Patent number: 11927581Abstract: 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).Type: GrantFiled: September 3, 2021Date of Patent: March 12, 2024Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Raphael Gadot, Adam Huynh, Andrew J. Speck, Andrew Emil Pomerantz, Gocha Chochua

Publication number: 20230326201Abstract: Methods and apparatus for fugitive emission detection. In some embodiments, the method can include planning and performing aerial inspections of a plurality of structures within one or more facilities by determining a flight path for a scanning of fugitive emissions from a plurality of structures within one or more facilities. The flight path can cover a set of structure clusters that can be serviced by a base. The method can also include using a computer-implemented clustering method to identify the set of structure clusters that can be serviced by the respective base. The clustering method can be a hierarchical multilevel clustering method. The method can also include scanning the plurality of structures for fugitive emissions using an airborne sensor. The airborne sensor can be mounted to a flight vehicle launched from the base. The method can also include classifying the plurality of structures based on results of the scanning.Type: ApplicationFiled: April 7, 2022Publication date: October 12, 2023Inventors: Kashif Rashid, Andrew J. Speck, Andrew Emil Pomerantz

Publication number: 20220364947Abstract: A leak detection system includes a light source configured to output emitted light into a region of water, and a light detector configured to receive returned light from the region of the water and to output a detector signal indicative of the returned light. The leak detection system also includes at least one controller configured to detect hydrocarbons within the region of the water in response to detecting a hydrocarbon wavelength within the returned light, to determine at least one position of the hydrocarbons within the region of the water based on a time difference between a first time at which the emitted light is output from the light source and a second time at which the returned light at the hydrocarbon wavelength is received at the light detector, and to generate a three-dimensional model of a subsea structure based on the detector signal.Type: ApplicationFiled: October 7, 2020Publication date: November 17, 2022Inventor: Andrew J.

Publication number: 20210255157Abstract: A method is provided for mitigating fugitive methane emission, which includes scanning a plurality of facilities for fugitive methane emission using an airborne sensor, and classifying the plurality of facilities based on results of the scanning. Optionally, further inspection of at least one facility of the plurality of facilities can be performed to detect and locate fugitive methane emission based on the classifying. Optionally, at least one facility can be selectively repaired based on the further inspection in order to mitigate fugitive methane emission. In another aspect, a planning workflow is provided that employs a clustering method to define cluster data representing a set of facility clusters in a geographical region that are associated with a particular base.Type: ApplicationFiled: July 19, 2019Publication date: August 19, 2021Inventors: Kashif RASHID, Andrew J.

Patent number: 9618446Abstract: A wellbore tool for determining a speed of sound of a fluid sample, such as a hydrocarbon sample or a wellbore fluid, is described herein. The wellbore tool includes a photoacoustic system for analyzing the fluid sample. The photoacoustic system includes a laser system that generates a laser pulse, an interface disposed between the fluid sample and the laser system, and an acoustic detector that receives an acoustic pulse that is generated in response to absorption of the laser pulse. The acoustic pulse is generated when the laser pulse is absorbed by the fluid sample or the interface. This acoustic pulse then moves through the fluid sample and is detected by the acoustic detector. The acoustic pulse is then used to determine a speed of sound of the fluid sample.Type: GrantFiled: January 28, 2014Date of Patent: April 11, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Andrew J.
