Abstract
Official abstract text for this publication.
A system that is usable with a well includes a first tubing string and a plurality of tubing segments. The first tubing string is deployed in the well and includes a plurality of valve assemblies, which span a segment of the first tubing string. The tubing segments are adapted to be deployed in the well inside the first tubing string and attach together in the segment of the first tubing string in a sequence to form a second tubing string in a manner that allows sequential operation of the valve assemblies of the first tubing string.
