Best Practices for Reduction of Methane and Black Carbon from Arctic Oil and Gas Production

The document analyzes the climate impact of Arctic oil and gas production, focusing on short-lived climate forcers (SLCFs) like methane and black carbon. It details emission sources—such as associated gas flaring, venting from storage tanks, and diesel engine exhaust—and proposes mitigation strategies including vapor recovery units, diesel particulate filters, and the use of ultra-low sulfur diesel. The paper emphasizes that while some technologies are standard in lower latitudes, Arctic implementation faces higher costs and infrastructure challenges.

• The Arctic region contains approximately one-fifth of the world's undiscovered, recoverable oil and natural gas, with an estimated 84 percent of these reserves located in offshore areas.
• Black carbon (BC) is particularly damaging in the Arctic because it has a direct warming effect and an indirect effect of reducing the reflectivity of snow and ice, which accelerates melting.
• The disposition of 'associated' natural gas is the largest potential source of both methane and black carbon; when gas cannot be sold or used locally, it is frequently flared, which can lead to incomplete combustion and BC emissions.
• Methane emissions from production are categorized as vented (intentional releases like pneumatic actuator bleeds) or fugitive (unintentional releases like leaking valves).
• High-efficiency mitigation for associated gas includes pipelines, liquefaction (LNG), mini-gas to liquids (mini-GTL) technology, and reinjection into geological formations, the latter of which has been used in Alaska for over 30 years.
• For stationary diesel engines and small ships, the combination of Diesel Particulate Filters (DPF) and Ultra Low-Sulfur Diesel (ULSD) can reduce black carbon emissions by 95-99% by mass.
• Vapor Recovery Units (VRUs) are recommended to reduce methane emissions from storage tanks and FPSOs by an estimated 95%, though installation costs are significantly higher offshore than onshore.
• The document argues that robust monitoring and reporting protocols, backed by legislation, are essential first steps because Arctic emissions are currently not well characterized.
