controlled and controllable amount of properly sized and screened proppant and fluid to a frac fluid blending system.
Claims31
A system for creating a slurry, comprising:
- a wet screening assembly comprising a screen with a plurality of openings through which material may pass, and a material hopper with an outlet disposed above at least a portion of the screen;
- a material supply assembly comprising a variable speed motor and a material weight sensor, and wherein the material supply assembly is arranged to supply material to the material hopper at a controlled rate;
- a fluid supply assembly comprising a fluid pump, and wherein the fluid supply assembly is arranged to supply fluid to the wet screening assembly;
- a bin located below the wet screening assembly such that material and fluid that pass through the screen are collected in the bin as the slurry;
- wherein a concentration of material in the slurry is determined by a rate or rates at which the material supply assembly supplies material to the material hopper and/or by a rate or rates at which fluid is supplied to the wet screening assembly;
- and
- a conduit coupled to the bin for passing the slurry from the bin without removing the material from the fluid.

A system for creating a proppant slurry for use in hydraulic fracturing operations, the system comprising:
- a wet screening assembly comprising a screen with a plurality of openings through which proppant and fluid may pass, and a hopper with an outlet disposed above at least a portion of the screen;
- a proppant supply assembly comprising a variable speed motor, and wherein the proppant supply assembly is arranged to supply material comprising proppant to the hopper;
- a fluid supply assembly comprising a pump and a fluid meter, and wherein the fluid supply assembly is arranged to supply fluid comprising water to the wet screening assembly;
- a bin located below the wet screening assembly such that proppant and fluid that pass through the screen are collected in the bin as the proppant slurry;
- an outlet in the bin for passing the proppant slurry from the bin;
- wherein a concentration of proppant in the slurry is determined by a rate or rates at which the proppant supply assembly supplies proppant to the hopper and/or by a rate or rates at which fluid is supplied to the wet screening assembly;
- and
- a conduit coupled to the bin for passing the proppant slurry from the bin without separating the proppant from the fluid.

A system for creating a sand and water slurry for use with a subterranean formation, the system comprising:
- a wet screening assembly comprising a screen with a plurality of openings through which sand and water may pass, a hopper with a sand inlet, a water inlet, and an outlet, the outlet having an area less than a sand inlet area, and the outlet disposed above at least a portion of the screen;
- a sand supply assembly comprising a motor, a variable speed motor drive and a weight sensor, and wherein the sand supply assembly is arranged to supply sand to the hopper;
- a screen leveling assembly wherein the screen can be leveled before or during wet screening of sand;
- a water supply assembly comprising a pump and a flow meter, and wherein the water supply assembly is arranged to supply water to the wet screening assembly;
- a bin located below the wet screening assembly such that sand and water that pass through the screen are collected in the bin as the sand slurry;
- wherein a concentration of sand in the slurry is determined by a rate or rates at which the sand supply assembly supplies sand to the hopper and/or by a rate or rates at which water is supplied to the wet screening assembly;
- and
- a conduit coupled to the outlet for passing the sand slurry from the bin without separating the sand from the water.
