The Evaluation of a New Environmentally Friendly Combined Product for Application in the North Sea for Effective Scale and Corrosion Control

Abstract The introduction of more stringent environmental regulation within the North Sea has resulted in increased focus on developing environmentally acceptable inhibitors for application to oil and gas applications. One approach in fulfilling these criteria has been the emergence of multifunctional combined products. This paper demonstrates how this approach can be used effectively to control both scale and corrosion problems. A new environmentally friendly product was developed within the laboratory that gave improved scale control performance against conventional products while also affording excellent corrosion control. A series of tests were conducted to establish the performance of the product as well as compatibility with produced fluids from a North Sea platform. The results of the laboratory investigation are discussed in detail including the advantages and disadvantages offered by this approach as well as the potential environmental benefits.
