Abstract:
An engineered composite system designed to be passive or inert under one set of conditions, but becomes active when exposed to a second set of conditions. This system can include a dissolving or disintegrating core, and a surface coating that has higher strength or which only dissolves under certain temperature and pH conditions, or in selected fluids. These reactive materials are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties, but which can be stored and used for long periods of time without degradation.

Claim (Index 32):
A method of dissolving, degrading, reacting or combinations thereof a core in the presence of a fluid environment comprising:\n a) providing a core having a surface layer about said core, said core dissolvable, degradable, reactive, or combinations thereof in the present of said fluid environment, said surface layer not or essentially not dissolvable, degradable, or combinations thereof in the presence of said fluid environment until exposed to an activation event; b) exposing said surface layer to said activation event to cause said surface layer to dissolve, degrade, or combinations thereof to ultimately cause said core to be exposed to said fluid environment, said exposure of said core to said fluid environment causing said core to dissolve, degrade, react, or combinations thereof, said activation event includes one or more events selected from the group consisting of a temperature change of said fluid environment, a pH change of said fluid environment, exposure of said surface layer with an activation compound, a change in composition of fluid environment, exposure of said surface layer to an electrical charge, exposure to of said surface layer to certain electromagnetic waves, a change in salt content of said fluid environment, a change in electrolyte content of said fluid environment, exposure of said surface layer to certain sound waves, exposure of said surface layer to certain vibrations, exposure of said surface layer to certain magnetic waves, and exposure of said surface layer to a certain pressure.
