Binary diagrams using compositional and isotopic data from the wells PTRA-1, PTRA-2, PTRA-5, and PTRA-14. (a) Correlation of gas wetness (C2-C5/C1-C5) in percentage versus the concentration of methane; (b) Correlation of gas wetness versus the proportion of helium normalized with the sum of hydrocarbons; (c) Correlation of the ratio ethane/methane versus the carbon isotopic ratio of methane.
