Equalizing hydrocarbon reservoir pressure

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations for equalization of hydrocarbon reservoir pressure, comprising:

• executing a hydrocarbon reservoir model simulation to distribute gas among available gas injectors associated with a hydrocarbon reservoir;
• using the result of the executed hydrocarbon reservoir simulation, executing streamline tracing to calculate hydrocarbon flow fields;
• using the results of the executed hydrocarbon reservoir simulation and the executed streamline tracing, executing a reservoir pressure equalization (RPE) algorithm to distribute an amount of gas according to an injection strategy to satisfy an assigned voidage replace ratio (VRR) for each region of the hydrocarbon reservoir;
• performing post-processing of the results of the RPE algorithm;
• and
• using the result of the post-processing, performing gas injection in the hydrocarbon reservoir with the available gas injectors.
