Abstract
An assembly for use on a wellhead includes a tree body including an internal main bore arranged in use to be aligned with the bore of a wellhead housing; the tree body including a lateral bore extending through the tree body from the internal bore; the tree body further including means for connecting to a connector so as to align the internal bore of the tree body with an internal bore in the connector, in use the tree body and the connector together forming a horizontal tree. The tree body may include one or more integrally formed bores and valves to provide fluid flowpaths for the annulus and/or cross-over functions. A wellhead assembly including the tree assembly is also provided.
