Abstract
An improved coiled tubing reel and unit utilizing a system of two non-continuous spindles, each having a fixed, spaced apart spindle stub, and associated, spaced apart inner hubs secured within the tubing-supporting outer drum of the reel for rotation of the inner hubs about the fixed spindle stubs. The reel assembly permits rotary fluid and wireline connectors and drive motor to be located within the reel's outer drum, for protection from damage and to provide a more compact reel assembly which minimizes the overall width of the unit while maximizing the useable spool length to increase the amount of coiled tubing.
