API RP 19GLHB PDF

This document presents information on the following topics related to gas lift equipment:

the basic principles of gas lift;
gas lift equipment selection;
how various types of gas lift equipment work;
how a gas lift system should be designed.

Information is also included on monitoring, adjusting, regulating, and troubleshooting gas lift equipment. It is intended to familiarize operating personnel with the use of gas lift as an artificial lift system.

The publication of Recommended Practice 19GLHB consolidates content from the following standards:

19G5, Operation, Maintenance, Surveillance, and Troubleshooting of Gas-Lift Installations, 1st Edition
11V6, Recommended Practice for Design of Continuous Flow Gas Lift Installations Using Injection Pressure Operated Valves, 2nd Edition
11V8, Recommended Practice for Gas Lift System Design and Performance Prediction, 1st Edition
19G9, Design, Operation, and Troubleshooting of Dual Gas-Lift Wells, 2nd Edition
19G10, Design and Operation of Intermittent Gas-Lift Systems, 1st Edition
19G11, Dynamic Simulation of Gas-Lift Wells and Systems, 1st Edition

In addition to consolidating content from these other standards, the new standard API 19GLHB presents updated information on gas lift systems, which provide a means of enhancing the natural production of hydrocarbons from a producing oil or gas well. Gas lift is widely used because of its broad spectrum of capabilities to increase production volumes, and the new document provides the reader with a fundamental knowledge of the general aspects of modern gas lift systems.
