Flare Gas Measurement Innovation: Retain Flow Metering Accuracy Even if Gas Composition Changes


Dec 12, 2016
Matthew Olin, President & CEO
Written By:
Matthew Olin, President & CEO

It’s a fact oil wells almost always produce natural gas along with the petroleum. Nine times out of ten, the excess gas (typically hydrocarbons) is flared off or simply vented as-is during upset conditions in the process. The environmental impacts of “flaring” this excess gas into our atmosphere has resulted in government regulations like 40 CFR […]
