PROSPECTING AND EXPLORATION

There are three major exploration methods now: surface feature mapping, seismograph observations and Earth gravity surveys.

Surface method. A seepage of crude oil sometimes appears as a tarlike deposite in a low area. It can be seen as a thin skim of oil on small creeks that pass through the seepage area. These methods are not applicable to the large majority of underground reservoirs that do not have leakage to the surface.

Seismographic methods. Seismic methods involve the transmission and echo-producing properties of rock in a manner similar to underwater sonar methods. Possible locations for petroleum accumulations may then be located for drilling.

Gravity meter surveys. The gravity meter has become a primary exploration tool. Gravity surveys are carried out from the air. The gravity meter survey is faster and less expensive than the seismic method. It is generally used as a preliminary survey tool to locate areas in which seismic work may profitably be concentrated.

PETROLEUM REFINING

Crude oil is unsuitable for direct use. It is converted into such useful products through the refining process. Petroleum refining began in the United States and Russia in the second half of the 19th century.

After World War I a major improvement in refining came with development of the cracking process.

During the 1930s and World War II, sophisticated refining processes involving the use of catalysts led to further improvements in the quality of fuels and increased their supply.

The 1950s and '60s brought a large-scale demand for jet fuel and for high-quality lubricating oils.

The various hydrocarbon compounds that are mixed together in crude oil have different boiling points.

Four main types of hydrocarbons are present in crude oil: normal paraffins, isoparaffins, cycloparaffins (also called naphthenes), and aromatics.
