Abstract
The use of equations of state (EOS) to model fluid properties is necessary in order to have an internally consistent set of PVT properties, which is essential, especially, when it is desired to use compositional simulators to model two-phase reservoirs. In this article, the 3-parameter Peng-Robinson equation of state along with single carbon number (SCN) splitting of the C7+ fraction are used to model a major onshore reservoir in Abu Dhabi that has horizontal and vertical fluid properties variations. Extensive screening and checking of PVT data of the field was necessary to develop this model. Also, extensive verification of the developed model was accomplished by comparing its results to data external to the model. Results of this article indicate the capability of using multiple well PVT analysis within the three-parameter Peng-Robinson EOS to model complex two-phase reservoirs such as this one. We describe the process of building up the model and the challenges involved in performing this task, which include proper selection of representative experimental data to build the model, along with extensive screening and data quality these data, and the model verification so that we have the confidence that one EOS model that can predict the reservoir fluid PVT properties.
