Study Notes

Oil & Gas Technologies Course Topics

Part 1 includes fundamental concepts related to the oil and gas industry, focusing on energy production and technologies.
Crude oil and natural gas are considered paramount energy sources due to their high energy density and versatility across various applications.

Energy Subsidies and Contribution

The global economy's primary source of energy subsidies is fossil fuels, which receive significant financial support to remain competitive.
Crude oil and gas contribute approximately 80% to the world's energy supply, highlighting their dominance in global energy markets.

Geological Aspects

Part 4 of the course discusses sedimentary rocks, the primary geological formations where hydrocarbon deposits are found.
The classification of rocks is essential in identifying areas with potential oil and gas reserves.

Chemical Properties

Properties that do not depend on the amount of matter present are known as intensive properties, such as temperature and density.
Alkenes are a type of unsaturated hydrocarbon characterized by at least one double bond between carbon atoms.

Hydrocarbon Types

Unsaturated hydrocarbons, like alkenes, contribute more carbon dioxide per pound compared to saturated hydrocarbons due to higher hydrogen-to-carbon ratios.
Short-chain hydrocarbons, including methane, typically exist in a gaseous state at room temperature.

Crude Oil Classifications

Crude oils are classified based on the predominant hydrocarbon molecules, which include paraffinic, naphthenic, and aromatics.
Paraffinic crude oils primarily consist of saturated hydrocarbons, characterized by high alkane content and low impurities.

Fuel Components

Alkanes, alkenes, and cyclic hydrocarbons represent various components of fuels, each with distinct chemical properties and energy content.
An 'average' crude oil sample is composed mostly of carbon and hydrogen, along with trace amounts of sulfur, nitrogen, and oxygen.

Description

Test your knowledge on the chemistry of hydrocarbon reserves, including the formation, migration, accumulation processes, chemical composition, properties of reservoir hydrocarbons, and the identification of different reservoir rocks.
