Abstract: A drift robot for performing a drifting operation of a wellbore in a subterranean formation is disclosed. The drift robot includes an elongated body to be deployed into a well conduit in the wellbore, a propulsion system for propelling the elongated body to traverse the well conduit, retractable landings attached to the elongated body for selectively anchoring the elongated body to an internal surface of the well conduit, sensors attached to the elongated body to generate sensor measurements of the well conduit, a smart camera disposed at one end of the elongated body to capture camera images of interior features of the well conduit, and a controller configured to navigate the elongated body based at least on the sensor measurements and the camera images.

Abstract: A method for remotely testing wellhead integrity of a well is disclosed. The method includes connecting valves and associated gauges of the well remotely to a supervisory control and data acquisition (SCADA) system, obtaining real time pressure and temperature readings through the SCADA system, detecting, using a thermal infrared camera installed at a wellhead tree and flow lines of the well, potential oil/gas leak, and determining, by the SCADA system and based at least on the real time pressure and temperature readings and a detection result of the thermal infrared camera, integrity of the valves.
