Christmas tree is a key equipment to control the pressure in wellhead and adjust the flow rate of oil/gas production operation.It is used on both surface and subsea well to control and regulate oil production management and other operations.A Christmas tree is the cross-over between the wellhead casing and the flowline to the production process.It controls and regulates the wellhead pressure and the flow of hydrocarbon fluids and enables the well to be shut off in an emergency. It also provides access into the well for wirelining, coiled tubing and logging operations.The tree is designed to withstand all pressure levels such as gas lifting, gas injection, and the pressures arising due to a fracture or kill operation. Wellhead acidification fracturing,paraffin removal could also be finished when needed.
