Abstract: A system is provided including a coiled tubing reel apparatus including a reel drum for storing a coiled tubing string spooled on the reel drum and a hydraulic reel drive motor that controls rotation of the reel drum. The system further includes a reel controller that determines an estimated reel back tension for a portion of the coiled tubing string between the reel apparatus and the injector based on a set of parameters related to a coiled tubing operation. The reel controller determines a target reel back tension to be applied to the portion of the coiled tubing string by adjusting the estimated reel back tension based on a historical job dataset. The reel controller then determines and sets a target hydraulic pressure of the reel drive motor to achieve the target reel back tension in the portion of the coiled tubing string.

Abstract: A process for printing porous textile materials, such as pile fabrics, and the resultant products, wherein the poorly defined boundaries between adjacent dissimilarly colored surface areas of the material are subsequently overprinted with a color which is retained adjacent the surface of the textile material to overlie and hide the poorly defined boundary, thus providing a more sharply defined pattern in the textile material.
