1. A method, comprising:

  • receiving seismic data for a hydrocarbon reservoir of interest;

    identifying geological features associated with a secondary gas charge from the seismic data, wherein the geological features are selected from a group consisting of one or more gas chimneys, bright spots and salt welds;

    determining the proximity of the geological features to the hydrocarbon reservoir of interest;

    receiving preliminary downhole fluid analysis (DFA) data from formations at or near the hydrocarbon reservoir of interest;

    analyzing the preliminary DFA data to determine the equilibrium state of the hydrocarbon reservoir and to confirm the secondary gas charge in the hydrocarbon reservoir; and

    determining whether to perform one or more additional DFA'"'"'s.
