The expense attributable to scaling in oil producing operations totals many millions of dollars annually. Causes of precipitation and deposition are fairly well understood but better methods of control are needed. In order to evaluate chemical scale inhibitor components, a laboratory testing device was designed. Performance of sequestrants, surface active agents, colloids, and mixed compounds in the laboratory tester are discussed. Polyphosphates and sodium carboxymethyl cellulose proved effective for calcium carbonate scale and calcium sulfate scale, respectively. Results of tests made over a period of several years led to the development of an inhibitor composition that is capable of inhibiting both carbonate and sulfate scales. The inhibitor is now in field use. 5.8.2, 3.2.3, 8.4.3
