In this communication, a novel approach for combined Enhanced Oil Recovery (EOR) and asphaltene inhibition is proposed employing a New Class of Asphaltene Inhibitor (NCAI).

Following primary and secondary oil production, appropriate EOR techniques can increase oil recovery. Gas injection is commonly used, however there are risks associated with asphaltene precipitation and deposition which could result in flow assurance concerns in addition to changes in wettability.

This work investigates the effect of a newly developed AI on the wettability of synthesized substrates. An Environmental Scanning Electron Microscopy (ESEM) technique is utilized for monitoring the wettability alterations of the substrates caused by NCAI. This research also presents adsorption equilibrium and kinetics data for the NCAI on sandstone rocks. Batch experiments are conducted at various temperatures (from 25 °C …
