Foam flooding (or injection of foam) is a common technology to enhance oil recovery. Although the effects of permeability on foam flooding were well studied in many laboratory experiments, little research has been focused on the specificity of low permeability. In this paper, a series of constant-quality nitrogen foam flow experiments were conducted to investigate the effects of permeability on...

This study aimed to reduce the holistic environmental impacts of insulation materials proposed for accommodation a marine cargo ship, and suggest optimal option cleaner ship production, using life cycle assessment. With commercial bulk carrier as case three major insulations were assessed, which wool-based material (mineral wool or glass wool), expanded polystyrene, polyurethane foam. The analy...

Absorption is one of the most established techniques to capture CO2 from natural gas and post-combustion processes. Nevertheless, absorption process frequently suffers various operational issues, including foaming. The main objective current work elucidate effect degradation product on foaming behavior in methyldiethanolamine (MDEA) piperazine (PZ) solution evaluate antifoaming performance poly...

CO2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. In this study, the lower part of Es1 reservoirs in Pucheng oilfield was introduced as the target reservoir. By studying the minimum miscible pressure in CO2 flooding, the reservoir could achieve miscible flooding. Long core displacement experiments prove...

reaction to fire of fire-retarded rigid pur foams and two types of metal faced rigid polyurethane foam core sandwich panel was evaluated by using cone calorimeter test method. the tests were carried out in various radiative heat fluxes from 15 to 75 kw/m2. the radiation rate effect on reaction to fire parameters, including time to ignition (tti), peak of heat release rate (prhr), total heat rel...

Liquid foams have important practical applications in mineral separation and oil recovery. However, the details of the foam mechanics in these applications are poorly understood. Foam scientists have used 2D foam simulations to model foam behavior and 2D visualization solutions have helped them explore and analyze their data. Three-dimensional foam simulations remove some of the simplifying ass...

The relative immobility of foam in porous media suppresses the formation of fingers during oil displacement leading to a more stable displacement which is desired in various processes such as Enhanced Oil Recovery (EOR) or soil remediation practices. Various parameters may influence the efficiency of foam-assisted oil displacement such as properties of oil, the permeability and heterogeneity of...
