Abstract: A sensor system includes an electrical circuit having plural leads coupled with one or more sensing regions. The sensing regions include gaps having sensing materials that detect an analyte of interest. The gaps close responsive to the sensing material corresponding to the gaps detecting the analyte of interest. One or more processors communicatively coupled with the electrical circuit receive electrical signals from the electrical circuit indicative of the gaps closing responsive to the sensing material of the corresponding gaps detecting the analyte of interest. The electrical circuit is in a closed position in the presence of the analyte of interest. The sensor system is configured to consume an increased amount of power when the electrical circuit is in the closed position relative to the electrical circuit in an open position responsive to the one or more of the gaps closing. A responsive action is determined based on the electrical signals.

Abstract: A system includes a downhole tool having a housing and a passage extending through the housing, where the passage includes an inlet configured to receive a flow of a wellbore fluid and an outlet configured to discharge the flow of the wellbore fluid. The downhole tool includes a heating element configured to heat the flow of the wellbore fluid and to enable the flow of the wellbore fluid to transition to a single-phase fluid flow within the passage. The downhole tool includes a phase composition sensor positioned adjacent the passage and configured to provide feedback indicative of formation of the single-phase fluid flow. The system includes a controller configured to monitor a power consumption of the heating element and to determine an enthalpy of the wellbore fluid based in part on the power consumption and the feedback from the phase composition sensor.

Abstract: A detection system includes a first sensor configured to send a first ultrasonic pulse toward an object in a blowout prevention system. The first ultrasonic pulse has a first parameter. The detection system also includes a second sensor spaced from the first sensor and configured to send a second ultrasonic pulse toward the object. The second ultrasonic pulse has a second parameter that is different from the first parameter of the first ultrasonic pulse. The first parameter and the second parameter are one of an amplitude, a frequency, a duration, an emission time, and an excitation code. The second sensor is further configured to receive the first ultrasonic pulse after the first ultrasonic pulse interacts with the object. The detection system is configured to determine that the first ultrasonic pulse received by the second sensor was sent by the first sensor. The detection system further includes a controller coupled to the second sensor and configured to determine a characteristic of the object based on the first ultrasonic pulse.

Abstract: A sensor system for a sub-sea oil and gas well includes a casing, a transmit coil, a receive coil, and a processor. The casing defines an interior space through which a drilling pipe string transits. The transmit coil is coupled to the casing and is configured to conduct a current pulse and induce an electromagnetic field within the interior space. The electromagnetic field corresponds with the current pulse and interacts with the drilling pipe string. The receive coil is coupled to the casing and is configured to detect the electromagnetic field, including perturbations of the electromagnetic field due to the drilling pipe string's interaction therewith. The processor is coupled to the transmit coil and the receive coil. The processor is configured to compute a diameter of the drilling pipe string based on the current pulse and the electromagnetic field detected by the receive coil.
