PVT Calculator ^Popular

PVT (Pressure/Volume/Temperature) data play an indispensable role in reservoir engineering calculations. GEMINI hosts different reservoir engineering tools to analyze DST data, calculate volumetric reserves in place and initiate some material balance calculations. PVT data is integral to each of these calculations. PVT data can be generated from laboratory measurements on representative fluid samples from the reservoir. However, it is not uncommon for the user to lack access to fluid samples from the reservoir of interest or laboratory measured PVT data sets.

Extensive research has resulted in a huge body of published literature on the physical properties of reservoir fluids. The recent past has seen a move towards the standardization of laboratory procedures for analyzing fluid properties and significant advances in leveraging the equations of state to calculate gas-liquid equilibria. Also, understanding about the chemical nature of petroleum fluids has matured. As a result of these advances, numerous correlations have also been developed to estimate, often with reasonable accuracies, different PVT properties of reservoir fluids. Available equations express these tabular and graphical correlations in forms that can be easily programmed into simple input-output modules.

In the absence of measured PVT data, it is common practice in the industry to resort to standard published correlations to estimate the PVT properties of reservoir fluids based on a minimal set of known data. The PVT module of GEMINI helps the user to calculate some of the basic PVT properties of oil and gas, that are required as inputs to DST analysis, volumetric and material balance calculations, given a limited set input data.
