Abstract
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.
