It is demonstrated that an increasing impact of anthropogenic factors becomes characteristic of the modern sanitary state of water reservoirs in rural areas. Priority indices of water quality in rural water reservoirs are proposed. Proceeding from the data thus obtained there is recommended a set of water-protective measures aimed at raising safety of water management conditions.

Machine learning and AVO class II workflow for hydrocarbon prospectivity in the Messinian offshore Nile Delta Egypt.
Sci Rep

Rashpetco Company, Cairo, Egypt.
This study presents a comprehensive workflow to detect low seismic amplitude gas fields in hydrocarbon exploration projects, focusing on the West Delta Deep Marine (WDDM) concession, offshore Egypt. The workflow integrates seismic spectral decomposition and machine learning algorithms to identify subtle anomalies, including low seismic amplitude gas sand and background amplitude water sand. Spectral decomposition helps delineate the fairway boundaries and structural features, while Amplitude Versus Offset (AVO) analysis is used to validate gas sand anomalies.

Sichuan section mainstem (SSM) in the upper Yangtze River (UYR) plays a crucial role in protecting the aquatic environment of the UYR and ensuring a safe water supply to the Three Gorges Reservoir. The impoundments of cascade reservoirs on the lower Jinsha River have significantly influenced sediment regime and phosphorus (P) transport in the SSM. This effect on water quality and safety remains poorly understood.

Microplastic pollution poses a significant threat to coastal ecosystems worldwide. Despite its widespread occurrence, knowledge on the prevalence and fate of microplastics across food webs is limited. To bridge this gap, we conducted an extensive study on microplastic contamination in mudflats, mangroves, and sand beaches being key habitats for wintering shorebirds on the west coast of India.

Dissolved organic matter (DOM) is the primary precursor of disinfection products (DBPs) during chlorination. However, the compositional characteristics of DOM transformation during the chlorination process in different source waters and its relationship to cytotoxicity remain understudied. Here, we used high-resolution mass spectrometry to evaluate chlorination-induced molecular-level changes in DOM derived from different surface water sources.

Enhancing oil recovery in sandstone reservoirs, particularly through smart water flooding, is an appealing area of research that has been thoroughly documented. However, few studies have examined the formation of water-in-heavy oil emulsion because of the incompatibility between the injected water-folded ions, clay particles, and heavy fraction in the oil phase. In this study, we investigated the synergistic roles of asphaltene and clay in the smart water flooding process using a novel experimental approach.
