Injection of carbon dioxide (CO2) into coal seam gas reservoirs has been considered one the most popular approaches to enhance methane (CH4) production. However, many geological and engineering factors influence efficiency CH4 displacement by CO2. These include depth-induced changes in pressure temperature, accompanied compounds, moisture content, salinity underground water. Thereby, mechanisms...

Multiple tropospheric gases are analyzed in ten years of observations (2010–2019) using a high-resolution ground-based solar absorption Fourier Transform InfraRed (FTIR) instrument the Colorado Northern Front Range (CNFR). The first year measurements 2010 coincides with start remarkable increase oil and natural (O&NG) extraction region. We show seasonal variations trends atmospheric related to ...

Abstract. Ethane (C2H6) is an important greenhouse gas and plays a significant role in tropospheric chemistry climate change. This study first presents then quantifies the variability, sources, transport of C2H6 over densely populated highly industrialized eastern China using ground-based high-resolution Fourier transform infrared (FTIR) remote sensing along with atmospheric modeling techniques...
