The TGT (Te Giac Trang) Field is located in the Cuu Long Basin of Vietnam. The main purpose of this study was to review lab PVT data and develop a fluid model for the TGT field, develop a detailed Equation of State (EOS) model, provide black-oil tables for reservoir simulation and to provide black-oil to compositional conversion tables. PhazeComp, the software exclusively used by PERA for fluid characterization and EOS model development is combined with the Pipe-It to provide a complete workflow incorporating the multi-steps needs and multiple post-processors.
