Then a new mitigation method based on wettability alteration is introduced with an explanation on its mechanism and example of chemicals used. Next, new researches using nanoparticles as a wettability alteration agent is presented, and it is believed to be superior to the chemical treatment alone as it modifies the surface wettability from two aspects: surface energy and surface roughness {\^a}?? while chemical treatment only reduces the surface energy. In a nutshell, there is a significant gap of study in using nanoparticles as the wettability alteration agent in gas condensate reservoirs. {\^A}{\copyright} 2019 Elsevier B.V.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85071670945&doi=10.1016\%2fj.petrol.2019.106431&partnerID=40&md5=fa124321ba819a9506cf0600fb01592f}, issn = {09204105}, author = {Ganie, K. and Idris, A.
