      To mount the Christmas Tree

    • B.

      Connect the casing head to the casing spool

    • C.

      Hold casing pipe in place

    Correct Answer
    C. Hold casing pipe in place
    Explanation
    The purpose of a casing hanger is to hold the casing pipe in place. This is an important function as it ensures that the casing pipe remains stable and secure during the drilling and production processes. Without a casing hanger, the casing pipe could move or shift, which could lead to complications such as leaks or instability in the wellbore. Therefore, the casing hanger plays a crucial role in maintaining the integrity and stability of the casing pipe.

    • C.

      Line pipe refers to downhole pipes, while casing and tubing are on the surface

    • D.

      Line pipe is cemented in place, while casing and tubing are not

    Correct Answer
    B. Line pipe refers to pipe on the surface, while casing and tubing are downhole
    Explanation
    Line pipe refers to pipe that is used on the surface, such as for transporting oil or gas from one location to another. On the other hand, casing and tubing are used downhole, meaning they are inserted into a wellbore to provide structural support and to facilitate the extraction of oil or gas from underground reservoirs. Casing is the outermost layer of the well, while tubing is the inner pipe that allows for the flow of fluids. Therefore, the difference between line pipe and casing and tubing lies in their location and purpose.
