This work presents a parametric analysis and practical comparison of four cubic equations of state (EoS): Soave – Redlich – Kwong (SRK), Soave – Redlich – Kwong – Peneloux (SRKP), Peng – Robinson (PR), and Peng – Robinson – Peneloux (PRP) using a QA/QC-verified PVT dataset from the Volve field provided by the technical literature. The aim is to compare the results of four EoS-based PVT simulations with experimental data, and to correlate the deviations to the physical meaning of the EOS parameters. The first step in the workflow was the validation of the bottom hole sample reliability through a material balance assessment.
