crude oil | A mixture of varying proportions of hydrocarbons, natural gas, and entrained sediments and water. Crude oil exists in the liquid phase in natural underground reservoirs and remains a liquid at atmospheric pressure and 60 degrees Fahrenheit. | POSC | epicentre 2.2 | current |
natural gas | Gaseous forms of petroleum consisting of mixtures of hydrocarbon gases and vapors, the more important of which are: methane, ethane, propane, butane, pentane, and hexane. It may exist either in the gaseous phase or in solution with crude oil in reservoirs. | POSC | epicentre 2.2 | current |
condensate | Liquid hydrocarbons produced with natural gas that are separated from the gas by cooling and various other means. Condensate generally has an API gravity of 50 degrees to 120 degrees and is water white, straw, or bluish in color. It is the liquid recovery from a well classified as a gas well. It is generally in the gaseous state under reservoir conditions but becomes liquid either in passing up the hole or at the surface. These hydrocarbons, from associated and nonassociated gas well gas, normally are recovered from lease separators or field facilities by mechanical separation. | POSC | epicentre 2.2 | current |
formation water | Water that fills a portion of rock pore space. Water that is inherent to the rock. | POSC | epicentre 2.2 | current |
