Apparatus for deploying coiled tubing into a wellbore include a neck portion extending between end connections, where the end connections are configured to be attached to a coiled tubing tool string, and a main flow passage, at least one secondary flow passage and at least one electrical device passageway extending through the neck portion and the end connections. In some aspects, a wireline cable or an optical fiber is disposed in the electrical device passageway, and a well treatment fluid flows through the main flow passage. The main flow passage may have a substantially circular cross sectional shape. In some aspects, the apparatus includes at least one secondary flow passage having a substantially circular cross sectional shape, which may be a tube disposed within the main flow passage. The electrical device passageway may in some cases be a tube disposed within the main flow passage. |
