Abstract
A system includes a subsea well and a carousel of tools. The carousel of tools is adapted to automatically and selectively deploy the tools in the well to perform an intervention in the well. The flow of fluid in a well is halted, and a tool is deployed from within the well while the fluid is halted. The tool is allowed to free fall while the fluid is halted. The flow is resumed to retrieve the tool.
