“…B-PPG particles are a kind of oil flooding agent with viscoelasticity and partially cross-linked and branched structures in their molecules. When B-PPG is dispersed in water, a heterogeneous polymer suspension is formed. , Through core flooding experiments, Sang et al found that B-PPG can undergo temporary plugging, deformation, and migration. B-PPG can effectively plug the layer of high permeability, allowing fluid to flow toward the layer of low permeability and expanding the spread area effectively.…”

In the later stage of water flooding, the water cut of the reservoir is high and the water channeling of the interlayer is severe, leading to the invalid or inefficient circulation of injected water and to poor development results. However, the three-phase foam (TPF), which combines the advantages of foam and particles, is strongly applicable for high water cut reservoirs. To explore the plugging and profile control mechanisms of the TPF and the degree of improving oil recovery, branched-formed particle gel (B-PPG), surfactant DLY-05, and N2 were mixed to form the TPF. The system was used in two-dimensional flooding experiments consisting of homogeneous, positive rhythm, reverse rhythm, and high-permeability channel models. Quantitative and qualitative analyses were carried out with the displacement phenomenon and the dynamic parameters of oil production. Such a water cut, production pressure difference, and recovery factor were analyzed in detail. The results show that the TPF has good adaptability to four high water cut models. When TPF is injected, the water cut of the produced liquid is significantly reduced, and the production pressure difference and oil recovery factor are significantly increased. The decrease in water cut ranges from 17.26 to 22.27%, corresponding to an increase in the oil recovery factor of 20.63 to 28.28%. The dynamic changes in the model flow line and flow field in different flooding stages show that the TPF can control the profile and flooding oil. In addition, when flexible particles deform and enter the small pore throat, residual oil is squeezed and carried out. The research results provide a theoretical reference for the application of a three-phase foam in actual reservoirs. The study of TPF in a high water cut reservoir provides a reference for its application in an actual reservoir in the future.

The growing interest in phase-change materials (PCM) is related to their possible role in thermal energy storage and thermal management. The choice of materials depends strongly on the required temperature range, whereas the latent heat of solid-liquid phase transition has to be as high as possible. Among other organic PCM, sugar alcohols have gained some attention due to their availability and certain advantageous properties. However, the thermal processes in these materials still require investigation.In the present work, we focused on the materials with solid-liquid phase change within 80 – 100 °C. A comprehensive literature survey was conducted to elucidate the available sugar alcohols relevant to this range. It was found that the use of pure materials of this type is not very practical, because of their scarcity in the required range and their specific features, like difficulties with crystallization and solidification. On the other hand, based on the literature, we have discerned three mixtures of erythritol with other organic materials. In all those cases, it is remarkable that while the components commonly have rather high melting temperatures, the eutectic mixtures had the phase transitions in the required range. Still, each of these mixtures has its own peculiar features, especially at cooling and solidification. An extensive experimental study was performed to provide detailed visualization of these major processes.

Phase change materials (PCMs) used for thermal energy storage (TES) have shown to be particularly promising, especially in light of the growing need for a wide variety of energy-related applications. This article discusses the usage of packed beds made from phase change materials in solar energy storage devices for variable temperature environments. The primary heating/cooling technologies and associated thermal energy storage difficulties have also been examined from the perspective of engineering applications. The packed bed’s history from a thermodynamic perspective, the temperature dispersion inside the packed bed, and several design factors that influence its performance are all covered in the brief description of the packed bed. Energy and exergy efficacy are the foundations of its analysis. The article delves into numerous thermal energy storage methods, with phase change materials being the primary topic and a beneficial means of storing thermal energy. In addition, phase change materials also keep latent thermal energy during phase transitions at almost constant temperatures.
