In this paper the authors present material outlining the stability and performance of an environmentally acceptable product to mitigate scale and corrosion in an oilfield that operates under challenging production conditions. The paper demonstrates that it is possible to develop environmentally acceptable combined scale / corrosion inhibitors that contain mutually compatible components. The products developed showed no decrease in performance with respect to mitigating barite and calcite scale and sweet corrosion after long-term aging at 60°C. This allows products to be used that have an extended shelf life.Oilfields that have limited sub-sea umbillicals necessitate the use of multifunctional products to treat the field’s integrity flow assurance and scale challenges. However it is often the case that the active chemicals in combined products that are used to treat scale and corrosion can interact during long?term storage. This interaction causes the efficacy of the product to decrease over time and results in the product having a reduced shelf life. As a consequence it may be necessary to inject a product above its optimum dose rate or worse a product could be injected that does not perform its intended role. By developing mutually compatible products and optimizing their performance improved efficacy can lead to less overall chemical usage and improved environmental implications.
