1. A system for performing a fracturing operation in a well having a casing head, the system comprising:
a tubing head, connected to the casing head, and comprising a tubing head inner surface machined to mate with a tubing hanger, wherein the tubing hanger is a surface extending portion of a production tubing and the production tubing comprises a conduit for production fluid to flow from a formation to a surface location;
a bushing profile formed by the tubing head inner surface of the tubing head;
a wear bushing having a bushing external surface, wherein the bushing external surface is tapered, and the bushing profile is correspondingly tapered causing the bushing profile and the bushing external surface to mate and allow the wear bushing to sit within the tubing head;
a running tool configured to install the wear bushing into the bushing profile of the tubing head using a cable connected to the running tool that lowers the running tool and wear bushing into the bushing profile of the tubing head;
an orifice formed by the installation of the wear bushing in the bushing profile and the connection between the tubing head and the casing head; and
a frac fluid configured to be pumped into the well to fracture the formation though the orifice created by the wear bushing being installed in the tubing head, wherein the frac fluid is pumped through the wear bushing in a direction from the surface location to the formation.
