Abstract
A method of treating a subterranean formation penetrated by a wellbore, according to which a tool is fabricated of a material that breaks up or dissolves in the presence of a fluid and is inserted in the wellbore for performing a function in the wellbore. The fluid is then introduced to the tool to break up or dissolve portions of the tool and the remaining portions of the tool fall to the bottom of the well.
Claims17
A method of treating a subterranean formation penetrated by a wellbore, comprising the steps of:
- providing a casing in the wellbore;
- providing a tool comprising a material that breaks up or dissolves in the presence of an acid;
- inserting the tool in the casing for performing a function;
- perforating the casing to permit the flow of fluids from the formation, through the perforations, into the wellbore, through the tool, and to the ground surface;
- and
- introducing the acid to the tool to break up or dissolve the tool.
A method of treating a subterranean formation penetrated by a wellbore, comprising the steps of:
- providing a tool comprising a material that breaks up or dissolves in the presence of an acid;
- inserting the tool at a predetermined location in the wellbore to seal the interface between the tool and the wellbore;
- introducing a fracturing/stimulation fluid into the wellbore for passing into the formation for promoting the flow of production fluids from the formation;
- and
- introducing the acid to the tool to break up or dissolve the tool.
