METHOD FOR EVALUATING PLASTIC PRESSURE IN THE UNDERGROUND DISPOSAL OF HYDROCARBONS AND USED IN IT COMPUTER SYSTEM AND MACHINE READABLE

摘要

A method and system for estimating reservoir pressure in a hydrocarbon reservoir based on data from pressure measurements in production wells are described. Pressure measurement data is received from the wells in the field for a certain period of time and transmitted to a server that uses the specified pressure measurement data in the model of this well. Using a server-based model that uses borehole pressure measurement data, the well’s operating mode, such as production mode or shutdown mode, is determined. After determining the change in the operating mode, indicating a sharp change in the flow rate of the well, for example, corresponding to the event of well shutdown, data are collected for additional measurements of the borehole pressure until a steady state is reached. Pressure measurement data is used to determine the value of reservoir pressure, which is transmitted to the responsible field engineer or other user. A user change of the previously determined formation pressure value may be accepted, wherein the reservoir pressure value and the well model stored in the storage medium are updated accordingly.
