1. A method comprising:
receiving, by a computer system, a dataset comprising calculated wetnesses of and calculated δ2H values associated with hydrocarbon gasses;
determining, by the computer system, a reference line from the dataset;
plotting, by the computer system, the reference line on a plot;
plotting, by the computer system, a sample wetness of and a sample δ2H value associated with a received gas sample received from a hydrocarbon formation on the plot with the reference line to produce a plotted point;
increasing, by the computer system, a δ2H value of the plotted point to provide an adjusted plotted point so that a δ2H value of the adjusted plotted point matches the reference line;
determining, by the computer system, an adjusted δ2H value from the adjusted plotted point, wherein the adjusted δ2H value is the δ2H value of the adjusted plotted point; and
determining, by the computer system, a predicted sample VRo (vitrinite reflectance equivalent) for the received gas sample based on the adjusted δ2H value and a correlation of δ2H values to VRo values, the VRo values correlating with gas maturity.
