Abstract
A coil tubing injector assembly includes a frame structure and a pair of gripper chain drive systems mounted to the frame structure. The pair of gripper chain drive systems are disposed in a common plane and spaced apart from each other, and adapted to engage a first and a second coil tubing string to inject both of the first and second coil tubing strings into, and withdraw both the first and second strings from, a subterranean well. The first and second coil tubing strings may be injected synchronously or asynchronously depending on the structure of the injector. The coil tubing injector assembly reduces the time required to perform many downhole operations, and therefore reduces well completion, stimulation and re-completion expenses.
