Sea water often reacts with the formation water in offshore fields to produce barium, calcium and strontium sulfate deposits that hinder oil production. Newer fields often have more difficult to control scafe problems than older ones, and current technology scafe inhibitors are not able to control the deposits as well as needed. In addition, ever more stringent regulations designed to minimize the impact of inhibhorx on the environment are being enacted. Three new inhibitors are presented that overcome many of the problems of older technology scale inhibitors.
