... caused by the temperature increment. During heating, different parameters were measured in order to understand what occurs to the porous medium while it is subjected to changes of temperature. The measurements include pore volume, total volume and permeability at different stages during the heating...

... of occurrence of steam channeling is significantly increased when the permeability difference is greater than 4. The location of steam channeling is high permeability layer and small well spacing. The original calculation method of steam channeling volume can accurately predict the dosage of the plugging agent...

... 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...

... 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...

... 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...

... the reserves could be increased. Also, a change 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...

... is a mechanistic model based 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...

... We determinated rock type for each sample analyzed to which it belongs, using the methodology developed by Winland, which suggested an empirical relationship based on numerical multiple regression analysis, by relating porosity to air permeability and Pore-Throat-Size to mercury saturation of 35...

... in a partial penetration test; thus, some recommendations were drawn to reduce wellbore storage and ensure the hemispherical flow regime appears, as longer as possible during the test, to measure vertical permeability. A partial penetration test was carried out in an exploratory well supported...

... recovery factor, the foam injection can be mentioned. 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...

... properties of set cement systems is mandatory. Chemical stability, compressive strength, and permeability are commonly the main parameters determined for oilfield cement systems. The knowledge of these properties is most often enough to estimate if a cement system will maintain well integrity. However, some...

... to evaluate the performance of the SBH process in comparison with the SAGD process for three different reservoir models (Geomodel I, II and III) using numerical simulation. Geomodel III is the cleanest (highest average permeability) and most homogeneous of the three reservoir models. Geomodel II has...

... Abstract Heavy-oil carbonate reservoirs are complicated to produce. Heavy-oil saturated fractured limestone formations present tremendous completion, stimulation and production challenges because they commonly contain thick completion intervals with extreme permeability ranges. In Mexico...

... Selective steam injection is presented as an alternative that improves the development of a field, increasing oil recovery intensifying the injection of steam into formations with medium and low permeability and in turn reducing the steam channeling. Abstract Steam injection is one of most...
