Glossary

Bitumen

A tar-like mixture of petroleum hydrocarbons which has a naturally occurring viscous mixture of hydrocarbons, which contains sulphur compounds and will not flow to a well in its natural state.

Bitumen is also known as extra-heavy oil has a sticky quality which at room temperature resembles cold molasses.

Diluent

A light petroleum liquid also used to dilute produced bitumen and heavy oil and provide assistance in transporting product to market.

Downstream

Refining and marketing sector of the petroleum industry.

Heavy Oil

Denser, viscous oil, with a high proportion of bitumen.

Oilsands

Natural occurring mixture of bitumen, water, sand and clay.

Pig

A cylindrical device inserted into a pipeline to inspect or clean the pipeline of water, rust or other foreign material. A “smart-pig” may also be used to detect corrosion cracks or weakness in the welding.

Right-of-way

A strip of land of which has been acquired for the construction and operation of a pipeline or facility. Land may be owned outright or easement taken for a specific purpose.

Setback

The distance required to separate a project, such as a well or pipeline, from another activity ie: settlement, water well or water course.

Stakeholder

A person with an interest in an issue. A stakeholder may include nearby resident, business, interest group, government agency and industry.

Steam-assisted gravity drainage (SAGD)

A recovery technique to extract heavy oil or bitumen and requires the drilling of two horizontal wells; one for steam injection and the other for production.

Supervisory Control and Data Acquisition (SCADA)

SCADA assists with monitoring the movement of product through transmission lines. The control system is made up of computers and sensors situated at pump and compressor stations along the pipeline route. Communications between systems allow the pipeline operator to completely operate the system from one central location.

Measurements

Bbl (Barrel)

A traditional measurement of oil. One barrel is equivalent to 158.9 litres or 42 U.S. gallons. Quick fact: A standard bathtub holds about one barrel of oil.

Bod

Barrels of oil per day

M (Metre)

Equivalent to 3.28 feet.

m³ (Cubic Metre)

A standard unit of volume measurement and is equivalent to 6.29 barrels. Quick fact: One cubic metre of oil would fill 1,000 one-litre milk cartons.
