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 …

Adsorption of asphaltene onto mineral or metal surface is an undesirable process with
several adverse effects such as wettability alteration, fouling pipelines/equipment …

Asphaltene adsorption at solid surfaces is a ubiquitous phenomenon that begins within the
production well and continues through the entire production chain. It is generally an …

Biochar (BC) derived from bamboo pyrolysis and its modified forms were treated with
chemical methods (oxidation either by KMnO4 or HNO3 and base treatment with NaOH) 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 deposition of asphaltenes is one of the most difficult problems to overcome in oil
production and processing. The presence of asphaltenes in crude oil, and consequently, the …

Preventing asphaltene-related damage in hydrocarbon reservoirs is an important concern.
Many investigations have been performed on asphaltene and its effects and how to reduce …

High asphaltene content in heavy crude oil normally generates adverse rheological
properties that affect the flow through the reservoir, preventing optimal hydrocarbon …

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 …
