  • Patent number: 4887673
    Abstract: A bowl-slip assembly is used to complete shallow wells having a tension set hold down device such as a packer or tubing anchor. The bowl includes a trap door which is opened to allow the bowl to pass around the tubing string and rest on an underlying well head support, such as a tubing head. The trap door is closed and a short set of slips placed to receive the load of the tubing string and transfer it to the tubing head at a time when it is necessary to attach a Christmas tree to the tubing string and tubing head. The trap door bowl and slips are easily installed and removed and require a minimum clearance between the top of the tubing head flange and the bottom flange of the Christmas tree.
