Reservoir fluid types, 148 comparison

The information in Table V provides general comparisons but does not show details of the deviations at various temperatures and pressures. By studying the experimental and predicted K values on log K vs. log P plots at several temperatures, details of the deviations for each component at various conditions can be observed. Several examples of this type of comparison are shown in Figures 7-11. Knowing the percent deviation between the predicted and experimental K values does not provide a quantitative measure of errors in the predicted vapor-to-liquid ratio and the saturation pressure-properties which are important in reservoir-engineering calculations. The best indication of the accuracy of a K-value prediction method for reservoir fluids would be a detailed comparison of component K values as well as fractions of the fluid in the vapor and liquid phases and the saturation pressure. The latter comparisons are... 

A compositional kinetic model of hydrocarbon generation for a marine Type II source rock was developed based on data from closed-system non-isothermal pyrolysis experiments. The model predictions were tuned to a natural maturity sequence. The compositional data format chosen is compatible with the compositional resolution used in reservoir engineering, and allows a direct comparison of predicted compositions and phase behaviour to PVT data of natural fluids.
