Characterizing methane emissions from orphaned coalbed methane wells in the powder river basin
Environmental Research Communications, 2023 In 2018, the U.S. EPA Greenhouse Gas Inventory (GHGI) began including methane emissions from abandoned oil and gas (AOG) wells and estimated that they may constitute up to 4% of total methane emissions from the oil and gas sector.

Thermal Energy Estimation by In-situ Combustion in An Abandoned Oil Well
Journal of Earth Energy Engineering, 2021 A downside of producing oil is that it can never be fully recovered. After the end of a well's life span, the residual oil remaining in the reservoir on average can be over 30%.

InSAR assets in ground movements survey on abandoned coalfields [PDF]
E3S Web of Conferences, 2022 Rising groundwater in abandoned mines may result in ground movements at the surface overlying underground works. Feedbacks on several abandoned coalfields show that ground uplift is generally observed, reaching in some cases several centimetres or more ...

The effect of the depth and groundwater on the formation of sinkholes or ground subsidence associated with abandoned room and pillar lignite mines under static and dynamic conditions [PDF]
Proceedings of the International Association of Hydrological Sciences, 2015 It is well known that some sinkholes or subsidence take place from time to time in the areas where abandoned room and pillar type mines exist. The author has been involved with the stability of abandoned mines beneath urbanized residential areas in ...
