Mitigating Asphaltene Deposition in CO2 Flooding with Carbon Quantum Dots

open access: yesEnergies
Carbon capture, utilization, and storage (CCUS) technology has emerged as a pivotal measure in mitigating global climate change. Notably, CO2-EOR is esteemed for its dual function of sequestering CO2 and enhancing oil recovery.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and

Enhanced asphaltene degradation using piezocatalytic technology: A novel approach for sustainable oilfield operations

open access: yesResults in Engineering
Asphalt or oil spills containing asphaltene can contaminate soil, water bodies, and ecosystems. Natural balances are disrupted by this contamination. Asphaltene contaminates water sources such as rivers, lakes, and aquifers, making them unfit for human ...
