Nguyen, SPE, The … 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 …

WebApr 6, 2024 · Foam generation Microfluidics Porous media Nanoparticles 1. Introduction Foam is injected into the subsurface to reduce gas mobility by increasing its effective viscosity and to divert the gas to low permeability zones ( Rossen, 1996, Ransohoff and Radke, 1988, Conn et al., 2014, Li et al., 2010 ). WebApr 28, 2024 · Foam injection performance in porous media depends on several factors including foam texture, media characteristics, injection scenarios, etc. Several attempts …
WebFoam Generation in Homogeneous Porous Media Abstract In steady gas-liquid flow in homogeneous porous media with surfactant present, there is often observed a … WebJun 1, 1994 · A foam is a dispersion of a large volume of gas in a continuous liquid phase, stabilized by surfactant. Foams can improve sweep efficiency and oil recovery in gas-injection enhanced oil recovery projects. An important issue for these foam processes is the ease of foam generation in porous media.
WebSummary In most of transient foam core-flood studies, it is observed that multiple pore volumes of foam injection are needed before reaching the steady-state. The pore volumes needed appear to change with the degree of homogeneity of the porous media, orientation of the core, type of surfactant and the total injected flow rate. This is contrary to the foam … WebOct 1, 2002 · Earlier research on foam generation is extended here with extensive data for a variety of porous media, permeabilities, gases (N2 and C02), surfactants, and …
WebApr 11, 2016 · The results indicate once foam is generated in porous media, it is possible to maintain strong foam at low injection rates. This makes foam more feasible in field applications where foam generation is limited by high injection rates (or high pressure gradient) that may only exist near the injection well.
