Glossary

The terms referenced in this glossary reflect their meaning as used by MEG Energy and the oil sands industry.

API gravity
Expressed in degrees, American Petroleum Institute gravity is a measure of the relative density of a petroleum liquid. MEG's blended product, Access Western Blend, has an API gravity of approximately 22 degrees.
AWB
Access Western Blend, or AWB, is the blend of bitumen and diluent MEG ships from its producing areas to the Edmonton-area refining and transportation hub.
bbls
Barrels of petroleum product. Also often expressed as bpd for barrels per day.
bitumen
A naturally-occurring, very heavy oil consisting mainly of pentanes and heavier hydrocarbons. Crude bitumen may contain sulphur and other non-hydrocarbon compounds.
Christina Lake Assets/Facility/Project
MEG's lease holdings (approximately 200 square kilometres), physical assets and associated development plans approximately 100 kilometres south of Fort McMurray.
cogeneration
A process that uses heat generated from clean burning natural gas to produce both steam and electricity. MEG uses the steam and a portion of the electricity generated in its operations, and sells the excess power as a lower-carbon energy source to the Alberta grid.
contingent resources
The estimated volume of bitumen in a given area that may or may not be commercially viable to produce for a variety of reasons. The contingent resource classification involves greater risks and uncertainties than the "reserves" classification. See Oil and Gas Information section of our Legal Notice.
core hole
A cylindrical sample drilled from subsurface areas to analyze the characteristics of a resource base.
dilbit
A blend of diluent and bitumen.
diluent
Lighter viscosity petroleum products that are used to dilute bitumen for transportation in pipelines
downstream
The segment of the petroleum industry involved in crude oil refining and marketing of refined products.
Growth Properties
MEG's currently non-producing oil sands leases in the Thornbury, May River, West Jackfish, Kirby and Portage areas of Alberta.
in situ
From the Latin, 'in place', a process for recovering bitumen from oil sands by means other than surface mining, such as steam-assisted gravity drainage (SAGD).
midstream
The segment of the petroleum industry involved in transportation, blending and storage of crude oil.
MW
MW - Megawatt, a unit of electrical power generation capability.
oil sands
Deposits containing a mixture of bitumen, sand and water.
ramp-up
The period after physical completion of construction of a project during which steam injection begins and bitumen production begins to increase toward design capacity.
reclamation
The return of disturbed surface land forms and vegetation to a state similar to that before industrial activity took place.
reserves
Estimated recoverable portion of a resource. Proved reserves are reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves. Probable reserves are less certain to be recovered than proved reserves. See Oil and Gas Information section of our Legal Notice.
SAGD
Steam-assisted gravity drainage, an in situ process used to recover bitumen from oil sands.
seismic data
Interpretive data that allows a view of subsurface strata beneath a prospective area. May be presented in two-dimensional or the more detailed and accurate three-dimensional forms.
Surmont Project
MEG's currently non-producing lease holdings (approximately 80 square kilometres) and associated development plans approximately 60 kilometres south of Fort McMurray.
upstream
The segment of the petroleum industry involved in exploration, development and production of petroleum resources.
