Foam mobility in heterogeneous porous media

WebFor the last decades, the foam was used for improved oil recovery (IOR) and enhanced oil recovery (EOR) technologies, such as acid treatment [1,2], gas mobility control [], foam-assisted water altering gas injection [], gas shut-off [], etc.In all EOR technologies, foam should create stable multiphase media with high apparent viscosity for gas conformance … WebSummary In heterogeneous formations foam is expected to reduce mobility more in high permeability layers hence to divert flow towards low permeability regions. This has been shown experimentally by several authors by comparing core-scale foam displacements on core plugs of contrasted average permeability and by using a two-dimensional laboratory …
