Corrosion continues to be a threat to the petroleum industry. It risks people’s lives, the environment, and assets integrity, in addition to the financial losses. In fact, the annual global cost of corrosion was estimated in 2013 to be around US$2.5 trillion (3.2% of 2013 global GDP). Of this amount, approximately 15-35% (i.e. US$375 to US$875 billion annually) can be avoided through proper corrosion control management and advanced mitigation technologies

Corrosion continues to be a threat to the petroleum industry. It risks people’s lives, assets integrity and the environment. These risks are mitigated by different means such as selection of appropriate materials, chemical treatment, cathodic protection, protective coatings, and process control. One of the most common corrosion control measures is the use of corrosion inhibitors. This is a cost-effective option that can be applied to upstream, mid-stream and downstream facilities. This has driven the research institutes and the chemical manufacturers to invest on developing corrosion inhibitor chemistries for field-specific applications. In spite of all the efforts being put, there are still many important aspects about corrosion inhibition treatment that need to be researched for a better understanding of the chemicals’ performance, monitoring, laboratory testing, and field application. This paper highlights knowledge gaps to invite focused research to help bridging the gaps between operators, research institutes and developing companies. These gaps are classified in four main areas: Field Monitoring, Facility Design, Laboratory Testing, and Simulation & Prediction.

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.

Carbon steel (CS) material is widely used for the equipment in oil and gas production industry due to its mechanical properties associated with a relatively low cost, compared to other materials. Depending on the corrosiveness of the fluid that is vehiculated, the use of carbon steel is generally associated with the injection of a corrosion inhibitor (CI) in order to mitigate internal corrosion. Corrosion inhibitors are generally used in continuous injection at an injection rate that is depending on the corrosiveness of the fluid. Based on the operational feedback, the internal standards are recommending for multiphase pipelines CI injection rates in the range of 50 - 70 ppm for temperature below 80°C of and of 150 to 200ppm for temperatures above 100°C. These injection dosages are typical values that are considered in the laboratory tests for the qualification of the CI and they are adjusted on-site based on the monitoring results.

Corrosion inhibitors provide a critical barrier to internal corrosion, presenting the most cost-effective form of mitigation and enabling operators to use carbon steel where it would otherwise be impractical. The correct selection and validation of inhibitors is essential to ensure successful field deployment, providing safe and reliable operation. However, the selection and optimization of a corrosion inhibitor for a particular field application is not trivial.
