Abstract
Thermally induced graphene sensing circuitry and methods for producing circuits from such thermally induced circuits are disclosed along with applications to hydrocarbon exploration and production, and related subterranean activities. The thermally induced graphene circuitry advantageously brings electrically interconnections otherwise absent on oilfield service tools, enabling components and tools to become smart.
Claims18
A thermally induced graphene sensing circuitry, comprising:
- a surface of a component;
- a first polymeric material that includes carbon coating at least a portion of the surface of the component;
- a pattern comprising graphene that forms a printed circuit comprising a zig-zag shape on the surface of the component;
- a coating comprising an electrically-insulating second polymeric material on at least a second portion of the surface of the component;
- the coating of the second polymeric material comprising openings providing access to the pattern;
- and
- the pattern comprising electrical connections, wherein the electrical connections include at least endpoints to the printed circuit.
