The casing head is also known as drive pipe—a welded metal flange. It connects the casing to the wellhead assembly, which supports intermediate string and production string and seals space between the casing. Casing Head is also compatible with different type and size of the wellhead assembly.  Therefore, casing head is providing a crossover connection for the installation of the bop, the tubing head, the Christmas tree, and other top wellhead components. It is also used to inject additional cement slurry or balance fluid, monitor the well sink and execute other operating through both of the two bypass holes in the casing head body.
