Formation fluid data based on measurements taken downhole under natural conditions is utilized to help identify reservoir compartments. A geological model of the reservoir including expected pressure and temperature conditions is integrated with a predicted fluid model fitted to measured composition and PVT data on reservoir fluid samples or representative analog. Synthetic downhole fluid analysis (DFA) logs created from the predictive fluid model can be displayed along the proposed borehole trajectory by geological modeling software prior to data acquisition. During a downhole fluid sampling operation, actual measurements can be displayed next to the predicted logs. If agreement exists between the predicted and measured fluid samples, the geologic and fluid models are validated. However, if there is a discrepancy between the predicted and measured fluid samples, the geological model and the fluid model need to be re-analyzed, e.g., to identify reservoir fluid compartments. A quantitative comparative analysis of the sampled fluids can be performed against other samples in the same borehole or in different boreholes in the field or region to calculate the statistical similarity of the fluids, and thus the possible connectivity between two or more reservoir regions.

Software and methods for extending preexisting objects to support persistence. One use of the present invention is to extend component object model (COM) objects to support persistence in a simple, predefined system. COM objects may be saved to persistence storage and loaded from persistence storage using user-provided save and load methods.

The object ID, together with the information stored in the Persistent Object Registry, may be used to restore a pointer value after loading. Objects may be saved by streaming the objects out and loaded by streaming the objects back into memory from a file.
