Abstract
An example logging tool includes an injection system, a detection system, and an electric control and processing system. The injection system includes a gas source, and is configured to inject a first gas from the gas source into a region of a subterranean formation. The detection system includes a gas detection chamber and one or more sensors disposed in the gas detection chamber, and is configured to receive, in the gas detection chamber, a sample from the region of the subterranean formation, and generate, using the one or more sensors, sensor measurements of the sample, The electronic control and processing system includes one or more processors, and is configured to determine one or more characteristics of the subterranean formation based on the sensor measurements.
