Inhibition additives for hydrochloric acid usage in North Sea oil wells require adherence to regulations calling for continual improvement in environmental characteristics while maintaining performance. Some operating companies have conditions that require the acid system to perform at temperatures above 320°F (160°C). Other companies’ temperature requirements are for much milder conditions. Therefore, a system that meets current environmental standards and the broad range of temperature requirements is desirable. This study details a new inhibitor/intensifier system that meets these broad range requirements for protection of common alloys in low pH fluids.
