Claim 25:
26. 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.
