DOWNHOLE APPARATUS AND METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240011367 titled 'DOWNHOLE APPARATUS AND METHOD

Simplified Explanation

The abstract describes a downhole tool that includes a heater and a container enclosing a volume of compacted thermite. A volume of flowable alloy is provided above the heater, and a fusible bulkhead may be placed between the heater and the alloy to allow direct conduction of heat. The housing containing the alloy can be separated from the heater by heating a fusible socket that anchors a tensioned support member. The thermite can have an internal volume to receive the alloy, and the heater can be activated to melt the alloy, which then solidifies to form a bore-sealing plug.

  • The downhole tool includes a heater and a container enclosing compacted thermite.
  • A volume of flowable alloy is provided above the heater.
  • A fusible bulkhead allows direct conduction of heat from the heater to the alloy.
  • The housing containing the alloy can be separated from the heater by heating a fusible socket.
  • The thermite has an internal volume to receive the alloy.
  • The heater can be activated to melt the alloy, which solidifies to form a bore-sealing plug.

Potential Applications:

  • Borehole sealing in oil and gas wells.
  • Wellbore isolation in geothermal drilling.
  • Underground mining operations.
  • Sealing of underground storage facilities.

Problems Solved:

  • Provides a reliable and efficient method for sealing boreholes.
  • Allows for controlled and precise sealing of wellbores.
  • Reduces the risk of fluid or gas leakage from boreholes.
  • Enhances the safety and integrity of underground operations.

Benefits:

  • Improved wellbore integrity and sealing.
  • Increased efficiency and reliability in borehole sealing.
  • Cost-effective solution for wellbore isolation.
  • Enhanced safety and environmental protection in underground operations.


Original Abstract Submitted

a downhole tool comprises a heater including a container enclosing a volume of compacted thermite. a volume of flowable alloy is provided above the heater. a fusible bulkhead may be provided between the heater and the alloy and provides for direct conduction of heat from the heater to the alloy. a housing containing the alloy may be separated from the heater by heating a fusible socket that anchors an end of a tensioned support member. the thermite may define an internal volume adapted to receive alloy. the heater may be activated to melt the alloy and the alloy may then solidify to form a bore-sealing plug.
