Patent ID: 11988091

Abstract:
The present disclosure provides a method including: launching a drone-type device into a subsurface terrain, wherein the drone-type device is configured to navigate the subsurface terrain along a path while searching for a source of one or more pollutants; obtaining, using one or more sampling compartments on the drone-type device, at least one sample along the path as the drone-type device travels in the subsurface terrain; measuring, using one or more sensors on the drone-type device on the drone-type device, concentration levels of the one or more pollutants at corresponding locations along the path where the drone-type device obtains the at least one sample; determining a gradient map of the measured concentration levels in the subsurface terrain surrounding the path taken by the drone-type device; and based on, at least in part, the gradient map, determining whether the source of the one or more pollutants has been located.
