Fiberspar and Conoco jointly developed a 1 1/2 inch O.D. advanced composite coiled tubing prototype for high pressure oil and gas well service. The tubing design is based on a comprehensive set of performance specifications including: axial tensile and compressive behavior; axial and bend cycle fatigue requirements; ultimate burst pressure; combined cyclic bending; and internal pressure. The development philosophy is to utilize standard hardware for steel coiled tubing handling and injector equipment where possible. End couplings designed for easy make-up in the field are developed and advancements are made in stripper technology which are applicable to steel as well as composite coiled tubing.
