Large methane release from abandoned hydrocarbon wells in Italy
Abandoned hydrocarbon wells (AHWs) represent an understudied anthropogenic source of atmospheric fossil methane (CH4). To date, CH4 flux measurements from AHWs have been extensively conducted in North America, highlighting the important role of unplugged wells, especially those that can be defined as high-emitters (releasing at least 0.9 t CH4 y−1). In Europe, only a few plugged wells have been measured, in the Netherlands, United Kingdom, and Ge…
Renewable energy production potential of abandoned and orphaned oil and gas wells and sites
Abandoned and orphaned oil and gas well sites may be repurposed for wind and solar energy, while the wells themselves can be redeveloped for geothermal energy production. We estimate the total number of abandoned and orphaned wells in Canada and the United States to be 3,485,480 of which 4% are orphaned and in need of government funding. When normalized by today’s oil production, the United States has twice the number of abandoned and orphaned we…
Environmental risks and opportunities of orphaned oil and gas wells in the United States
Hundreds of thousands of documented and undocumented orphaned oil and gas wells exist in the United States (U.S.). These wells have the potential to contaminate water supplies, degrade ecosystems, and emit methane and other air pollutants. Thus, orphaned wells present risks to climate stability and to environmental and human health, which can be reduced by plugging. To quantify environmental risks and opportunities of well plugging at the nationa…
Saskatchewan’s oil and gas methane
Canada has set ambitious methane emission reduction targets for its oil and gas industry, and recently, the province of Saskatchewan—Canada’s second largest oil producing region—announced it has already exceeded the first of these targets. Using detailed operator-reported emissions data, published for the first time from Saskatchewan in 2022, we estimate the province’s upstream oil and gas methane inventory to independently evaluate the reported …
Oil and natural gas wells across the Nasa ABoVE domain
Arctic-boreal regions are experiencing major anthropogenic disturbances in addition to intensifying natural disturbance regimes as a consequence of climate change. Oil and natural gas (OG) activities are extensive in the Arctic-boreal region of western North America, a large portion of which is underlain by permafrost. The total number and distribution of OG wells and their potential fate remain unclear. Consequently, the collective impacts of OG…
Disturbances in North American boreal forest and Arctic tundra
Ecosystems in the North American Arctic-Boreal Zone (ABZ) experience a diverse set of disturbances associated with wildfire, permafrost dynamics, geomorphic processes, insect outbreaks and pathogens, extreme weather events, and human activity. Climate warming in the ABZ is occurring at over twice the rate of the global average, and as a result the extent, frequency, and severity of these disturbances are increasing rapidly. Disturbances in the AB…
Orphaned oil and gas well stimulus—Maximizing economic and environmental benefits
Orphaned oil and gas wells are abandoned wells for which the cost of environmental impacts usually falls on governments and the general public. Government agencies responsible for well plugging often face funding shortfalls and many orphaned wells remain unplugged. To address this and support the oil and natural gas industry, federal governments are already spending, or considering spending, billions of dollars to plug orphaned oil and gas wells.…
Groundwater phosphorus concentrations
Although observations show that anthropogenic phosphorus (P) can reach groundwater supplies, there has been no comprehensive evaluation of P in groundwater at the global scale and P contamination from sources such as agriculture and oil and gas activities are poorly understood. We compile and analyze 161 321 groundwater P measurements in 12 different countries to determine the extent of P contamination at the global scale. We find that all 12 cou…
Deep groundwater quality in the southwestern United States
Groundwater demands are growing in many arid regions, and the use of non-traditional water resources, especially during extreme droughts, is increasingly common. One non-traditional resource is deep groundwater, which we define from ∼150 m to several kilometers or more deep. We analyze 41 081 data points from 17 basins in the southwestern United States (US) to estimate the distribution of fresh and usable deep groundwater for potential human cons…
