Abstract

This paper provides a comprehensive overview of acid fracturing, a critical technique employed in the petroleum and natural gas industry to enhance productivity. We delve into the underlying principles, mechanisms, and applications of acid fracturing, highlighting its role in mitigating formation damage and improving reservoir permeability. The study explores various acid fracturing techniques, including matrix acidizing, fracture acidizing, and stimulated reservoir volume (SRV) creation. We discuss the selection of appropriate acid types, concentrations, and injection rates based on reservoir characteristics and wellbore conditions. Furthermore, we examine the challenges and limitations associated with acid fracturing, such as acid spending, formation damage, and environmental concerns. To address these issues, we propose potential solutions and future research directions. This paper offers valuable insights for industry professionals seeking to optimize their acid fracturing operations and improve performance.
