We strongly recommend that a scale inhibitor formulation be tested in the water you will be treating to determine whether it will cause insoluble precipitates, prior to issuing a recommendation. Generally, the product to recommend should be completely soluble in the
produced water so that you may derive the highest benefit from its application. This should hold true especially for surface applications where it is necessary to continuously inject the product into a flow-line. Otherwise, it is possible to plug a flow-line with calcium salts of the
scale inhibitor. One possible exception may be a scale inhibitor squeeze, where it may be desirable to have the inhibitor precipitate in the formation to extend the life of the squeeze.
