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.

Environmental risks and opportunities of orphaned oil and gas wells in the United States

Environmental Research Letters, 2023
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

Estimation of Costs and Carbon Offset Credits Associated with Oil Well Plugging Based on Field-verified Natural Gas Emissions from Abandoned Wells of the Kurokawa Oil Field, Japan [PDF]

E3S Web of Conferences
We estimated greenhouse gas (GHG) emissions from abandoned oil wells in the Kurokawa oil field in Akita Prefecture, Japan, to explore the potential costs and carbon offset credits associated with reducing GHG emissions.

Interferences caused by the biogeochemical methane cycle in peats during the assessment of abandoned oil wells [PDF]

Biogeosciences
In the global effort to reduce anthropogenic methane emissions, millions of abandoned oil and gas wells are suspected to be prominent, although thus far often overlooked, methane sources.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...
