Well Tubing and Packers

Abstract

Most oil wells produce reservoir fluids through tubing strings with packers. This is mainly because tubing strings provide better sealing performance than casing and allow the use of gas expansion to lift oil. Gas wells produce gas through tubing strings to reduce liquid loading problems. Tubing strings are designed by considering tension, collapse, and burst loads under various well operating conditions to prevent loss of tubing string integrity including mechanical failure and deformation due to excessive stresses and buckling. This chapter presents specifications and strengths of various types of tubing specified by American Petroleum Institute that can be used for designing tubing strings in oil and ...
