Corrosion detection for carbon injection wells using a low-cost flat pack

A downhole corrosion detection system, comprising:

• a plurality of corrosion test wires configured to extend along a downhole tubular at least between a first axial position and a second axial position disposed downhole with respect to the first axial position, wherein each corrosion test wire of the plurality of corrosion test wires is configured to transmit a corresponding electrical signal applied at the first axial position, and wherein a first corrosion test wire of the plurality of corrosion test wires includes a unique cross-sectional shape with respect to a second corrosion test wire of the plurality of corrosion test wires;
• an electrical insulator disposed between the plurality of corrosion test wires and the downhole tubular to prevent electrical shorting between the plurality of corrosion test wires and the downhole tubular, wherein the electrical insulator includes a wire housing having individual recesses corresponding to each corrosion test wire of the plurality of corrosion test wires, wherein the individual recesses are configured to prevent electrical shorting between the plurality of corrosion test wires;
• and
• a measuring device configured to measure the ability of each corrosion test wire of the plurality of corrosion test wires to transmit the corresponding electrical signal to determine an amount of corrosion of each corrosion test wire of the plurality of corrosion test wires.
