Methane emissions from oil and gas (O&G) production and transmission represent a considerable contribution to climate change. These emissions comprise sporadic releases of large amounts of methane during maintenance operations or equipment failures not accounted for in current inventory estimates. We collected and analyzed hundreds of very large releases from atmospheric methane images sampled by the TROPOspheric Monitoring Instrument (TROPOMI) between 2019 and 2020. Ultra-emitters are… 

Global Tracking and Quantification of Oil and Gas Methane Emissions from Recurrent Sentinel-2 Imagery.

Methane (CH4) emission estimates from top-down studies over oil and gas basins have revealed systematic underestimation of CH4 emissions in current national inventories. Sparse but extremely large

Monitoring Methane Emissions from Oil and Gas Operations

The atmospheric concentration of methane has more than doubled since the start of the Industrial Revolution. Methane is the second-most-abundant greenhouse gas created by human activities and a major

Inefficient and unlit natural gas flares both emit large quantities of methane

Flaring is widely used by the fossil fuel industry to dispose of natural gas. Industry and governments generally assume that flares remain lit and destroy methane, the predominant component of

Global tracking and quantification of oil and gas methane leaks from recurrent Sentinel-2 imagery

Methane (CH4) emissions estimates from top-down studies over oil and gas basins have revealed systematic under-estimation of CH4 emissions in current national inventories. Sparse but extremely large

Global mitigation opportunities for the life cycle of natural gas-fired power

Over 100 countries pledged to reduce methane emissions by 30% by 2030 at COP26, but whether gas can serve as a bridge to lower-carbon options remains disputed. With an increasingly global supply

Understanding the potential of Sentinel-2 for monitoring methane point emissions

. The use of satellite instruments to detect and quantify methane emissions from fossil fuel production activities is highly beneficial to support climate change mitigation. Different hyperspectral

Comparing national greenhouse gas budgets reported in UNFCCC inventories against atmospheric inversions

Abstract. In support of the Global Stocktake of the Paris Agreement on Climate change, this study presents a comprehensive framework to process the results of atmospheric inversions in order to make

Methane emissions from China: a high-resolution inversion of TROPOMI satellite observations

Abstract. We quantify methane emissions in China and the contributions from different sectors by inverse analysis of 2019 TROPOMI satellite observations of atmospheric methane. The inversion uses as

Significance Large methane point sources exist across multiple source sectors (e.g., oil, gas, coal, livestock, waste). Lacking is a robust assessment of the relative contribution of strong methane

Locating and Quantifying Methane Emissions by Inverse Analysis of Path-Integrated Concentration Data Using a Markov-Chain Monte Carlo Approach

The action to reduce anthropogenic greenhouse gas emissions is severely constrained by the difficulty of locating sources and quantifying their emission rates. Methane emissions by the energy sector

Quantifying methane emissions from the largest oil-producing basin in the United States from space

A high-resolution satellite data–based atmospheric inversion framework is demonstrated, providing a robust top-down analytical tool for quantifying and evaluating subregional methane emissions from the Permian Basin.

Reconciling divergent estimates of oil and gas methane emissions

This work reconciles top-down and bottom-up methane emissions estimates in one of the country’s major natural gas production basins using easily replicable measurement and data integration techniques and reduces uncertainty in top- down estimates by using repeated mass balance measurements, as well as ethane as a fingerprint for source attribution.

Satellite observations reveal extreme methane leakage from a natural gas well blowout

The detection of large methane emissions from a gas well blowout in Ohio during February to March 2018 is reported using measurements of TROPOMI in its routine global survey, providing quantitative assessment of associated methane emissions.

Remote sensing of methane leakage from natural gas and petroleum systems revisited

Abstract. The switch from the use of coal to natural gas or oil for energy generation potentially reduces greenhouse gas emissions and thus the impact on global warming and climate change because of

Assessment of methane emissions from the U.S. oil and gas supply chain

The magnitude of this leakage was reassessed and it was found that in 2015, supply chain emissions were ∼60% higher than the U.S. Environmental Protection Agency inventory estimate, likely because existing inventory methods miss emissions released during abnormal operating conditions.

Daily Satellite Observations of Methane from Oil and Gas Production Regions in the United States

New measurements from the space-based TROPOspheric Monitoring Instrument (TROPOMI) launched in 2017 are presented that show methane enhancements over production regions in the United States.

Three decades of global methane sources and sinks

Methane is an important greenhouse gas, responsible for about 20% of the warming induced by long-lived greenhouse gases since pre-industrial times. By reacting with hydroxyl radicals, methane reduces

Eight-Year Estimates of Methane Emissions from Oil and Gas Operations in Western Canada Are Nearly Twice Those Reported in Inventories.

Total anthropogenic emission rates of methane from 2010 to 2017 in Alberta and Saskatchewan were derived using hourly atmospheric methane measurements over a six-month winter period from October to March, with a resulting estimate of 3.0 MtCH4 from the oil and gas sector is nearly twice that reported in Canada's National Inventory.

Concurrent variation in oil and gas methane emissions and oil price during the COVID-19 pandemic

Abstract. Methane emissions associated with the production, transport, and use of oil and natural gas increase the climatic impacts of energy use; however, little is known about how emissions vary
