Gas Condensate Banking: A Review of the Phenomenon, Accumulation, Mitigation Methods, and New Breakthrough

Abstract

This research presents a review related to condensate banking problem by describing the condensate phenomenon; condensate accumulation; current mitigation methods and its limitation. Then a new breakthrough method based on wettability alteration is introduced with an explanation on its mechanism and example of chemicals used. Next, new research ideas using nanoparticles as a wettability alteration agent is presented, and it is believed to be better than the chemical treatment alone as it modifieds the wettability surface from two aspects: surface free energy and surface roughness – while chemical treatment only reduced the surface free energy. In a nutshell, there is a significant gap of study in using nanoparticles as the wettability alteration agent in gas condensate reservoirs.
