Concentric coiled tubing (CCT) is a specialized form of coiled tubing designed for various applications in the oil and gas industry. Unlike traditional coiled tubing, which consists of a single tube, concentric coiled tubing features an inner tube that runs within a larger outer tube. This design allows for the simultaneous flow of fluids through both tubes, making it particularly effective for specific operations such as well cleanouts, drilling, and enhanced oil recovery.
