Paper presented at the International Petroleum Technology Conference, March 23–April 1, 2021
Paper Number: IPTC-21491-MS
... Abstract Condensate banking in natural gas reservoirs can hinder the productivity of production wells dramatically due to the multiphase flow behaviour around the wellbore. This phenomenon takes place when the reservoir pressure drops below the dew point pressure. In this work, we model this...
