Such remedial work can be performed using workover rigs – also known as pulling units, completion rigs or "service rigs" – to pull and replace tubing, or by the use of well intervention techniques utilizing coiled tubing. Depending on the type of lift system and wellhead a rod rig or flushby can be used to change a pump without pulling the ...

Drilling in deep waters can be performed by two main types of mobile deepwater drilling rigs: semi-submersible drilling rigs and drillships.Drilling can also be performed from a fixed-position installation such as a fixed platform, or a floating platform, such as a spar platform, a tension-leg platform, or a semi-submersible production platform.
This component sits in the upper portion of the wellhead, within the tubing head flange and serves as the main support for the production tubing. The tubing hanger may be manufactured with rubber or polymer sealing rings to isolate the tubing from the annulus. The tubing hanger is secured within the tubing head flange with lag bolts.
