Oil & Gas Upstream Subsea Tubing Applications and Capabilities

 

The coiled tubing (CT) industry is a major part of oil & gas upstream subsea applications.  Coiled tubing is used widely in extreme conditions in offshore environments. The North Sea is a  good example of extreme offshore applications. Extreme conditions require a special grade of seamless stainless steel tubing known as 6 Mo (UNS S31254).  Common applications include interventions in wells or for production tubing  to extend the life of “depleted wells”.  Interventions are operations performed in oil wells during production or at the end  of a well’s useful life.  The process of intervention changes the condition of the well or its structure, and can be used for well diagnosis or to assist controlling production.
