The injected fluids in secondary processes supplement the natural energy present in the
reservoir to displace oil. The recovery efficiency mainly depends on the mechanism of …

Chemicals are a pivotal part of many operations for the oil and gas industry. The purpose of
chemical application in the subsurface reservoir is to decrease the mobility ratio between the …

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 …

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 …

Utilization of the abundant heavy crude oil resources has been accepted as an effective
approach to tackle the shortage of light oil supply in the coming decades. However, the high …

Heavy oil is estimated to account for about 70% of the remaining oil reserves and
considered as the most promising and readily available oil resource to meet energy …

Many in situ recovery methods have been developed to extract heavy oil and bitumen from
deep reservoirs. The “underground refinery” approach using a nanosize ultradispersed (UD) …

The effects of surface acidity and basicity of metal oxide nanoparticles on the
thermodynamics of asphaltene adsorption were studied. Three different categories of metal …

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 …
