| 1. A method for analysis of reservoir fluids in connection with a drilling operation, comprising:
determining composition and isotopes of injection fluids injected into a wellbore during a drilling operation and production
fluids recovered from the well bore during the drilling operation; and
characterizing reservoir fluids of a reservoir intersected by the wellbore based on the composition and isotopes of the injection
fluid and the production fluid.
