A gas composed entirely of hydrocarbons.

Hydrocarbons– substance made of hydrogen and carbon (among other elements)

Grade through three states of matter: gases, liquids and solids. Petroleum exploration largely concerned with the fluids (gases and liquids).

Several specific forms of hydrocarbons-

  • Dry gas– contains largely methane, specifically contains less than 0.1 gal/1000ft3 of condensible (at surface T and P) material.
  • Wet gas– contains ethane propane, butane. Up to the molecular weight where the fluids are always condensed to liquids
  • Condensates– Hydrocarbon with a molecular weight such that they are gas in the subsurface where temperatures are high, but condences to liquid when reach cooler, surface temperatures.
  • Liquid hydrocarbons– commonly known as oil, or crude oil, to distinguish it from refined hydrocarbon products.
  • Plastic hydrocarbons– asphalt
  • Solid hydrocarbons– coal and kerogen- (kerogen strictly defined is disseminated organic matter in sediments that is insoluble in normal petroleum solvents.
  • Gas hydrates- Solids composed of water molecules surrounding gas molecules, usually methane, but also H2S, CO2, and other less common gases.
