Summary: This study systematically investigated the diverting effect and influencing factors of a viscous fluid through a heterogeneous dual-core flooding experiment. The results showed that increasing the displacement pressure can improve the diverting effect, and using a viscous fluid as a stimulation fluid can enhance the acidizing effect. A relatively stable polymer solution is more suitable as a diverting agent.

Summary: This paper focuses on the stability, plugging capacity, conformance control, and oil recovery performance of surfactant-alternating-gas (SAG) foam in low-permeability reservoirs. Experimental results show that SAG foam is highly stable in micron-sized channels and porous media, making it suitable for enhanced oil recovery (EOR). The foam can passively adjust its diameter to match the pore size, providing excellent injectability and deep migration capacity. The SAG foam exhibits reduced plugging capacity but increased incremental oil recovery with decreased permeability. However, there is a limiting heterogeneity for SAG application, where the foam becomes ineffective when the permeability contrast exceeds a certain limit.

Summary: This study evaluated the diversion capacity of foam acid, VES acid, and foam-based VES acid through dual-core flooding experiments, finding that foam-based VES acid is most suitable for highly heterogeneous carbonate reservoirs. VES acid demonstrated stronger plugging ability in higher permeability cores and better stimulation effects in lower permeability cores, indicating its superior diversion ability compared to foam acid. Additionally, foam plugging and viscosity diversion showed a better synergistic effect in foam-based VES acid.

Summary: The study investigated the influence of different injection schemes on the enhanced oil recovery (EOR) of heterogeneous phase combination flooding (HPCF) after waterflooding. Results showed that the alternating injection (AI) scheme had the highest EOR, while the simultaneous injection (SI) scheme had the least. Visual flooding experiments also confirmed that the swept area of HPCF under the AI scheme was higher than that of the SI.

Summary: A numerical study was conducted to investigate the effectiveness of foam injection in treating production wells of heterogeneous reservoirs suffering from high gas oil ratio. The study revealed that the magnitude of Kv/Kh and the location of gas entry play a key role in selecting the optimal treatment scenario, resulting in a 60% reduction in GOR in a specific sector of a heterogeneous carbonate reservoir.

Summary: Bottom-water coning occurs in the middle and late stages of reservoir development, leading to a rapid increase in water cut and decline in oil production. Water plugging with nitrogen foam is effective for improving development during high water-cut periods. Foam and emulsion injection can result in improved oil recovery and decreased water cut in the reservoir.

Summary: Two empirical relationships were derived to predict the recovery factor in waterflooded layered oil reservoirs, using four independent variables and based on a global linear model. The expanded forms of the new correlations provided reliable estimates of recovery factor at water breakthrough time (RFBT) and at the end of project (RFEOP), while showing excellent fits when tested against simulation-generated data sets. The proposed correlations gave higher absolute percent difference compared to Guthrie-Greenberger and the API statistical study when tested against a single field data set.

Summary: Foam is applied in enhanced oil recovery to improve gas sweep and increase oil recovery. X-ray computed tomography is commonly used to evaluate foam performance in core plugs, but properties like bubble size and capillary pressure are difficult to measure. This study presents a novel technique for estimating water saturation and capillary pressure of foam in model fractures, revealing that water in foam mainly resides in narrow aperture locations, Plateau borders, lamellae between bubbles, and water films on glass walls.

Summary: This study characterizes the wettability of hydrogen and methane, as well as their mixtures, in subsurface reservoirs. The findings show that the wettability behavior of hydrogen and methane is similar, and their mixtures exhibit similar behavior to pure gas systems. The study also validates that under similar conditions, the contact angles of hydrogen and methane bubbles and their mixtures are comparable. This has implications for large-scale subsurface storage systems where buoyancy and capillary forces are the main factors affecting wettability.

Summary: Foam injection is a promising method in various applications, and several foam-simulation models have been examined to represent the minimum velocity for foam generation. These models show that an abrupt decrease in gas mobility can trigger foam generation. However, there are challenges in representing foam generation at high superficial velocities in numerical simulations, especially at the wellbore.

Summary: This paper describes how improved oil recovery techniques can reduce the CO2 intensity of oil production by efficient use of injectants. The study shows that the CO2 emissions associated with the injection of chemicals can be significantly reduced by reducing the water cut and improving the utilization factor. Implementing enhanced oil recovery methods earlier can also extend the lifetime of mature fields. CO2 enhanced oil recovery using captured CO2 from gas power plants can greatly reduce overall CO2 emissions of oil.

Summary: An understanding of how CO2 foam flows through a reservoir rock is beneficial for subsurface applications such as enhanced oil recovery and CO2 storage. This study investigates the behavior of supercritical CO2 foams flowing through a high-permeability Indiana Limestone by conducting core flood experiments. The foaming behavior and concentration response of two surfactants, a betaine and a sultaine, were studied and compared with N2. The results show that CO2 exhibits better foaming behavior at high foam qualities, while N2 generates stronger foam at low foam qualities.
