Approaches to characterizing methane emission at an industrial facility using an unmanned air vehicle (UAV) equipped with navigational instruments and methane gas sensors. A scan area associated with the industrial facility is defined. The scan area can be logically partitioned into a plurality of pixels based on information provided by an intelligent agent. A flight plan for a flight of the UAV can be created to cover the pixels of the scan area. The UAV can execute the flight plan and collect time-series navigational data and time-series sensor data as the UAV executes the flight plan. The flight path of the UAV can be dynamically adjusted during the flight by an agent to ensure that the flight path of the UAV covers the scan area. A two-dimensional (2D) image of methane concentration over the scan area can be constructed from the time-series navigational data and the time-series sensor data.

Methods and systems for characterizing methane emission employing mobile methane emission detection

Methane monitoring system

Systems and methods presented herein generally relate to greenhouse gas emission management and, more particularly, to greenhouse gas emission management systems and methods for performing greenhouse gas detection sensor placement planning, leakage source tracing, and quantification of leakage source detections for oil and gas production facilities.

Method and apparatus for methane leakage detection

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.

Integrated methane monitoring system

Systems and methods presented herein generally relate to greenhouse gas emission monitoring and, more particularly, to a greenhouse gas emission monitoring workflow using various different types of sensors. For example, a system includes a plurality of sensors located within an oil and gas worksite. At least one sensor of the plurality of sensors is configured to detect a status of equipment at the oil and gas worksite. The system also includes a greenhouse gas emission analysis system configured to receive sensor data from the plurality of sensors. The greenhouse gas emission analysis system is also configured to correlate the sensor data from the plurality of sensors (e.g., using one or more reduced order models (ROMs) that reduce the computational complexity of computational fluid dynamics model simulations of previously collected data relating to operation of the oil and gas worksite). The greenhouse gas emission analysis system is further configured to determine an existence of a greenhouse gas emission within the oil and gas worksite, a location of the greenhouse gas emission within the oil and gas worksite, and a quantity of the greenhouse gas emission within the oil and gas worksite based at least in part on the correlation.

Greenhouse gas emission monitoring systems and methods

A system for measuring and control of shock and vibration is disclosed. The system may include a bottomhole assembly having a downhole end and an uphole end opposite the downhole end. A drill bit may be located at the downhole end of the bottomhole assembly and a powered rotary steering system may be located in the bottomhole assembly. The system may also include a first drilling mechanics module located in the bottomhole assembly, proximate the powered rotary steering system and the drill bit. The first drilling mechanics module may be coupled in electronic communication to the power rotary steering system. The system may also include a plurality of drilling dynamics measurement units distributed along a length of the bottomhole assembly, between the downhole end and the uphole end. The plurality of drilling dynamics measurement units may be coupled in electronic communication with the first drilling mechanics module.

Measurement and control of shock and vibration

The present disclosure relates to a power isolation adapter which can enable the use of multiple power sources in a bottom hole assembly (BHA) by isolating the power sources on a tool bus while maintaining a communication bus across the BHA. Such power sources may be part of a measurement-while-drilling (MWD) module, such as a mud turbine generator, providing power as a DC signal. The power isolation adapter isolates the power sources by blocking DC signals, but maintains an AC communication bus across the BHA. The ability to use multiple power sources in a BHA thus allows for more complex BHA configurations that normally could not be powered using a single power source.

A wireline configurable toolstring is conveyed within a wellbore extending into a subterranean formation via a tubular string to which the wireline configurable tool string is coupled in a manner permitting relative motion of the wireline configurable toolstring and the tubular string. The wireline configurable toolstring converts rotary motion imparted by rotation of the tubular string, or by fluid flow resulting from reciprocation of the tubular string, into electrical energy. The wireline configurable toolstring also comprises at least one wireline configurable instrument powered by the electrical energy.

Power and/or communications are transmitted through the annular coil to an inductively coupled second, mandrel coil that is attached to the rotor. By leveraging resonantly tuned circuits and impedance matching techniques for the coils, power and/or data can be transmitted efficiently from one coil to the other despite relative movement and misalignment of the two coils.
