Abstract: A computer receives a measured wetness of and a measured ?2H value associated with a test gas sample from a hydrocarbon formation. The measured wetness is a molar ratio of heavy gas compounds over a total gas within the measured sample. The computer receives calculated wetnesses calculated ?2H values associated with a gas samples taken from one or more analogous hydrocarbon reservoirs. The measured wetness received for the test gas sample is identified from among the plurality of calculated wetnesses. The computer determines a corresponding ?2H value from among the calculated ?2H values that corresponds to the measured wetness of the test gas sample. The computer determines a predicted sample VRo (vitrinite reflectance equivalent) for the test gas sample based on the corresponding ?2H value and a correlation of ?2H values to VRo values. Hydrocarbons are produced from the hydrocarbon formation based on the predicted sample VRo.
