... of steam channeling is established as follows: V = α × β × l × h × D × ϕ V : The volume of steam channeling, m 3 ; α : The proportion of high permeability zone in horizontal section; β : The connectivity coefficient; l : horizontal section, m; h : The thickness of oil layer, m...

... of petroleum engineers oil recovery factor permeability Introduction At the beginning of the productive life of an oil field, hydrocarbon production is mainly due to the natural energy in the reservoir. However, with the continuous oil production, this natural energy decreases, and the oil production...

... and depends on the height above the free water level, the interfacial tension, Oil-water fluid density, absolute permeability and effective porosity. In order to define this function, capillary pressure data from oil-water system of drain cycle from special core analysis were used. The core data were modeled...

... permeability seawater water injection interaction Introduction The use of (smart) water injection as a natural wettability modifier has recently gained significant attention. By definition, smart water has been adopted as the idea of changing the injected brine composition in order to enhance oil...

... in the permeability appears due to the temperature increases. The present study was focused in oil matrix extraction and in situ oil upgrading from a naturally fractured reservoir of heavy oil as a result of a hot fluid injection with nano catalyst. Moreover, the effects of capillary pressure, mobility, viscous...

... on interpolation of relative permeability curves parametrized with respect to the local capillary number. The second model requires tracking a thermodynamically stable phase known to exist at water-oil ultralow interfacial tension, namely a microemulsion. To perform this analysis, two sets of chemical coreflooding...

The foam may be used as a selective block agent of the reservoir, which reduces the effective permeability zones already swept with high permeability. A widely used tool for this purpose is the simulation of petroleum reservoirs, which through...
