New Insights into the Mitigation of Asphaltene Deposition and the Utilization of Asphaltene Deposits
Asphaltene deposition is an ongoing flow assurance problem in the oil and gas industry that is associated with huge economic loss. Different aspects to this problem which includes asphaltene stability, asphaltene deposition and asphaltene characterization has been studied over the past few decades. …

Insights into asphaltene stability, aggregation, deposition and molecular structure
Asphaltenes are the heaviest, most polar, and most surface-active species of crude oils which are fairly stable in the oil; however, a small variation in the pressure, composition, and temperature can cause asphaltene phase instability and alteration in their solubility parameter and can …

Investigation of Asphaltene Instability Under Gas Injection in Unconventional Reservoirs and its Impact on Oil Recovery Performance
… these reservoirs often contain high levels of asphaltenes, which can lead to deposition and blockages in production wells and reduce the flow of hydrocarbons during gas enhanced oil recovery (GEOR) techniques. This study aims to experimentally evaluate the impact of miscible and immiscible …

Revitalizing Simulations of Colloidal and Interfacial Systems: From Atomistic Trajectories to Data-Centric Insights
… water-in-oil emulsions, chemical inhibition in asphaltene aggregation, and adsorption energy prediction. While each theme addresses unique challenges, they all contribute to quantitative understanding of interactions across scales, integrating structural, thermodynamic, and energetic …

Effect of roughness, microstructure, and chemistry on the environmental durability of structural alloys
… between the thermochemical properties of the asphaltene, the environmental conditions, surface preparation of the alloys, and the chemistry of the deposits. X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy allowed for the first time to pinpoint mechanisms for high …
