  7. Abstract:
  8. The primary purpose of acidizing operations in the oil and gas industry is to enhance hydrocarbon production. Acidizing has been a common and conventional method for years, especially when production engineers face issues like declining reservoir pressure leading to reduced production rates. Initially, the treatment solution is referred to as matrix acidizing. In acidizing operations, different additives are combined with the acid to control its behavior in the reservoir. These additives may include iron control agents, corrosion inhibitors, friction reducers, and more. Incompatibility among these additives, the acid, and reservoir fluids can lead to severe damage to the reservoir. Therefore, compatibility of acid additives with crude oil is crucial, and adhering to industry standards and conducting laboratory, field, and application tests are of paramount importance. In this project, laboratory experiments will be conducted on the properties of a foam-forming additive known as "foaming agent." Foaming agents are used in various oilfield operations, including drilling as drilling mud foam and in acidizing as acid diverters. To perform these experiments, a device capable of generating and maintaining foam under high-temperature and high-pressure conditions (reservoir conditions) is required. The experiments will investigate the foaming agent's properties, such as foam stability at different temperatures and pressures, considering variations in surfactant type, surfactant concentration, and water salinity, in the presence and absence of oil. Chapter 1 provides a detailed explanation of acidizing and acidizing additives, while Chapter 2 focuses on foaming agents, including their structure and a review of previous research. Chapter 3 discusses the design and construction of the experimental apparatus, and Chapter 4 and Chapter 5 present the experimental results and recommendations for using this foaming agent
