Given the combination of rising global energy demand and the decline in conventional
crudes, heavy crudes are generally considered to be the future energy resource. In many …

Waxy crude oil emulsions exhibit gelation behavior, with nucleation observed within a
certain temperature range. A kinetic model was developed and validated based on the …

Responsive emulsions can be “switched off” by external environmental stimulus or trigger,
allowing a simple and effective demulsification approach and thus attracting much attention …

Transportation of crude oils has recently received more attention than in the past; the main
reason for this is because of the changes that petroleum production has experienced. The …

Asphaltene flocculation and deposition from petroleum fluids may cause severe formation
damage and flow assurance challenges. Flocculation occurs when asphaltene aggregates …

It has previously been shown that in situ upgrading of heavy oil by toe-to-heel air injection
(THAI) can be augmented by surrounding the horizontal production well with an annulus of …

This article thoroughly evaluates the performance of a synthesized surfactant as an
emulsifier for the preparation of an Indian heavy crude oil-in-water (o/w) emulsion to …

Heavy oil gathering and transportation system is increasingly attention and the realization of
intelligent control has become the oilfield development direction and trend in the future. In …

A series of water-soluble terpolymers, poly (acrylamide/N-vinylpyrrolidone/N-(acrylamido
propyl)-N, N-dimethyl, N-cetyl ammonium bromide)(ANAs), were synthesized through free …

This work investigates the performance of isooctyl glucoside (APG08) as an emulsifier for
the preparation of a Karamay heavy crude oil-in-water emulsion to facilitate its pipeline …
