[1] Although shelf seas account for only 7% of the oceanic surface area, recent observations demonstrate that they host significant ocean-atmosphere CO2 fluxes. A mechanism implicated in driving a significant CO2 sink in the temperate shelf seas is the Continental Shelf Pump. Here we present an analysis of the impact of sea-level rise, and the consequent flooding of continental shelves, on the ...

Dimethyl ether (DME) is a compound first introduced by Shell as chemical solvent for enhanced oil recovery (EOR). This study aims to investigate the efficiency of EOR using minimum miscible pressure (MMP) and viscous gravity number when mixed CO2 DME injected. Adding water-alternating-gas process reduces MMP number. Reduction in results conditions at lower pressures, which has favorable effect ...

Wettability is one of the main parameters controlling CO2 injectivity and movement plume during geological sequestration. Despite significant research efforts, there still a high uncertainty associated with wettability CO2/brine/rock systems how they evolve exposure. This study, therefore, aims to measure contact angle sandstone samples varying clay content before after laboratory core flooding...
