ABSTRACT:
A composite of a well treatment agent adsorbed onto a water-insoluble adsorbent is useful in the treatment of oil and gas wells and may be introduced, as a well treatment fluid, with a carrier fluid. The water-insoluble adsorbent may be activated carbon, silica particulate, precipitated silica, zeolite, diatomaceous earth, ground walnut shells, fuller's earth and organic synthetic high molecular weight water-insoluble adsorbents. Suitable as the well treatment agent are scale inhibitors, corrosion inhibitors, paraffin inhibitors, salt inhibitors, gas hydrate inhibitors, asphaltene inhibitors, oxygen scavengers, biocides, foaming agent, emulsion breakers and surfactants.
