  • Patent number: 11918962
    Abstract: A method of determining a dry proppant concentration in a fracturing fluid includes combining a wet proppant with a carrier fluid in a mixer to form the fracturing fluid. The dry proppant concentration of the fracturing fluid leaving the mixer is determined using a moisture content of the wet proppant entering the mixer, wherein use of the moisture content prevents overestimation of the dry proppant concentration. The method can be preformed using a system for injecting fracturing fluid into a borehole, the fracturing fluid including a carrier fluid mixed with a wet proppant including a dry proppant dampened with a dampening liquid.
