New Methods for the Prediction of Multiphase Flow through Wellhead Choke in Gas-Condensate Reservoirs
Abstract: Abstract The wellhead chokes are installed in order to stabilize oil and gas flow rates in production and operation disciplines. Most of the existing empirically derived correlations and predictive models to estimate choke performance have been proposed for oil fields production and operational conditions, and particularly production systems and reservoirs involved with condensation of the gaseous phase still suffer from a detailed consideration on the development of reliable predictive models. …

Plastic Pollution from River to Ocean: A Comprehensive Review in Indian Scenario
Abstract: Plastic represents a substantial environmental hazard, contributing to contamination of terrestrial,aquatic, and atmospheric ecosystems. This category comprises a diverse range of polymers. In the formof microplastics and nanoplastics, it can induce toxicity in water bodies. Plastic debris not onlyphysically pollutes freshwater, but also chemically, undergoing changes over time due to hydroclimaticeffects. Rivers serve as conduits, transporting plastics from minor tributaries to major rivers andultimately into the ocean, endangering marine life. …
