Oil and Gas industry's glossary

A light aromatic hydrocarbon, which occurs naturally as a part of oil and natural gas activity. It’s considered to be a non-threshold carcinogen and is an occupational and public health concern.

THIS WORD is a shift of greenhouse gas emissions from one part of the globe to another, so from one country to another. This occurs when companies choose to move oil and natural gas production to a region with lower costs, but often fewer or no environmental regulations. As a result, there is no reduction in net global greenhouse gas emissions.

A standard THIS WORD of oil holds about 42 U.S. gallons or roughly 159 litres. THIS WORD was adopted in the early days of U.S. oil and gas production as a way to transport oil. Today, we continue to use it to measure transport volumes and pricing around the world.

The American Petroleum Institute gravity, or THIS WORD, is a measure of how heavy or light a petroleum liquid is compared to water: if its THIS WORD is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. THIS WORD can be used to calculate how many barrels of crude oil can be produced per metric ton. Given that the weight of an oil plays an integral role in establishing its market value, ___ is an important measure.

The process of changing a once active well (one that will no longer produce oil or natural gas), to a state where it can be left indefinitely. All equipment that was used to produce oil and gas is removed and work is completed on the well to ensure that it will not cause harm to any environmental or human surroundings.

A type of pump used to transfer fluids and the most common pump used in the oil and gas industry. THIS WORD pumps move fluid by rotation and draw fluid into the suction end of the pump and then, through THIS WORD force, forces it out of the discharge end.

Natural gas generated and trapped in coal seams.

Production of oil or gas to date.

Heavy, viscous oil that must be processed extensively to convert it into a crude oil before it can be used by refineries to produce gasoline and other petroleum products.

A large, onsite containment system to safely store water used for or produced from oil and gas production.
