Testing of Snorre Field Foam Assisted Water Alternating Gas (FAWAG) Performance in New Foam Screening Model

Improvement of water mist performance with foam additives

Performance of Air Foam Flooding under Low Frequency Vibration

Foam injection is widely applied in amounts of fields to drilling, production, and formation protection. Sometimes, the application result is disappointing, which is caused by the failure of bubble generation in foam flooding. Therefore, it is necessary to seek ways for improving the performance of foam injection. An increased disturbance to the stratum, like the vibration caused by a seismic o...

Formula for a New Foam

As the 2010 phaseout date for chlorofluorocarbons draws nearer, materials engineers are working to find replacements for these ozone-depleting chemicals in the production of plastics and other products. One team of engineers is focusing on a combination of two low-cost and environmentally benign substances--supercritical carbon dioxide and clay nanoparticles--to meet these needs. The result is ...

An Experimental and Theoretical Analysis of Foam Formation in the Sour Gas Sweetening Process

Use of amine solutions for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas is the most common method, and, in this process, operational problems because of foaming are reported. Foaming can lead to the entrainment of liquid into downstream process equipment and might result in a situation in which the process specification...

Behavior of Generated Gas in Lost Foam Casting

In the Lost Foam Casting process, melting point temperature of metal, as well as volume and rate of the foam degradation have significant effect on the mold filling pattern. Therefore, gas generation capacity and gas gap length are two important parameters for modeling of mold filling time of the lost foam casting processes. In this paper, the gas gap length at the liquidfoam interface for a lo...
