Scale and Paraffin Causes and Methods of Control

This paper deals with a dual subject concerning scale and paraffin problems encountered in the production of petroleum. Scale formation is caused by an upset in equilibrium conditions within a given system and this is explained in detail. Several methods of control are discussed and optimum conditions of control outlined. Chemical treatment for scale control is discussed at length since this is the most practical method of control in the production of oil. Paraffin or wax formation in oil production equipment is explained as to types and different areas of these occurring types. Chemical treatment for removal and prevention is discussed at length.
