A reel assembly having three reels disposed side-by-side on a shaft pays out coiled tubing to an injector. A conveyor is used to support and guide the coiled tubing during travel from the reels to the injector. The conveyor is selectively rotatable such that the conveyor may be directed to the reel which actively pays out the coiled tubing. In another embodiment, two reels are slidably disposed side-by-side on a shaft. A conveyor is used to support and guide the coiled tubing during travel from the reels to the injector. In this embodiment, the conveyor is directed to a specific location on the shaft and the reels are slid into the specific location for coiled tubing payout.
