 Introduction

Tubing is a relatively small-diameter pipe that is run into a well to serve as a conduit for the passage of oil and gas to the field surface facilities for processing. Tubing must be adequately strong to resist loads and deformations associated with production and work overs. Further, tubing must be sized to support the expected rates of production of oil and gas.
