Type

Notes

air

 

This is generally an injected fluid.

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 non-associated gas well gas, normally are recovered from lease separators or field facilities by mechanical separation.

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.

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.

gas-water

 

The well facility is classified as producing both gas and water. USe this classification when the produced stream flow is a mixture of gas and water. When a facility produces gas and water in separate streams, classify it twice, as gas and as water.

non HC gas

 

The well produces or injects non-hydrocarbon gases. Typical other gases would be helium and carbon dioxide.

non HC gas -- CO2

 

Carbon dioxide gas.

oil

 

The liquid hydrocarbon generally referred to as crude oil.

oil-gas

 

The well facility is classified as producing both gas and oil. Use this classification when the produced stream flow is a mixture of oil and gas. When a facility produces oil and gas in separate streams, classify it twice, as oil and as gas.

oil-water

 

The well facility is classified as producing both oil and water. Use this classification when the produced stream flow is a mixture of oil and water. When a facility produces oil and water in separate streams, classify it twice, as oil and as water.

steam

 

The gaseous state of water. This is generally an

injected fluid, but it is possible that some hydrothermal wells

produce steam.

water

 

The well is classified as a water well without

distinguishing between brine or fresh water.

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.

unknown

 

The value is not known. Avoid using this value. All reasonable attempts should be made to determine the appropriate value. Use of this value may result in rejection in some situations.
