The T3 TimeSaver™ Wellhead system is a two piece wellhead with one through bore and one restricted bore. It utilizes a fluted mandrel hanger as the primary option for hanging casing. It allows a standard slip hanger to be used in the situation where pipe is stuck. There are multiple configurations for the Timesaver wellhead, depending on the drilling application required.
