The disclosure provides a goat head, as a mixing block, for multiple fluids in oilfield applications, the goat head having a reversing directional flow, mixing portion, wear reduction surfaces, and restricted outlet bore. The goat head provides an underneath approach for piping, reducing the overall height, and mixes the fluids dynamically within the goat head from angled flow paths. The goat head then reverses at least a component of the fluid flow direction that enters the wellbore below the goat head and exits the goat head into the well therebelow. The goat head to contains hardened wear surfaces, including surfaces in specific zones, to resist erosion caused by the reversing directional flow. A restricted outlet bore has a cross-sectional area that is less than the sum of cross-sectional areas of the inlets to assist in creating higher velocity and streamlined flow as the fluid exits the goat head.

1. A fracturing system for oilfield applications, comprising: a goat head having a top, bottom, sides, front, and back to form a three-dimensional block, the goat head having a plurality of inlets and at least one outlet, the inlets oriented at an angle between 0 degrees to less than 90 degrees rela
1. A fracturing system for oilfield applications, comprising: a goat head having a top, bottom, sides, front, and back to form a three-dimensional block, the goat head having a plurality of inlets and at least one outlet, the inlets oriented at an angle between 0 degrees to less than 90 degrees relative to the outlet and at least two of the inlets oriented at a nonparallel angle to each other in a horizontal plane, wherein the goat head comprises an opening positioned to receive a flow impact of at least one of the inlets and further comprising a removable cover coupled to the opening to deflect the flow impact. 2. The system of claim 1, wherein the opening is formed on the back of the goat head and the inlets are formed on the front of the goat head. 3. A fracturing system for oilfield applications, comprising: a goat head having a top, bottom, sides, front, and back to form a three-dimensional block, the goat head having a plurality of inlets and at least one outlet, the inlets oriented at an angle between 0 degrees to less than 90 degrees relative to the outlet and at least two of the inlets oriented at a nonparallel angle to each other in a horizontal plane, further comprising a bend formed over a flow surface that changes an angle of fluid flow from the inlets into the outlet. 4. The system of claim 3, wherein at least a portion of the bend comprises a hardened wear surface. 5. The system of claim 3, wherein the outlet comprises a cross-sectional area that is less than a sum of cross-sectional areas of the inlets. 6. The system of claim 3, wherein the outlet comprises a cross-sectional area that is equal to a cross-sectional area of one of the inlets. 7. The system of claim 3, further comprising two or more conduits coupled to the inlets of the goat head and one or more pumps coupled to one or more of the conduits. 8. A method of flowing fracturing fluids through a mixing block, comprising: flowing one or more fluids into at least two inlets of the mixing block at an angle that is between 0 degrees and less than 90 degrees to an outlet of the mixing block;at least partially reversing a flow direction of the fluids between the inlets and the outlet; andflowing the fluid out through the outlet of the mixing block,wherein reversing the flow direction comprises flowing the fluids over a bend formed over a flow surface that changes an angle of fluid flow from the inlets into the outlet. 9. The system of claim 8, further comprising flowing the fluid at the bend over a hardened wear surface.
