DESCRIPTION:Co-author: Rouhi Farajzadeh (Shell Global Solution Internation
 al) \n\nThe flow of foam in porous media is a complex process depending on
  the media properties (permeability\, porosity and surface chemistry)\, oi
 l saturation\, gas and liquid fraction. Foam appears to be very viscous in
  a porous media which increases the sweep efficiency. This displacement pr
 operty is used for oil recovery processes. Several works have studied the 
 effect of oil on foam. Depending on the oil and the surfactant chemistry\,
  oil destabilizes foam. The oil effect has been linked to various mechanis
 ms like disjoining pressure\, liquid fraction\, entering and spreading coe
 fficient\, emulsification\, etc. However the oil effect in porous media is
  still not well quantifiable. In addition\, coarsening\, coalescence and d
 rainage of foam in porous media have been poorly studied. On large scale\,
  relevant for oil recovery applications\, foam flow is simulated by a mobi
 lity reduction model\, which scales down the gas mobility based on empiric
 al parameters. Effect of the physical parameters on the model will be disc
 ussed. We will present numerical and experimental works on the foam floodi
 ng and report the current challenges of the research.\n
