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 …
Foam Flow in Heterogeneous Porous Media: Effect of Crossflow
WebMay 11, 2024 · Abstract. In this work, fundamental understanding of phase displacements involved in polymer-enhanced air foam is investigated which was not well discussed in the available literature. To do this, a series of foam injection experiments were performed on heterogeneous rock-look-alike micromodels in the presence and absence of a single … Webshows a significantly improved sweep in the heterogeneous porous media compared with 100% gas injection.28 Various foam models have been proposed to simulate foam flow through porous media, among which the most promising ones are the mechanistic methods based on bubble population Received: May 10, 2012 Revised: April 16, 2013 Published: … how to stop notifications on garmin watch
Parametric studies on foam displacement behavior in a layered ...
WebMay 1, 2024 · Foam injection is well accepted as an enhanced oil recovery (EOR) method. In this study, we carried out a series of core flood experiments to investigate the effect of … WebThe stability of foam in porous media is extremely important for realizing the advantages of foamed gas on gas mobility reduction. Foam texture (i.e., bubbles per volume of gas) achieved is dictated by foam generation and coalescence processes occurring at the pore-level. For foam injection to be widely applied during gas injection projects, we need to … Web@article{osti_5393579, title = {Flow behavior of foam: a porous micromodel study}, author = {Owete, O S and Brigham, W E}, abstractNote = {The flow behavior of foam in porous micromodels has been studied visually using etched silicon wafers.
