Surface water and groundwater contamination by heavy metals is a global serious concern,
which despite its well-known character, still lacks a decisive application to tackle its harmful …

Nanoparticles (NPs) have been recently recognized as effective asphaltenes adsorbents
and deposition deterrents. The objective of this work is to provide a critical review and …

In this work, we evaluate the effect of nanoparticles and nanofluids as viscosity reducers for
heavy crude oil (HO). The effect of alumina, silica and acidic silica nanoparticles was …

In Colombia, the estimated reserves of crude oil are approximately 2.0 thousand million
barrels, decreasing by approximately 13% in the last year according to the National …

The primary objective of this study is to investigate the effects of SiO 2 nanoparticles on
improving the rheological behavior and inhibition of the thermal degradation of hydrolyzed …

Heavy and extra-heavy oils generally exhibit high viscosity, which is detrimental to their
production, transport, and refining. The oil and gas industry has thoroughly investigated the …

The main objective of this study is to evaluate the effect of particle size and surface acidity of
synthesized silica gel nanoparticles on the inhibition of formation damage caused by …

The increasing demand for fossil fuels and the depleting of light crude oil in the next years
generates the need to exploit heavy and unconventional crude oils. To face this challenge …

This study investigated the mechanisms and performance of SiO2 nanofluid for enhanced oil
recovery (EOR) in low-permeability cores. Three-phase contact angles for quartz/oil/brine …

One of the most common sources of formation damage in tight reservoirs of gas-condensate
is condensate banking. The condensate level on the porous media reduces the effective …
