ABSTRACT:
Solid, slowly dispersible well treatment composites are provided which have a sufficiently high melting point to prevent melting of the composite in hot weather. The composites have a low solubility and high specific gravity compared to prior art treatment agents; thus the composites readily sink in well fluids and slowly release treatment ingredients over time, depending on the downhole conditions. The composites include a nonylphenol ethoxylate having at least about 50 moles of ethylene oxide per mole of nonylphenol and a fatty acid amide having from 16-20 carbon atoms. Preferably, the composites further include a weighting agent and active ingredients selected from the group consisting of corrosion inhibitors, scale inhibitors, bactericides, scale converters, foaming agents, and mixtures thereof.
