The role of plastic as a vector for bioaccumulation of hydrophobic organic pollutants has been widely studied. However, the interactions between microplastics (MPs) and crude oil, and the transfer kinetics of sorbed oil from ingested MPs into aquatic…
MgH2 has become a hot spot in the research of hydrogen storage materials, due to its high theoretical hydrogen storage capacity. However, the poor kinetics and thermodynamic properties of hydrogen absorption and desorption seriously hinder the…
Among hydrogen storage materials, Li-Mg-B-H system has attracted a lot of attention due to the simple hydrogen desorption pathway and high theoretical hydrogen storage capacity, but it still faces the disadvantages of high hydrogen desorption…
Characterization of challenging and/or new energy materials (e.g., biomass/biofuels, heavy oils, and solid petroleum products) requires the generation of new and improved analytical technologies. Matrix-assisted laser desorption/ionization (MALDI)…
We developed a novel methodology that combines thermo-analytical measurements and mathematical methods to inform the reliable pyrolytic treatment of specific soil/contaminant systems. Our approach improves upon current "black-box" design methods that…
It is generally accepted that asphaltenes are the main stabilizing agents of water-in-crude-oil emulsions. However, the phenomenon of formation and stabilization of the colloid is complex and requires further studies. In this work, interfacially…
Spontaneous imbibition is the main factor that reduces the fracturing efficiency and damages gas production in shale gas wells, which is regulated by the gaswater interaction. Water (fracturing fluid) is imbibed spontaneously due to the…
The importance of the Carmopolis field in Brazil for the exploration of onshore crude oil dates back to 1963. Currently still in operation, this is a major field, serving as a model for enhanced oil recovery tests. In this field, the differences in…
The gas in-place (GIP) content and the ratio of adsorbed/free gas are two key parameters for the assessment of shale gas resources and have thus received extensive attention. A variety of methods have been proposed to solve these issues, however none…
Methane carbon isotope fractionation (CIF) during shale gas desorption provides a new method to evaluating in-situ gas content and the ratios of adsorbed and free gas as well as predicting the production status of shale gas wells. Considering…
Unconventional natural gas resources including shale and tight gas reservoirs hold most of natural gas reserves around the world. However, these resources pose a great challenge in reserve estimation, modeling flow behavior, reservoir simulation,…
The simulation of the gas flow in tight sandstone reservoir is a very complicated process. Several mechanisms contributed to the natural gas production in tight sandstone reservoirs. One of the main mechanisms is the gas desorption from the rock…
Upper Ordovician Wufeng Formation-Lower Silurian Longmaxi Formation shale in the Sichuan Basin and its periphery is an important horizon for shale gas exploration and development in my country. The rapid on-site desorption instrument independently…
The current state-of-the-art analysis techniques for petroleum fractions has progressed substantially during the past decade. This has helped to further improve the lumping procedures and modeling approaches of these complex systems. Recent advances…
