  • Patent number: 10662765
    Abstract: Methods and apparatus for monitoring and controlling wellsite emissions. A mobile emissions monitoring device is operated in airspace above a wellsite to generate and transmit a monitor signal related to emissions in the airspace. The emissions may be associated with wellsite equipment at the wellsite. A processing system in receipt of the monitor signal operates to cause a change in an operational parameter of the wellsite equipment based on information conveyed by the monitor signal.
    Type: Grant

  • Patent number: 9624799
    Abstract: A unitary, skid-type sound attenuator assembly for simultaneously managing sound from multiple sources. The assembly may include a dedicated muffler for each sound source. In turn, each of these mufflers includes an outlet for directing sound toward a location such as between the various mufflers of the assembly so as to provide an added level of noise cancellation. Additionally, the assembly may include an attenuator at such a common central location for further noise reduction. The attenuator may also serve a filtering function, for example where the sound sources are engines and the assembly is utilized for managing exhaust therefrom such as in an oilfield environment.
