Abstract
The present invention provides compositions of oil-soluble inhibitors suitable for use in inhibiting scale formation in a hydrocarbon production system, such as in an oil field. The compositions comprise an acid form of a known scale inhibitor and 2-ethylhexylamine and similar amines. These compositions possess advantages over conventional compositions used for inhibiting scale formation in that they are less toxic, more biodegradable, and less likely to invade the fatty tissues of marine life.
