Abstract: A method and system are disclosed for moving equipment into and through a conduit that is preferably an oil and/or gas production well, wherein use is made of an uphole equipment storage and handling unit via which equipment modules can be moved into a launch conduit and connected to a shuttle device which is able to locomote itself as a wireless tractor via the launch conduit into and from the underlying conduit.

Abstract: A method and system for measuring data in a fluid transportation conduit, such as a well for the production of oil and/or gas. The system employs one or more miniature sensing devices which comprise sensing equipment that is contained in a preferably spherical nut-shell which has an outer width which is smaller than the internal width of the conduit. One or more sensing devices are released sequentially in the conduit and are induced to move in longitudinal direction through the conduit to measure data at desired intervals of time, without requiring a complex infrastructure.
