Abandoned oil and gas wells, if improperly plugged, provide a potential pathway for gas and fluid migration to the surface. Recently published studies have concluded that a limited number of abandoned wells in Pennsylvania, Wyoming, Colorado, Utah, and Ohio emitted methane at rates that were ...
More than 27,000 abandoned oil and gas wells lurk in the hard rock beneath the Gulf of Mexico, an environmental minefield that has been ignored for decades. No one - not industry, not government - is checking to see if they are leaking, an Associated Press investigation shows. The oldest ...
More than 1 million abandoned wells are scattered across the U.S., left behind when oil and gas companies cease operations. The wells are insidiously becoming an environmental threat as they leak methane, a major contributor to climate change. Jeff Berar
Texas, New Mexico and North Dakota. As there have been only limited studies on wells in the state, it is currently unclear if Colorado abandoned oil and gas wells emit methane and, if they do, how similar the emission profile is to other states in the US. To address this, the ECMC ...
Abandoned oil and gas wells (AOGW) with high bottom-hole temperature contain abundant geothermal energy, which can be retrofitted to a novel geothermal system for different utilizations without high-cost drilling. Thus, at recently, some researchers concentrate on evaluation of the performance of ...
New research released by Columbia University's Center on Global Energy Policy and Resources for the Future examines the environmental and job creation benefits of plugging orphaned and abandoned oil and gas wells.
Tapping into abandoned oil and gas wells in Pennsylvania, products of the state's long history of energy extraction—could provide a future source of affordable geothermal energy, according to Penn State scientists. "This research shows that with creativity we can convert what could be an environme...
be an effective means to store excess heat energy from industrial sources and eventually more sustainable sources like wind and solar," Baser said. "The underground reservoir essentially acts as a large underground battery while repurposing abandoned oil and gas wells. It is a win-win situation."...
While we are appreciating the harm coming from methane emissions, it is of concern that the US and Canada are underestimating the methane coming from abandoned oil and gas wells. Nichola Groom discusses in an article on the Reuters website. U.S. and C
A detailed study was made of the potential for abandoned oil and gas wells in the Lower Tuscaloosa sand of Mississippi and Louisiana to act as conduits for movement of saline water from the Lower Tuscaloosa into underground sources of drinking water (USDW's). Finite-difference numerical modeling...
