The hydrocarbon resources of shale gas and tight oil have made a significant impact on
North American energy reserves over the past decade. The production of so-called …

Around 50% of humankind relies on groundwater as a source of drinking water. Here we
investigate the age, geochemistry, and microbiology of 138 groundwater samples from 95 …

Releases of stray natural gas into groundwater from oil and gas exploration, production, or
storage can pose a risk to groundwater users and landowners in the form of a fire or …

Oil and gas well leakage is of public concern primarily due to the perceived risks of aquifer
contamination and greenhouse gas (GHG) emissions. This study examined well leakage …

The potential contamination of shallow groundwater with inorganic constituents is a major
environmental concern associated with shale gas extraction through hydraulic fracturing …

Methane leakage caused by well integrity failure was assessed at 28 abandoned gas wells
and 1 oil well in the Netherlands, which have been plugged, cut and buried to below the …

Subsurface natural gas release from leaking oil and gas wells is a major environmental
concern. Gas migration can cause aquifer contamination, explosive conditions in soil gas …

Concern persists over the potential for unconventional oil and gas development to
contaminate groundwater with methane and other chemicals. These concerns motivated our …

High-volume, hydraulic fracturing (HVHF) is widely applied for natural gas and oil production
from shales, coals, or tight sandstone formations in the United States, Canada, and …

In the pursuit of global net zero carbon emissions and climate change mitigation, ongoing
research into sustainable energy sources and emission control is paramount. This review …
