Method to enhance exploration, development and production of hydrocarbons using multiply substituted isotopologue geochemistry, basin modeling and molecular kinetics

A computer system for exploration, production, and development of hydrocarbons comprising:

• a processor;
• memory in communication with the processor;
• and
• a set of instructions stored in memory and accessible by the processor, the set of instructions, when executed by the processor, are configured to:
• obtain information associated with a hydrocarbon sample;
• analyze the information for a geochemical signature, wherein the geochemical signature comprises one or more of a multiply substituted isotopologue signature and a position specific isotope signature;
• determine one or more of type of alteration and extent of alteration, wherein the determining comprises comparing one or more of the multiply substituted isotopologue signature and position specific isotope signature of isotopes of different species of hydrocarbon compounds;
• and
• develop or refine an exploration, development, or production strategy based on the determined one or more of type of alteration and extent of alteration.
