摘要:
A method of deploying a tool into a pressurized well is provided that includes providing the well with a wellhead having a blow out preventer coupled thereto; setting a pressure barrier within the well at a distance below the blow out preventer that is at least as long as the length of the tool to create a pressure chamber between the blow out preventer and the pressure barrier; and opening the blow out preventer to allow for conveyance of the tool into the pressure chamber.
