Abstract
A split tubing hanger for a well has two semi-cylindrical tubing hanger bodies. A seal has a ring portion which seals the tubing hanger bodies to the bore of a tubing head. The seal also has a diametrical band portion which joins the ring portion. The band portion seals between the two tubing hanger bodies. The bodies are run separately and land on a landing shoulder in the bore of the tubing head. The landing shoulder has upward extending tabs which engage recesses in the load shoulders of the tubing hanger bodies. The landing shoulder is a landing ring which is split and locates within a groove formed in the bore of the tubing head. An anti-rotation device prevents the landing ring from rotating relative to the tubing head.
