Story of Oil & Gas - Origins
Natural Gas and Oil seepages are known to many civilizations (Eg. Jwalamukhi)
Col. Edwin Drake discovered modern oil at Titusville, Pennsylvania in 1859
Digboi in Assam is the world’s first oil field discovery outside USA (First in India)

Origin of Petroleum – Scene-1
Oil is a fossil fuel. It was formed more than 300-10 million years ago. Some scientists say that tiny diatoms is the source of oil. Diatoms are sea creatures the size of a pin head. They do one thing just like plants; they can convert sunlight directly into stored energy

Origin of Petroleum – Scene-2
In the graphic on the left, as the diatoms died they fell to the sea floor (1). Here they were buried under sediment and other rock (2). The rock squeezed the diatoms and the energy in their bodies could not escape. The carbon eventually turned into oil under great pressure and heat. As the earth changed and moved and folded, pockets where oil and natural gas can be found were formed (3).

Petroleum E&P Business Overview
E&D is essentially Centered around managing information– Quality– Completeness– Auditability
Significant value accretion
E&D is essentially obtaining “reliable” information on O&G occurrence and recoverability
