Abstract: In the present application, a method for installing a component into an oil field tree is described. The method includes installing a sealing device into a component to block a primary flow path through the component; coupling the component with the sealing device installed to an oil field tree in fluid communication with a wellbore; adjusting at least one valve in the oil field tree to provide an alternative flow path that bypasses the sealing device; and performing well operations, such as installation operations, via the alternative path. Further, in other embodiments, the oil field tree may be a production tree utilized to produce hydrocarbons from the wellbore or an injection tree utilized to injection fluids into the wellbore.
