Abstract: A sample array includes a substrate, a corrosion proxy coupled to the substrate, and at least one test sample coupled to the substrate. The corrosion proxy is formulated and configured to relate to corrosion of material near the sample array. The at least one test sample is formulated and configured to measure at least one of a physical property and a chemical species. A method of characterizing corrosive conditions includes providing a sample array in a subterranean formation, analyzing the corrosion proxy to estimate corrosion, and analyzing the at least one sample to determine a at least one property selected from the group consisting of a physical property and a concentration of a chemical species. Some methods include correlating a location in a borehole with corrosion and at least one of a physical property and concentration of a chemical species.

Abstract: A sensor system for monitoring downhole corrosion may include a first test sample and a second test sample for measuring corrosion conditions and collecting data related to the corrosion conditions and an electronic circuit. The electronic circuit may include a measuring device for analyzing the first test sample and the second test sample and to obtain corrosion data related to the corrosion conditions and a communication module for transmitting the corrosion data related to the corrosion conditions to a surface above the borehole. A multi-borehole monitoring system may include a plurality of sensor systems disposed in a plurality of boreholes and a monitoring module. The monitoring module may analyze the corrosion data, to manipulate the corrosion data, and to produce a visual representation of the corrosion data. Methods of monitoring corrosion downhole may include receiving the corrosion data at the multi-borehole monitoring system from the plurality of plurality of sensor systems.
