Transport of oil droplets through porous media is an important topic in the and gas industry. Oil that are present produced water contribute to injectivity decline during re-injection due retention pores. In literature, phenomenon typically studied by means core/packed bed flooding, which struggles provide a simple inexpensive way visualize events at pore scale. This paper demonstrates microfluidic method for studying transport dilute oil-in-water emulsions media. The allows identification every single event capillary level quantitative analysis spatial distribution retained over volumes injected. Experiments were carried out monodisperse tailored polydisperse emulsions. Moreover, several droplet sizes, flow rates dispersed phase concentrations tested. results showed size has dramatic effect on clogging. Droplets larger than throats underwent complete retention, while smaller little no emulsion experiments. Additionally, experiments with facilitators droplets, latter unlikely experience significant independently former. affected re-entry mechanisms it influenced only number events. It was identified concentration limited At low concentration, obtained statistical sample not sufficiently large unravel trends. developed presents solid foundation further developments studies transport.

Wastewaters generated by crude oil extraction processes, called “produced waters” (PWs), are complex solutions that contain organic compounds, mainly hydrocarbons, and often exhibit high salinity. The large amounts of PWs represent a global issue because their environmental impact. An approach widely used in the industry is reinjection this wastewater into wells after suitable treatment. salt concentration such may be salinity gradient technologies to produce green electricity. Among these technologies, reverse electrodialysis (RED) one most promising. In work, application RED for energy generation from two different real brines was investigated. experimental campaign performed testing 10 × cm2 units long-run continuous operations, monitoring performance more than 25 days. Fouling phenomena, occurring during operation, decrease unit several anti-fouling strategies were adopted tackle issue. As result, positive net power density up 18 days operation obtained. A maximum about 2.5 W/m2 observed, demonstrating how technology could an important strategy harvest industrial waste.
