GLOSSARY OF OIL AND NATURAL GAS TERMS
Analogous
Reservoir: Analogous reservoirs, as used in resource
assessments, have similar rock and fluid properties, reservoir
conditions (depth, temperature and pressure) and drive mechanisms,
but are typically at a more advanced stage of development than the
reservoir of interest and thus may provide concepts to assist in
the interpretation of more limited data and estimation of recovery.
When used to support proved reserves, analogous reservoir refers to
a reservoir that shares all of the following characteristics with
the reservoir of interest: (i) the same geological formation (but
not necessarily in pressure communication with the reservoir of
interest); (ii) the same environment of deposition; (iii) similar
geologic structure; and (iv) the same drive mechanism.
Bbl: One
stock tank barrel, or 42 U.S. gallons liquid volume, used in
reference to oil or other liquid hydrocarbons.
Bbl/d: One
Bbl per day.
Bcfe: One
billion cubic feet of natural gas equivalent.
Boe: One
barrel of oil equivalent, calculated by converting natural gas to
oil equivalent barrels at a ratio of six Mcf of natural gas to one
Bbl of oil.
BOEM: U.S.
Bureau of Ocean Energy Management.
Btu: One
British thermal unit, the quantity of heat required to raise the
temperature of a one-pound mass of water by one degree
Fahrenheit.
CO2:
Carbon dioxide.
Development
Project: A development project is the means by which
petroleum resources are brought to the status of economically
producible. As examples, the development of a single reservoir or
field, an incremental development in a producing field or the
integrated development of a group of several fields and associated
facilities with a common ownership may constitute a development
project.
Dry Hole or Dry
Well: A well found to be incapable of producing hydrocarbons
in sufficient quantities such that proceeds from the sale of such
production would exceed production expenses and taxes.
Economically
Producible: The term economically producible, as it relates
to a resource, means a resource which generates revenue that
exceeds, or is reasonably expected to exceed, the costs of the
operation. For this determination, the value of the products that
generate revenue are determined at the terminal point of oil and
natural gas producing activities.
Exploitation: A
development or other project which may target proven or unproven
reserves (such as probable or possible reserves), but which
generally has a lower risk than that associated with exploration
projects.
Field: An
area consisting of a single reservoir or multiple reservoirs, all
grouped on or related to the same individual geological structural
feature and/or stratigraphic condition. The field name refers to
the surface area, although it may refer to both the surface and the
underground productive formations.
Gross Acres or
Gross Wells: The total acres or wells, as the case may be,
in which we have a working interest.
ICE:
Inter-Continental Exchange.
MBbl: One
thousand Bbls.
MBbls/d:
One thousand Bbls per day.
MBoe: One
thousand barrels of oil equivalent.
