ABSTRACT:
A tubing hanger and method for reducing loads and stresses on sealing boundaries in a tubing hanger is provided. The tubing hanger has an inner cavity that is sealed with respect to an external well volume present in for example the surrounding tree architecture and wellhead. A control line extends through the inner cavity to communicate with downhole equipment. A pressure compensator is configured to adjust pressure differential between the inner cavity and the external well volume.
