Fluids Hydrocarbons + trace amount of otherelements

Hundreds to thousands of chemicalcompoundsMcCain, 1990


11/24

Chemical Composition of Petroleum

Fluids Hydrocarbons -- organic compounds Vary in numbers of carbon, with generalformula of CnHy

Saturated (single bonds), unsaturated

(multiple bonds)

Open chain, ring or cyclic

McCain, 1990


18/24

Characterization of Petroleum Fluids

Chemical composition analysis Physical Propertiescolor, odor, refractive index, density,

boiling point, melting point, viscosity

McCain, 1990


19/24


Specific gravity (): the ratio of density of the

liquid to the density of water, both at specifiedT and P.

Typical values: 0.75 to 1.01

API gravity (American Petroleum Institute):

McCain, 1990

141.5

API 131.5


20/24


21/24


The larger number of carbon, the higher boilingand melting points, and the higher specific

gravity. McCain, 1990


22/24

Distribution of Fluids in Reservoirs

Oil reservoir

Associated oil-gas reservoir

Gas reservoir

(Fig. 1.3, amyx)

Driving forces?

Gravitation Capillary

Oil zoneGas-oil transitional zone

water zone


23/24

Petroleum Reservoirs

a body of porous and permeable rock containing

oil and gas through which fluids may move towardrecovery openings under pressures existing or thatmay be applied.

Sedimentary rocks
