Exploring for oil and gas takes a lot of money and know how to pull off as it requires first a comprehensive understanding of the fundamentals of petroleum Geology. Oil and gas are, after all, essential petroleum resources that are found deep within the earth’s crust, although there are cases where they may be found on the surface as well, but not in abundant commercial quantities.


Liquid oil and liquid natural gas underneath are found in porous and permeable rocks (also called reservoirs) that have collected these precious materials for thousands of years. There are four essential types of geologic features that contain oil and gas deposits, namely:

* Oil and gas source rocks

* Reservoir rocks

* Seals

* Traps
