Interactive effects of salinity, redox, and colloids on greenhouse gas production and carbon mobility in coastal wetland soils. by Nicholas D Ward, Madison Bowe, Katherine A Muller, Xingyuan Chen, Qian Zhao, Rosalie Chu, Zezhen Cheng, Thomas W Wietsma, Ravi K Kukkadapu

“…Coastal wetlands, including freshwater systems near large lakes, rapidly bury carbon, but less is known about how they transport carbon either to marine and lake environments or to the atmosphere as greenhouse gases (GHGs) such as carbon dioxide and methane. This study examines how GHG production and organic matter (OM) mobility in coastal wetland soils vary with the availability of oxygen and other terminal electron acceptors. …”

A Modern Approach to Analyzing the Flowing Pressures of a Two-Phase CBM and Water Column in Producing Wellbores by Xinfu Liu, Chunhua Liu, Jianjun Wu

“…A modern methodology is presented for the system analysis of flowing pressures in order to forecast the dynamic behavior and solve the forthcoming problems that emerge in two-phase coalbed methane (CBM) wellbores. The proposed methodology involves a numerical integration technique to calculate flowing pressures and pressure drops of CBM and water flow from the bottom hole to the well head. …”
