Apparatus and method of delivering a fluid using direct proppant injection

An apparatus and method for delivering a fluid mixture using direct injection to a mixing apparatus. The apparatus 100 including a proppant storage vessel 102 configured to contain therein a proppant material and output a proppant output flow at ambient pressure to a solid feed pump assembly 104. The apparatus further including a fracturing fluid storage vessel 128 configured to contain therein a fracturing fluid and output a fracturing fluid output flow at a fracture fluid blending pressure. The solid feed pump assembly 104 configured to output to a mixing apparatus 124, a proppant output flow at the fracture fluid blending pressure. The mixing apparatus 124 configured to output a fluid mixture of the proppant and the fracturing fluid at the fracture fluid blending pressure. The mixing apparatus 124 coupled to a high pressure pump assembly 142 and configured to deliver the fluid mixture therein to a downstream component at an injection pressure.
