HYBRID RESERVOIR BRINE MODEL

摘要

A method of estimating saturation conditions of reservoir brines in an underground reservoir includes: receiving data representing a temperature of the brine; determining if the temperature is greater than a preset value; and selecting either a first method or second method, different than the first method, of calculating the saturation conditions based on the determination. The first method is selected when the temperature is greater than the preset value and the second method is selected when the temperature is less than the preset value.

1. An apparatus for estimating saturation conditions of reservoir brines in an underground reservoir, the apparatus comprising:
a sensor for measuring a temperature of the brine; and a processor, the processor configured to:
receive data representing the temperature;determine if the temperature is greater than a preset value;select either a first method or second method, different than the first method, of calculating the saturation conditions based on the determination,wherein the first method is selected when the temperature is greater than the preset value and the second method is selected when the temperature is less than the preset value; andbased on results of the first or second method, form the saturation condition estimates utilizing an equation of state (EOS) model.
