Associated Petroleum Gas (APG), also known as flare gas or associated gas, is a form of natural gas which is commonly found associated with deposits of petroleum.
Historically, this type of gas was released as a waste product from the petroleum extraction industry. Due to the remote location of many oil fields, either at sea or on land, this gas was simply burnt off in gas flares.
The flaring of APG is controversial as it is a pollutant, a source of global warming and is a waste of a valuable fuel source. APG is flared in many countries where there are significant power shortages. Producers are foregoing valuable revenue streams by flaring and venting gas associated with gas and oil production. Current estimates suggest that over 150 billion cubic meters of natural gas are flared or vented annually, an amount worth approximately 30.6 billion dollars.
A portion of this gas contains high value hydrocarbons such as ethane, propane, butane, pentanes and others, so called natural gas liquids or NGLs. After processing, it can be utilized in a number of cost saving or revenue creation ways such as: natural gas distribution networks, on-site electricity generation with engines or turbines, re-injected for enhanced oil recovery, or used as feedstock for the petrochemical industry.
Gas can also be used to operate drill rigs at considerably lower costs compared to diesel.
