Light(API gravity > 31)
Intermediate(API gravity 22-31)
Heavy(API gravity 10 - 22)
Notes: API = American Petroleum Institute. Denser oils have lower gravity values
Denser oils are made of longer-chain molecules

Oil explorationOil explorationDone by geologists
◦Look for evidence of source and trap rock Interpret maps Test drilling
Look for oil bearing strata Presence of certain micro-algae
◦Additional methods Magnetometers / gravity meters Seismic testing “Sniffers” detect hydrocarbons in the air

History of PetroleumHistory of PetroleumOil well known in ancient world
◦Ancient Babylonians, Greeks, Chinese used for paving streets, lighting, medicines, producing salt
By middle ages, kerosene isolated, used for lighting
In US, oil obtained in PA and NY from shallow pools.

Petroleum in 19Petroleum in 19thth Century CenturyProduction increased greatly in US and
Europe due to improved drilling technology◦Drake well in Titusville in 1859◦Other wells in California, Europe, and
Canada in next few years◦Development of internal combustion engine
in late 1800s increased demand.

Petroleum in 20Petroleum in 20thth Century Century Demand and production
increased throughout the first half of century.◦ Cars, Trains, Planes, Home
heating◦ Rise of plastics
Drilling increasingly shifted offshore
Middle-Eastern countries became large-scale producers by 1950s.
OPEC formed in 1960. Oil embargos in 1973 / 79 had
worldwide economic impact. Environmental issues noted by
1980s. Focus on finding alternatives.
