Drilling Riser

Drilling risers, deployed for drilling oil wells in deep offshore, are classified as low pressure and high pressure based on the operational conditions. Production risers are developed for

Drilling riser

A drilling riser is a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility. Drilling risers are categorised into two types: marine drilling risers used with subsea blowout preventer (BOP) and generally used by floating drilling vessels; and tie-back drilling risers used with a surface BOP and generally deployed from fixed platforms or very stable floating platfor
