Fugitive emissions of methane from abandoned, decommissioned oil and gas wells.
This study considered the fugitive emissions of methane (CH4) from former oil and gas exploration and production wells drilled to exploit conventional hydrocarbon reservoirs onshore in the UK. This study selected from the 66% of all onshore wells in the UK which appeared to be properly decommissioned (abandoned) that came from 4 different basins and were between 8 and 79 years old. The soil gas...
متن کاملDirect measurements of methane emissions from abandoned oil and gas wells in Pennsylvania.
Abandoned oil and gas wells provide a potential pathway for subsurface migration and emissions of methane and other fluids to the atmosphere. Little is known about methane fluxes from the millions of abandoned wells that exist in the United States. Here, we report direct measurements of methane fluxes from abandoned oil and gas wells in Pennsylvania, using static flux chambers. A total of 42 an...
متن کاملIdentification and characterization of high methane-emitting abandoned oil and gas wells.
Recent measurements of methane emissions from abandoned oil/gas wells show that these wells can be a substantial source of methane to the atmosphere, particularly from a small proportion of high-emitting wells. However, identifying high emitters remains a challenge. We couple 163 well measurements of methane flow rates; ethane, propane, and n-butane concentrations; isotopes of methane; and nobl...
متن کاملGeothermal energy from abandoned oil and gas wells using water in combination with a closed wellbore
Binary cycle power plants have been used successfully for electricity generation utilizing co-produced fluids from active onshore oil wells. Adapting this process for use on abandoned wells by circulating the binary working fluid down the wellbore has been previously proposed and a selection of fluids evaluated. This work proposes and evaluates an approach using water as the wellbore fluid in c...
متن کاملThe Costs of Reducing Greenhouse-Gas Emissions
Human activities around the world are producing increasingly large quantities of greenhouse gases, particularly carbon dioxide (CO2) resulting from the consumption of fossil fuels and deforestation. Most experts expect that the accumulation of such gases in the atmosphere will result in a variety of environmental changes over time, including a gradual warming of the global climate, extensive ch...
