The prevention of internal corrosion remains a significant challenge during the production of oil and gas. The use of film forming corrosion inhibitors is an important and cost-effective means of protecting assets from corrosion. These chemicals operate by forming a protective layer between the corrosive species present in the produced fluids and the pipe surface.

Corrosion inhibitors provide a cost effective method for internal corrosion control of carbon and low alloy steel infrastructure within the oil and gas industry. The correct selection and validation of inhibitors is essential to ensure successful, safe and reliable operation of infrastructure. Corrosion inhibitors used in upstream oil and gas production are characteristic of surfactant molecules, which adsorb at the metalsolution interface, creating a dynamic physical barrier that reduces electrochemical dissolution.

Corrosion of pipelines made of carbon steel and exposed to wet hydrocarbons containing CO₂ and H₂S is a common but serious problem encountered in petroleum industry and its occurrence causes enormousexpense due to production downtime, accidental injuries, and replacement costs. Control and prevent corrosion using chemical treatment (e.g. corrosion inhibitor injection) is one of the most cost-effective solutions and commonly practiced methods to prevent corrosion failures in pipelines in oil and gas industry. Generally speaking, the active corrosion inhibitor (CI) components in commercial CI packages are usually organic, nitrogen-based surfactants such as amines, imidazoline and its derivatives. Due to the amphiphilic nature of surfactants, a good fraction of the injected CI will inevitably go into the oil phase through partitioning and to the oil/water interface.

The application of corrosion inhibitors are fundamental to the safe and reliable operation of carbon steel infrastructure, presenting one of the most cost effective methods of internal pipeline corrosion control when deployed correctly. Despite decades of application in the oil and gas industry, a number of gaps remain in relation to our fundamental understanding of the performance of inhibitors. This is particularly true in the context of partitioning, and more so when the system under consideration comprises multiple surfactants. Part 1 of this two-part paper provides a detailed insight into the fundamentals of surfactant partitioning. Initially, the role of micellization in influencing single surfactant partitioning/distribution behavior between oil and brine is discussed, providing theoretical explanations for single surfactant system responses. The complexity of the systems examined increases with consideration extending to multi-surfactant environments, accompanied by discussion of idealized theoretical behavior. Subsequently, an idealized model to predict multi-component distribution responses between oil and brine is presented. To explore the model’s capabilities, experimental partitioning and micellization data collected from previous studies for two benzyl ammonium chloride corrosion inhibitors (BAC-C12 and BAC-C16) is integrated into the model. Such integration permits investigation into the effect of surfactant concentrations, relative surfactant molar ratios and water cut on partitioning/distribution behavior.

In Part 1 of this two-part paper, a predictive model for multi-component partitioning was developed based on knowledge of individual component micellization and partitioning characteristics. In Part 2, the model’s validity is assessed through comparison with experimental partitioning data for an 1 wt.% NaCl brine:toluene system containing mixtures of two benzylammonium chloride corrosion inhibitors (BAC-C12 and BAC-C16). Following model validation, the implications of the experimental partitioning behavior on corrosion inhibition performance are examined via rotating cylinder electrode (RCE) experiments. Through selected experiments, the important role of each of the two surfactants and their relative molar concentration in influencing overall corrosion inhibition performance is examined. While BAC-C12 exhibited poor inhibition in isolation, when combined with BAC-C16 at specific molar ratios, BAC-C12 played a crucial role in retaining the longer chain surfactant in the aqueous phase. This response enabled BAC-C16 (the more effective surfactant corrosion inhibitor) to work synergistically with BAC-C12 to suppress carbon steel corrosion more effectively than the two components alone under these particular conditions.
