Abstract
A wet frac-sand well site delivery system is a process and method of storing, measuring and regulating the percent solids or PPA (pounds of proppant added) in a sand slurry. The wet sand delivery system is a closed loop, on-site storage system that can receive and store wet frac-sand. The wet sand delivery system takes the wet sand directly from the wash plant and transports it to a wet sand storage pit. From the wet sand storage pit, the sand is pumped directly to a blender or regulator for mixing into a sand slurry for subsequent delivery to a frac pump.
Claims13
A wet-frac sand delivery system comprising:
- a tank for storing wet sand;
- a sand slurry regulator comprising:
- a supply line for receiving wet sand from the pit,
- a return line to return wet sand to the pit,
- a flow meter,
- a density meter, and
- a delivery line for delivering wet sand slurry;
- a source pump which pumps wet sand from the pit to the sand slurry regulator through the supply line;
- a blender for mixing the wet sand slurry;
- and
- wherein the sand slurry regulator monitors at least one of the flow and density of the wet sand slurry and adjusts at least one of the flow and density to deliver wet sand slurry through the delivery line to the blender with a desired concentration of solids,
- wherein the wet sand slurry is fed from the blender to one or more frac pumps.
