Abstract: A wellbore tool includes a wellhead to be installed at an entrance to a wellbore formed through a subterranean zone. The wellhead includes an uphole wellhead end that can extend upward from the entrance, and a downhole wellhead end that can extend downhole into the wellhead. The wellhead defines an opening extending from the uphole wellhead end to the downhole wellhead end. A spacer tool is attached to the downhole wellhead end, and includes an uphole spacer tool end and a downhole spacer tool end. The spacer tool defines a tapered opening tapering from end to end. The tool includes a master valve attached to the downhole spacer tool end of the spacer tool. The master valve defines a flow pathway fluidically coupled to the opening defined by the wellhead and the tapered opening defined by the spacer tool.
