Foam mobility in heterogeneous porous media
WebSummary The feasibility of foam enhanced oil recovery (EOR) for a heterogeneous carbonate reservoir in the Middle East with medium temperature (55°C) and high formation salinity (above 16% TDS) is presented here. The promising surfactant formulations were firstly evaluated based on solubility tests and bulk foam tests. Afterwards, a series of … WebApr 19, 1998 · When the heterogeneous layers are in capillary communication and cross flow is allowed, foam fronts move at identical rates in each porous medium as quantified …

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 … 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 …
WebAbstract Foams are widely used in the oil industry for drilling, fracturing, and acidizing, and for sweep improvement in gas-injection EOR. All these applications rely on reducing gas mobility in rock to or nearly to zero in the presence of foam. Models of these foam precesses must confront two challenges: the changing texture (bubble size) of foam and …
