Maximizing hole conservation while optimizing well economics in both conventional and deepwater wells is a continual challenge. Solid expandable tubular systems address this challenge and others by applying technology that provides significant solutions. Solid expandable tubular systems have been installed in both openhole and cased-hole wellbores since November 1999. These installations occurred in a variety of well environments on land, offshore, and in deepwater to solve a myriad of drilling and completion challenges. This paper will discuss case histories in depth by describing drilling challenges surrounding the use of solid expandable tubular technology and the conditions leading to the use of this technology.
