Well Fluid Type wellFluidType extWellFluidType refinedWellFluidType refinedExtWellFluidType POSC 1.0 oil The liquid hydrocarbon, generally referred to as crude oil. gas The well is classified as a gas well, producing or injecting a hydrocarbon gas. The gas is generally methane, but may have a mixture of other gases also. non HC gas The well produces or injects non hydrocarbon gases. Typical other gases would be helium and carbon dioxide. CO2 Carbon Dioxide gas. non HC gas water The well is classified as a water well without distinguishing between brine or fresh water. brine The well facility is classified as producing or injecting salt water. water fresh water The well facility is classified as producing fresh water that is capable of use for drinking or crop irrigation. water oil-gas The well facility is classified as producing both gas and oil. This classification is to be used when the produced stream flow is a mixture of oil and gas. When a facility produces oil and gas in separate streams, it should be classified twice as oil and as gas. oil-water The well facility is classified as producing both oil and water. This classification is to be used when the produced stream flow is a mixture of oil and water. When a facility produces oil and water in separate streams, it should be classified twice as oil and as water. gas-water The well facility is classified as producing both gas and water. This classification is to be used when the produced stream flow is a mixture of gas and water. When a facility produces gas and water in separate streams, it should be classified twice as gas and as water. 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 dissolved in the gaseous state under reservoir conditions but separates as a 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. steam The gaseous state of water. This is generally an injected fluid, but it is possible that some hydrothermal wells produce steam. air This is generally an injected fluid. dry The well facility is classified as a dry well. It has not been, nor will it be used to produce or inject any fluids. unknown The fluid type is unknown. If a well or wellbore is classified by its fluid type, it is not known what the classification is.
