Abstract

A monolithic pumping tree combining a bottom connection, production blow-out preventer section, flow tee section and top connection is cast so as to provide an access port extending downwardly through the side wall of the tree from its outer surface, to connect with either the central vertical bore of the tree or its horizontal bottom surface, thereby enabling coiled tubing to be inserted either into the tubing string bore or into the annulus between the tubing and production casing strings.
