TABLE OF CONTENTS Liquid loading of a gas well is the inability of the produced gas to remove the produced liquids from the wellbore. Under this condition, produced liquids will accumulate in the wellbore leading to reduced production and shortening of the time until when the well will no longer produce.
This book deals with the recognition and operation of gas wells experiencing liquid loading. It presents materials on methods and tools to enable you to diagnose liquid loading problems and indicates how to operate your well more efficiently by reducing the detrimental effects of liquid loading on gas production.
This book will serve as a primer to introduce most of the possible and most frequently used methods that can help produce gas wells when liquids begin to become a problem. Liquid loading can be a problem in both high rate and low rate wells, depending on the tubular sizes, the surface pressure, and the amount of liquids being produced with the gas. In this book you will learn:
How to recognize liquid loading when it occurs
How to model gas well liquid loading
How to design your well to minimize liquid loading effects
What tools are available to assist you in the design and analysis of gas wells for liquid loading problems
The best methods of minimizing the effects of liquids in lower velocity gas wells and the advantages and disadvantages of these methods
How and why to apply various artificial lift methods for liquid removal
What should be considered...
