ABSTRACT:
The amount of crystallized salt in an oil and/or gas well may be minimized or reduced by use of a fructan, such as inulin, or a derivative as a salt block inhibitor. A preferred salt inhibitor is the salt of carboxyalkyl inulin such as a sodium salt of carboxymethyl inulin. The salt block inhibitor may be adsorbed onto a water-insoluble adsorbent.
