Abstract
A method comprises monitoring a resistance over time of a tubing encased conductor (TEC) that electrically connects a first downhole gauge to a second downhole gauge positioned in a borehole deeper than the first downhole gauge. The method includes detecting that a first TEC fault has occurred in the TEC, in response to a change in the resistance being greater than a fault occurrence threshold and in response to an amount of the time of the change being smaller than a fault time threshold.
