Abstract: An apparatus and method for using a pressure-powered tool to perform a downhole operation in a well determine the operating condition of the tool based on indications of pressure in a region associated with the tool. If the pressure indications are indicative of an undesired operating condition, corrective action is taken, such as mechanically shifting the tool or rupturing the rupture disc of an electric rupture disc (ERD) system to shift the tool to a desired operating condition.

Abstract: The disclosure relates to an emission detector for monitoring methane emissions at one or more industrial facilities. The emission detector includes: an enclosure that supports a plurality of sensors, wherein the enclosure is configured to permit atmospheric gas to flow by diffusion into space at or near the plurality of sensors, wherein the plurality of sensors include at least one atmospheric sensor configured to measure atmospheric properties of the atmospheric gas that flows into the space at or near the plurality of sensors as well as at least one gas sensor configured to measure concentration of methane in the atmospheric gas that flows into the space at or near the plurality of sensors.

Abstract: A system for detecting methane includes a body and a shaft extending from the body. The system also includes a wind sensor coupled to the shaft. The wind sensor is configured to measure a wind direction and a wind intensity. The system also includes a pyranometer coupled to the body. The pyranometer is configured to measure ambient light. The system also includes a methane sensor positioned on or in the body. The methane sensor is configured to measure a methane concentration in ambient air.
