... by the iron content (Fetot): from 0.12 to 1.14 mass%., and by the form of iron in minerals: siderite (Fe siderite ), pyrite (Fe pyrite ), and iron-bearing clays like montmorillonite (Fe clay ). Fifty seven samples of asphaltenes have been studied. Asphaltenes were extracted from produced and residual oils...

... Abstract Conventional Capillary Number theory predicts that residual oil will not be mobilized until a critical capillary number (2E-05) is exceeded. This theory was tested to determine residual oil saturation mobilization after the forced water imbibition. In the literature, high residual oil...

... of polymer to sodium lactate equal to one. The other gel system tested was composed of 5% low molecular weight polyacrylamide with a ratio of 1:12 chromium to polymer. Experiments were conducted at 1200 psi and 40 °, with and without the presence of residual oil in order to investigate any role the residual...

... by waterflooding or immiscible gas injection. This paper depicts a pore level visualization study, through visual observation of foam flooding in transparent etched-glass micromodels. In this study the effect of aqueous foam flooding and polymer enhanced foam flooding on residual oil recovery efficiency...

... Abstract In waterflooded reservoirs, it is still possible to recover a significant amount of residual oil by enhanced oil recovery. Immiscible water-alternating-gas (WAG) injection is one of the well-established methods for improving oil recovery. However, the mechanism of three-phase flow...
