A velocity string system includes a lock mandrel. A seal bore assembly attached to the lock mandrel runnable in a production string; and a velocity string sealable in the seal mandrel and separately runnable in the production string. A method for installing a velocity string system in a production string.

System and method to install velocity string

An organization system for a series of objects to be sequentially run downhole is disclosed. The preferred objects are spheres of progressively larger diameter put into a wellbore to land at discrete locations for operation of ports in a given sequence so that a specific producing zone or zones can be completed in increments that preferably go in an uphole direction as progressively larger spheres are inserted. In the preferred embodiment the process is fracturing where a series of ported subs are operated to selectively open for the fracture procedure at a specific location and then close or become isolated when another sphere is dropped. Optionally the balls can be recovered at the surface when production starts. The organizer prevents size confusion and gives a ready feedback as to the progress of a given job. Trays can be stacked and carried in a carrying case.
