In addition to being the principle greenhouse gas, carbon dioxide (CO2) is also the principle source of carbon for photosynthesis. Although the stimulation of plant growth by rising CO2 is usually viewed as a positive aspect of climate change, the rise in CO2 is indiscriminate with respect to the stimulation of both anthropogenically important and deleterious plant species. Here we present labo...

CO2 flooding, a promising technique of enhanced oil recovery, is widely used for its capability boosting and reducing greenhouse gas emissions. In this study, the displacement performance supercritical tested in laboratory under immiscible flooding. The results show that: Supercritical improves by virtue low viscosity, high diffusivity, easy dissolution. With same pore volume (PV), flooding sig...

Surfactant alternating gas/CO 2 (SAG) flooding is a promising enhanced oil recovery (EOR) technology, which has the potential to improve production beyond primary and secondary water methods. However, performance of SAG restricted due instability under high salinity reservoir conditions excessive surfactant adsorption. One convenient relatively low-cost option overcome limitations use low (LSW)...
