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 …

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 …

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