چکیده

Exploration of oil and gas seepages employing geochemical techniques has helped to discover new hydrocarbon resources across the world. Oil and gas exploration techniques had substantial advancements in the late 2000s. Numerous geophysical and geochemical techniques have been created and are constantly improving along with the advancement of digital technologies. Geochemical techniques are being used with remarkable success in the hydrocarbon exploration business to take informed decisions on project viability. These techniques contributed to determining the different hydrocarbon types, the degree of basin maturity, and the reliability of other petroleum system components. Combining precise geological and geophysical techniques with geochemical approaches can considerably improve the prospect chance of success. The current study offers a thorough discussion of geochemical exploration methodology and recommends an appropriate design process for geochemical surveys. It presents a methodical overview of various survey types as well as the advantages and disadvantages of geochemical techniques in comparison to other techniques used in hydrocarbon exploration.
