... component alone. This enhanced reduction leads to better mobilization of residual oil. Both alkali and surfactant contribute to altering the wettability of the reservoir rock to more water-wet conditions, facilitating better oil displacement. The addition of polymer increases the viscosity of the injected...

... at the full field scale. The proposed correlation was tested for a narrow range of wettability (mostly mixed-wet) which calls for additional future research on broader wettability ranges as well as investigating multiple or two other phases including the gas phase instead of the water-oil phases...

... the reported values in literature (10 −8 to 10 −6 ). This work provides a new insight into the understanding of capillary trapping effect on residual oil using CDC in carbonates. The complications in carbonate rocks, including the complex nature of high heterogeneity, mixed-to-oil wettability, high...

.... as an analogue. The ensemble considers a range of interpretational scenarios and geomodelling techniques to capture the main components of its reservoir architectures, stratal geometries, facies, pore systems, diagenetic overprints and wettability variations across its platform-to-basin profile. Fully...

... different homogenous and heterogeneous rock-type distributions, wettability trends, as well as novel saturation modelling approaches that use dedicated software tools. Flow diagnostics capture the same trends in recovery predictions as the full-physics simulations. Importantly though, the total CPU time...

This study is part of our ongoing research in developing nanofluids for future or alternative enhanced oil recovery (Nano-EOR) method. Three different sizes of hydrophilic silica nanoparticles...

... angle measurement results of the wettability study. The Tagochi method was used to design wettability measurement experiments that span varieties of salinity combinations. The current study showed that coreflooding recovery has a clear relationship with the contact angle measurement of calcite plate. We...

... are realized not due to a reduction in the "technical/absolute" residual oil but rather due to improvement in the oil flow capacity (i.e. oil-to-water relative permeability ratio). Based on our results, we postulate that Smart-Water incremental recovery is triggered by the formation of a dual wettability state...

.... This is exacerbated by the presence of natural fractures and post-depositional dissolution. Furthermore, carbonate reservoirs tend to have variable wettability that impacts fluid flow which adds to reservoir uncertainty and renders managing WAG floods difficult. In this work, we examine the effect of rock...

Therefore, a detailed laboratory studies have been carried out with the aim at determining the detrimental effects of pore structure, wettability, capillary and imbibition forces, and permeability in tight sand gas and BCGA reservoirs. Based on experimental results...

... Abstract This paper discusses the impacts that rock wettability may have upon the production and recovery of oil with waterflooding in carbonate reservoirs and how it should be modeled. A broad review of the state of the art has been conducted surveying existing disagreements and knowledge gaps...

... Abstract Wettability plays an influential role in fluid flow behavior within a reservoir. Despite of its importance, it is not usually given the required significance during simulation studies. Different types of wettability may exist or co-exist within a reservoir which may change...

The first part of this paper presents CO 2 and N 2 injection experiments in a carbonate core sample. Two...

... and assuming identical interfacial tension between the different reservoir fluids, this paper suggests that the dynamic reservoir rock types, DRRTs, would only be a function of wettability for any SRRT. Thus by imposing wettability on the SRRTs, reservoir engineers should be able to generate the DRRTs...
