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.

Abstract: A load cell apparatus especially suitable for detecting and indicating loads on tubing injected into or withdrawn out of a well with an injector apparatus. The load cell apparatus is located longitudinally directly below the injector apparatus to avoid angling of the tubing as it is run into, or pulled out of, a well. Two gauges are provided to independently indicate positive and negative loads on the tubing and to facilitate determining whether the pipe has hit an obstruction in a well. A fluid chamber is provided to support the weight of the tubing head, facilitating accurate load cell readings.
