Applications Update - Advanced Composite Coiled Tubing

Abstract

Composite Spoolable Pipe for use in the Oil and Gas Industry is a new emerging technology. Enabling benefits include increased corrosion resistance, major weight reduction over steel as well as increased fatigue resistance. One company is close to commercial introduction of composite spoolable pipe for both well servicing and well completion operations. This paper will detail the latest application developments achieved at the time of the conference. It will cover the advancements made since the last update, SPE paper No. 38414 "Update on Composite Spoolable Pipe Developments" presented at the 2nd North America Coiled Tubing roundtable in April 1997. The focus will be on the application of this technology in its first commercial operations. P. 215

Non-metallic pipe systems for use in oil and gas

“…Thermosetting flexible tube, [21][22][23][24][25] as typified by the Fiberspar products shown in Fig. 9, was first developed in response to the need for a non-metallic replacement for steel coil tubing.…”

The current and future trends of composite materials: an experimental study

“…14 The most important advantages of composite over the conventional steel are light weight, corrosion and fatigue resistance, high stiffness and strength, and design flexibility. 18 Composite material properties can be converted into important financial and performance benefits during offshore operations. Studies have shown that the use of composite products can reduce offshore capital requirements, decrease maintenance costs, and enable operations that otherwise are not feasible both technically and financially.…”

“…The earlier mentioned definition or characteristics of composites that make them ideal candidates for oilfield application include resistance to chemical and cathodic corrosion, high strength, light weight, and flexibility. 18 Generally speaking, composites have a higher strength-to-weight ratio than steel. With the ability to control the type, amount, and direction of application of the reinforcement material, composite materials become an ideal candidate for widely varying pressure applications.…”
