The findings of this study are expected to enhance the understanding of the application of smart waterflooding in carbonate reservoirs and the future perspective of hybrid application of water-based EOR processes. sedimentary rock waterflooding rock type...

... Abstract Smart water flooding is a promising eco-friendly method for enhancing oil recovery in carbonate reservoirs. The optimal salinity and ionic composition of the injected water play a critical role in the success of this method. This study advances the field by employing machine learning...

... Abstract In carbonate reservoirs, the establishment of a coherent correlation between petrophysical static rock type (PSRT) and petrophysical dynamic rock type (PDRT) schemes poses a formidable challenge due to its petrophysical complexity. Additionally, the interpretation of the dynamic...

... Abstract The objective of this study is to tackle the challenges associated with assessing the potential of carbonate reservoirs, especially when specialized logs such as image logs are unavailable. The primary aim is to introduce a novel workflow that integrates machine learning and data...

... of treatments could not improve oil recovery as reported in the literature. In this paper, we provide a machine learning based solution to improve this process. A comprehensive dataset that systematically compiles project data on surfactant treatments in carbonate reservoirs is constructed. Based...

This study investigates coning/channeling in an Atlantic margin pre-salt fractured carbonate reservoir using Embedded Discrete Fracture Modeling (EDFM) to gain a better understanding of the processes in fractured reservoirs. This study focused...

... acidizing fluid for carbonate reservoirs over a broad range of temperatures up to 300°F. As observed by HCl core flood tests, wormhole efficiency for the alternative acid also decreases with increasing temperature when compared with its performance at low temperature, but it showed reasonable results...

... Abstract Stimulating source rocks using hydraulic fracturing in unconventional source rocks is a common process. But such practice has not been followed when dealing with tight reservoir rocks. Tight carbonate reservoir rocks have in general been subjected to multistage acid fracturing...

... Abstract Foam injection has been promoted as a reliable method for improving the sweep efficiency in heterogeneous carbonate reservoirs by modifying the properties of the injected gas and hence, providing mobility control effect. However, the conditions of the Middle Eastern carbonate...

...Nanofluid stability Abstract Wettability alteration has been recognized as a key mechanism for enhanced oil recovery in oil-wet carbonate reservoirs. Nanoparticles can change rock surfaces from oil-wet to water-wet. However, there are multiple kinds of nanoparticles and different reservoir...
