Asphaltene is one of the polar and heavy fractions of crude oil that is complex from a
molecular perspective. For this reason, the interaction between asphaltene molecules and …

Power ultrasound, as an emerging green technology has received increasing attention of
the petroleum industry. The physical and chemical effects of the periodic oscillation and …

The research on the flowability of waxy oil has spanned more than a century and is still
attracting much attention. How to improve the flowability of waxy oil to ensure safe and …

The upgrading of heavy oil is one of the most important processes in heavy oil recovery due
to the low quality of these types of oil. In this study, the effects of nanomaterials of Fe …

This paper investigated the effects of microwaves (MW) on Wax Appearance Temperature
(WAT), the shape and morphology of wax crystals, and the content of elements in crude oil …

In this study, the influence of ultrasonic waves on the viscosity and thermal behaviour of a
crude oil with high asphaltene content at different irradiation times and powers/frequencies …

This study examined the effects of microwave on Sarvak heavy crude oil sample from a
reservoir in southwest Iran in a Fischer assay and heated by microwave for 2 min time steps …

This study investigated the effect of different surface modifications on the microwave
absorption performance of new synthesized MWCNT-Fe 3 O 4 nanohybrid. MWCNT-Fe 3 O …

The asphaltene deposition throughout the reservoir's life (primary, secondary production,
and enhanced oil recovery) is natural. Different methods are used to deal with the problems …

Condensate formation near the wellbore is considered as one of the challenging problems
affecting the production from a gas reservoir. Two types of mechanical and electromagnetic …
