The significance of Joule-Thomson effect in petroleum industry applications has extensively been documented in the literature. In the first part of an extensive literature survey conducted on the significance of Joule-Thomson effect in petroleum fields Yadali Jamaloei and Asghari, 2015, this effect was presented in well testing, in multilateral/slanted wells, in drilling/completion/production operations, and in hydrate formation. In this article, the second part of this comprehensive review is presented, which consists of Joule-Thomson effect in CO2 injection into depleted natural gas reservoirs, in prediction of wellbore temperature profiles, and the influence of thermal stresses resulting from this effect on the wellbore stability. It is expected that this article will serve as a reference tool for the engineers interested in the Joule-Thomson effect in petroleum fields.
