Emission management
Emissions management remains an active and crucial research area in the oil and gas industry. It is a broad research category spanning several different directions. The papers of the past year demonstrate the rich diversity of ideas and analytical techniques used for tackling different research questions in this space.
This paper focuses on developing a model that can be used in an automated, end-to-end flare-smoke detection, alert, and distribution-control solution that leverages existing flare closed-circuit television cameras at manufacturing facilities.
This study recommends favoring the combustion of ammonia over hydrogen for the purpose of reducing CO₂ and nitrogen emissions.

Gas flaring, which accounts for 30% of carbon emissions from fossil-fuel operations, dropped globally to a 10-year low in 2021, but questions remain whether 2022 will see a rebound as the industry reboots in a post-COVID-19 world with oil and gas supplies tightening. -
ExxonMobil has initiated front-end engineering design studies to determine the feasibility of developing a South East Australia carbon capture and storage hub in the Bass Strait, where some of Australia’s oldest offshore oil and gas fields are to be decommissioned.

Oil producers encountering pockets of methane typically use flare stacks to burn off the vented gas. However, winds blowing across conventional open flame burners often result in 40% or more of the methane escaping into the air.
-
The agency’s new Global Methane Tracker analysis reports that methane emissions from the energy sector are 70% higher than official figures.
-
It seems obvious that to manage the reduction of methane emissions an operator needs to measure the emissions, report them accurately, and then take action to mitigate them. But what might seem obvious gets tricky: Just what matters, and how can an operator efficiently and accurately measure those factors?
-
The study assessed the CO2 footprint and NO2 emissions for different drill-cuttings treatment alternatives. The values were then used to create an emissions calculator that can be applied to projects to clarify the actual potential for emissions reduction within the drilling-waste-management process.
-
The authors determine that economical and environmentally responsible solutions exist for fluid disposal during well-testing operations.
-
EDF and Carbon Mapper find more than two dozen facilities producing the same near-term climate pollution as about 500,000 passenger vehicles.
-
Moving the needle with the urgency required to deliver on the Global Methane Pledge announced at COP26 requires us to “lean in” to cut methane emissions that are fully within our control across our operations.
-
While uncertainties remain for the coming year, there is also optimism for the upstream industry, a welcome prospect following two sharp downcycles in less than 6 years.
