Assessment of technical solutions to minimise the impact of near-well condensate banking for production improvement in Hai Thach field
Abstract
Hai Thach gas condensate field (Block 05-2, Nam Con Son basin) is characterised by a complex geology with high temperature and high pressure. During the production process, gas recovery has declined due to condensate banking phenomenon. In order to minimise the impact of condensate banking on well productivity index and recovery, a full field compositional hydrodynamic model was constructed based on current geological model and updated reservoir and production data. Moreover, several technological and technical solutions were also studied and assessed for the purpose of improving well productivity index and increasing production capability in Hai Thach field.
