In an integral production pumping tree, the bottom connection, blow-out preventer, flow tee and top connection are positioned to one side, with the vertical tubing bore off center. Up to three vertical ports are provided in the other side of the tree, for providing access to the production casing bore for an electric heating string, an instrumentation string and a small diameter injection tubing string. The ports accommodate sealed connection assemblies, from which the strings extend. The upper portion of the other side of the tree is cut away to create space for introducing the connecting assemblies. The tubing hanger is provided with matching bores.
