Abstract Nuclear Magnetic Resonance experiments were used to study the relationship
between the structural type (continental or archipelago) and aggregation properties of three …

Asphaltene precipitation and deposition are considered major problems in primary,
secondary and tertiary phases of oil production. These phenomena can cause partial or …

Blending of different crude oils is currently carried out in the petroleum industry. However,
under certain process conditions, ie, pressure, temperature, flow regime, composition, etc …

Recent studies (eg, Selby and Creaser, 2005) have raised the intriguing possibility that the
evolution of oil can be dated using the Re–Os radioisotope system. However, in order to …

In this study, the asphaltene particle aggregation process is studied and effects of
asphaltene concentration, n-heptane to toluene volume ratio, type and concentration of …

In this study, the asphaltene deposition and the fouling layer growth are modeled using the
multi-fluid approach. The crude oil is considered as a multi-species fluid which the …

In order to understand the structure of asphaltene after its disaggregating by chemical
processing, a comprehensive study for exploring the structural changes of asphaltene after …

Asphaltenes from three crudes were precipitated with a mixture of n-heptane and toluene,
the size of the particles formed under different solvent mixtures and different agitation …

Przedstawiono porównanie metod pomiarowych dotyczących oznaczania stabilności i
kompatybilności rop naftowych celem ułatwienia przerobu ropy naftowej i paliw ciężkich …

Unconventional resources such as tight oil and bitumen do not yield to conventional
production processes and are difficult to produce economically. The use of solvents to …
