摘要： The use of degradable components has become a more common practice in subterranean operations for such applications as temporarily isolating zones or diverting flow. A major concern of operators in using degradable tools is the ability to ensure that the tool has completely degraded and is no longer blocking or obstructing flow. This issue can be resolved through the use of degradable components that include one or more chemical additives that are released upon the partial or full dissolution of the degradable component, and which can be used to facilitate in the dissolution of the degradable component. The degradable component can optionally include tracer elements that are released upon the partial or full dissolution of the degradable component, and which can be detected at the surface to ensure the desired degradation or removal of the degradable component as well as hydraulic access to that stage.

摘要： A degradable elastomeric material that is formed from a composite blend of elastomeric particles in a continuous degradable binder. The degradable binder is generally a water-soluble binder which has a temperature dependent solubility in water and brine systems. Such degradable elastomers are particularly useful in the fabrication of degradable oil tools, among other applications.

摘要： 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.
