Miscible viscous fingering occurs when a less fluid displaces more one in porous media or Hele–Shaw cell. Such flow instabilities are of particular interest variety applications flows and displacements subsurface energy environment systems. In this study, we investigate the miscible dynamics experimentally using water to displace glycerol sealed cell with two wells located it instead at boundar...

A switchable-hydrophilicity solvent (SHS) is a solvent that in one state forms a biphasic mixture with water but can be reversibly switched to another state that is miscible with water. We describe a mathematical model of the behaviour of CO2-triggered SHS that narrows the search field for these solvents in terms of their basicity and hydrophilicity. By its predictive power, the mathematical mo...

For low permeability sandstone reservoirs, CO2 flooding has been proved to be an effective method enhance oil recovery. Reservoir A is a typical conglomerate reservoir in Xinjiang oilfield. The strong water sensitivity, and the injection pressure continues rise. Furthermore well drop. According screening conditions of flooding, can easily achieve miscible with moderate temperature. A...

Flooding and submergence impose widespread and unpredictable environmental stresses on plants and depress the yield of most food crops. The problem is increasing, as is the need for greater food production from an expanding human population. The incompatibility of these opposing trends creates an urgent need to improve crop resilience to flooding in its multifarious forms. This Special Issue br...

The Oil & Gas Journal, in 2004, states that CO2 flooding is the fastest-growing enhanced oil recovery technique in USA, and production derived from CO2 projects has more than tripled from 50,000-Barrels/day to 200,000-Barrels/day. Cyclic injection of CO2 and N2 combines environmental benefits attendant to reducing CO2 concentrations in the atmosphere and economic benefits realized through impro...

Flooding regimes of different depths and durations impose selection pressures for various traits in terrestrial wetland plants. Suites of adaptive traits for different flooding stresses, such as soil waterlogging (short or long duration) and full submergence (short or long duration – shallow or deep), are reviewed. Synergies occur amongst traits for improved internal aeration, and those for ano...
