Installing the Tubing Tubing is run into the well (smaller diameter compared to production casing and removable) to serve as a way for oil or gas to flow to the surface. Packer is attached to it just near the bottom. Packer is placed at a depth just above the producing interval. When the packer is expanded, it grips the wall of the production casing and forms a seal between outside of tubing and inside of casing

Installing the Christmas Tree A collection of valves called a Christmas tree is installed on the surface at the top of the casing hanger. As the well’s production flows up the tubing, it enters the christmas tree. So, the production can be controlled by opening or closing valves on the christmas tree.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
