Practical Model for Predicting Pressure in Gas-Storage Reservoirs

Presentation of a new way to calculate the convolution integral on which the pressure variations in a gas-storage reservoir depend. This method is much quicker than the classic ones; it has been implemented in a program called PREPRE (Gaz de France), usable on microcomputers. The model is capable of forecasting the evolution of pressures in main zones of interest. The data required for the model ― past production/pressure history ― are matched by a special algorithm that automatically calculates the main reservoir parameters used as bases for future projections.
