Basic Objectives and Concepts of Matrix Acidizing

This chapter introduces the concept of matrix acidizing, a well-stimulation technique that enhances oil and gas production by dissolving formation damage and improving reservoir permeability. The chapter begins by defining formation damage and its causes, and then reviews various stimulation methods, highlighting the advantages and challenges of matrix acidizing. The chapter then focuses on the objectives, principles, and applications of matrix acidizing, especially for carbonate reservoirs, which are prone to acid dissolution. The chapter also discusses the types of acids used in acidizing and their effects on reservoir properties, as well as the key factors that determine the success of acidizing operations. The chapter aims to provide a comprehensive overview of matrix acidizing and its role in petroleum engineering.
