... underlying thermal composite oil recovery. Our findings show the presence of wall-adhering oil films and filamentary flows during low-temperature hot water flooding. Specifically, at 150°C, the phenomenon of oil-water slug displacement occurs. At 350°C, steam manifests as isolated, nebulous clusters within...

... Abstract The primary objective of this research is to investigate the dynamic immiscible viscous fingering that occurs during grading viscosity polymer flooding in a heterogeneous core using simulations. The study also aims to assess the enhanced oil recovery (EOR) performance, including...

... Abstract This paper presents the results acquired during first laboratory-scale chemical flooding evaluation for a giant waterflooded oilfield in Kazakhstan. A carefully-designed chemical flood recipe involves the injection of a mixture of surfactant and alkali/nanoparticles followed by polymer...

... Abstract Foam flooding has been widely studied and implemented in recent years to alleviate reservoir heterogeneity and increase oil recovery. Previously, foam flooding was employed for conformance control and improving sweep efficiency, and little attention was paid to displacement efficiency...

... assisted by nanoparticles for EOR in a heavy oilfield is presented in this paper. The extent to which the gas EOR optimization techniques can lower gas breakthrough while boosting oil recovery was investigated through a series of numerical simulations. The aim of this study is to model foam flooding...

.... This paper presents a method for screening and increasing efficiency of gas EOR methods based on microfluidic studies and for studying the influence of various factors on the oil displacement process. Such technology can be used on par with traditional core flooding tests, reducing time, cost, and the amount...

... water-wet, which increased oil recovery. As the salinity decreases, the oil recovery increases. This was determined by conducting water-flooding experiments on four cores. Performing another four experiments using foam and different brines revealed that the lower brine salinity, the greater the oil...

... Abstract It is a well-known EOR mechanism that residual oil in swept zone after water flooding (including oil drops, films and clusters) can be mobilized by low interfacial tension (IFT) during surfactant flooding. The aim of this work is to investigate if trapped oil in low-permeability zone...
