Abstract
A string is equipped with a braking device to regulate its speed into the wellbore through an existing tubular. When the targeted amount of overlap with an existing tubular is accomplished the two tubulars are then joined together. The braking system can take many forms such as externally mounted mechanisms that are speed responsive to vary the braking force. The inside of the tubular can have trapped gas to provide buoyancy and reduce the dropping speed. The braking can be accomplished hydraulically through regulated flow through the tubular or by a combination of a hydraulic and mechanical device. The momentum of the dropped string can also be controlled with a swage device that at the appropriate location lands on a taper and wedges or fuses itself to the surrounding tubular to gain support from the surrounding tubular.
