Drilling with Composites: An Overview of an Integrated Composite Coiled Tubing Drilling System and Components

Abstract

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.
