Abstract: This invention relates to two apparatus and one method for use in spooling composite coiled tubing onto a coiled tubing reel. One apparatus includes the modification of tubing reel cores currently in common use by the direct adhesion of a compliant material to the hub. Another apparatus modifies the commonly used tubing reel hub by affixing several panels concentric to the hub and mounted on compression springs. The method entails the pressurization of the composite coiled tubing prior to spooling onto the tubing reel, and subsequently releasing the pressure within the composite tubing after it has been spooled onto the tubing reel. Both apparatus and the method protect the reel core by absorbing or eliminating the radially inward forces of the composite tubing resulting from the pressurization and corresponding contraction in length of the spooled composite coiled tubing.

Abstract: An end connector for fuse with composite coiled tubing for use in downhole wellbore operations is disclosed. The connector comprises intermediate portions of first and second end portions connected thereto. The first end portion has threads defined thereon to mate with threads defined on the inner surface of the composite coiled tubing. The outer surface of the end connector is flush with the outer surface of a composite coiled tubing when connected thereto. The connector has a means for providing a seal between the end connector and the composite coiled tubing and is adapted to be connected to apparatus, tools and equipment used in downhole wellbore operations in which coiled tubing is utilized.
