... to exploratory wells. Short-duration tests can have a profound impact in any deepwater field-development setting. Stakes are high when unfavorable productivity and injectivity indices may change the well count calculus. Tools such as formation testers provide a credible alternative, but closed-chamber tests (CCT...

...Standard Vacuuming BHA The sand/well vacuuming system consists of a modified jet pump fitted on the end of CCT, as shown in Figure 2 . The cleanout fluid is circulated down the central string and returned via the coil-coil annulus between the two CT strings. The action of the power fluid...

Composite Coiled Tubing (CCT) offers the potential to exceed the performance limitations of isotropic metals, thereby increasing the service life of the pipe and extending operational parameters. CCT is constructed as a continuous tube fabricated from non-metallic materials to provide high body strength...
