AbstractIn 1997, Statoil and Halliburton Energy Services, Inc. began jointly evaluating technologies that could be used to develop a revolutionary coiled-tubing and well-intervention system. This system, which will be deployed initially in the Norwegian sector of the North Sea, sets a new standard for drilling with conventional drilling rigs or coiled-tubing drilling units. The advanced well-construction system consists of a digitally controlled and automated coiled-tubing drilling system that uses a new advanced composite coiled tubing (ACCT) with embedded wires and a tractor-driven bottomhole assembly (BHA). This system enables the geological steering of complex, extended-reach wellpaths that were not previously achievable.This paper discusses a joint development project in which the operator and the service company worked together to design a fit-for-purpose system that met Norways stringent health, safety, and environment (HSE) requirements. The systems three major subsystems are discussed: the digitally controlled and automated surface equipment, the 2 7 /8-in. ACCT with embedded wires, and the drilling and intervention BHA. Test results from qualification and pilot wells are also included.

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

Historically, well drilling operations have been based exclusively on steel pipe. Recently a well construction system that incorporates composite coiled-tubing technology has been introduced. This paper examines this system and its implications for the future, with specific emphasis on composite issues: the pipe and connectors. This revolutionary full-system development encountered numerous challenges, many of which are related to the unique properties of composite pipe in difficult hole conditions. The technological solutions to these challenges are examined in depth.
