Abstract :
A new chemical compound is developed at Petroleum University of Technology to enhance the
recovery of the free imbibition process and simultaneously hinder asphaltene precipitation. The
compound is tested on heavy oil samples from Marun oil field, Bangestan reservoir. The effects of
the chemical compound on viscosity, hydrocarbon composition, and average molecular weight of
the heavy oil are investigated. It is found that the substance dramatically reduces oil viscosity and
molecular weight and hinders the precipitation of asphaltene in the heavy oil. The results of free
imbibition tests demonstrate a significant recovery enhancement after oil reacts with the compound
and is used in water in an Amott cell. Finally, the new chemical compound causes a significant
reduction in surface tension and contact angle. This is verified by the molecular analysis of heavy oil
after reacting with this ionic compound.
