Abstract

The invention relates to tubing handling apparatus for injecting tubing into and recovering the tubing from a wellbore. In an embodiment, the apparatus includes a storage reel of coiled tubing, a first injector head and a second injector head for injecting the tubing from the reel into the wellbore. The second injector head may be located between the storage reel and the wellbore, and the first injector head may be disposed between the storage reel and the second injector head. The first and second injector heads can control bending of a length of the coiled tubing from the reel which is passed between the first and second injector heads.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to tubing handling apparatus and associated methods. In addition, the invention relates to a gooseneck device for a tubing injector head.BACKGROUND TO THE INVENTION

[0002] Tubing is commonly used in oil, gas and water wells, to convey fluids between the well and the surface. Coiled tubing is normally supplied in continuous lengths wound onto a reel, and is unwound from the reel as it is injected into the wellbore. Normally the injection of the coiled tubing into the wellbore is controlled by an injector head. In offshore wells, the tubing is injected into the well through a riser, which is secured to the wellhead on the seabed, and which forms a rigid and stationary conduit between the platform or drill ship at the surface, and the wellhead on the seabed. When the platform is subject to heave, the platform and derrick therefore move relative to the injector head attached to the stationary riser. In order to accommodate this rel...
