SYSTEMS AND METHODS TO MONITOR THE CHARACTERISTICS OF STIMULATED SUBTERRANEAN HYDROCARBON RESOURCES UTILIZING ELECTROCHEMICAL REACTIONS WITH METALS
First Claim
1. A method for characterizing a first wellbore extending into a geologic structure comprising a reservoir of subterranean hydrocarbons, the method comprising:
- providing a first fluid composition comprising a base metal into the first wellbore;
wherein corrosion of the base metal in the first wellbore results in electrochemical oxidation of the base metal and electrochemical reduction of a reducible species that generates a gaseous product;
providing at least one sensor in proximity to the first wellbore; and
receiving a signal detected by the sensor at a monitoring unit, wherein the sensor senses a signal resulting from corrosion of the base metal;
wherein the signal is used to determine information relating to characteristics of at least one item selected from the group consisting of;
the first wellbore, extraction of hydrocarbons from the first wellbore, and the electrochemical reduction.

2. A method for characterizing a first wellbore extending into a geologic structure comprising a reservoir of subterranean hydrocarbons, the method comprising:
-
receiving a signal from each of one or more sensors, each signal indicative of a parameter related to electrochemical oxidation of a base metal and electrochemical reduction of a reducible species that generates a gaseous product in the wellbore, at least some of the reducible species introduced into the wellbore in a first fluid composition; and deriving, from at least the signal, information about characteristics of at least one item selected from the group consisting of;
the first wellbore, extraction of hydrocarbons from the first wellbore, and the electrochemical reduction;where each sensor is disposed in a position selected from the group consisting of;
a first wellbore, in a second wellbore close enough to the first wellbore that the sensor can detect its respective parameter, or at the ground surface of the geologic structure. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
