Numerous continuous-length tubular service concept trials and inventions paved the way for the creation of present day CT technology. The following discussion outlines some of the inventions and major milestones that directly contributed to the evolution of the continuous-length tubular products used in modern CT services. The origins of continuous-length, steel-tubing technology can be traced to engineering and fabrication work pioneered by Allied engineering teams during the Second World War. Project 99, code named "PLUTO" (an acronym for Pipe Lines Under The Ocean), was a top-secret Allied invasion enterprise involving the deployment of pipelines from the coast of England to several points along the coast of France.

The well-control stack system is a critical part of the coiled tubing (CT) unit pressure containment package and is composed of a stripper assembly and hydraulically operated rams, which perform the functions described next. For typical well-intervention service, the four ram compartments are equipped (from top down) with: * Blind rams * Tubing shear rams * Slip rams * Pipe rams (Figure 1). Figure 1--Typical quad-ram well-control stack configuration (courtesy of SAS Industries Inc.). The blind rams are used to seal the wellbore off at the surface when well control is lost. Sealing of the blind rams occurs when the elastomer elements in the rams are compressed against each other. For the blind rams to work properly, the tubing or other obstructions across the ram bonnets must be removed.
