Abstract
Systems and methods using electrically controlled propellant to operate equipment in subterranean formations are provided. In some embodiments, the methods comprise: providing a tool assembly that comprises a tool body and an electrically controlled propellant; and placing the tool assembly in at least a portion of a subterranean formation. Electrical current may be applied to at least a portion of the electrically controlled propellant to ignite the portion of the propellant to operate a portion of the tool assembly.
Claims20
A method comprising:
- providing a tool assembly that comprises a tool body and an electrically controlled propellant;
- and
- placing the tool assembly in at least a portion of a subterranean formation.
A downhole tool that comprises:
- a tool body;
- an electrically controlled propellant disposed on the tool body;
- and
- an electrically conductive conduit having a first portion in contact with the electrically controlled propellant and a second portion connected to a source of electrical current.
A method comprising:
- providing a packer assembly that comprises:
- a tool body that comprises at least one mechanically actuatable component;
- an electrically controlled propellant disposed on the tool body;
- and
- an electrically conductive conduit having a first portion in contact with the electrically controlled propellant and a second portion connected to a source of electrical current;
- placing the packer assembly in a well bore that penetrates at least a portion of a subterranean formation;
- applying an electrical current to at least a portion of the electrically controlled propellant to ignite the portion of the propellant;
- and
- allowing energy from ignition of the electrically controlled propellant to actuate the mechanical component and set the packer assembly in the well bore.
