GLOSSARY
are estimates for proved undeveloped reserves generally attributed to any acreage for which an application of fluid injection
or other improved recovery technique is contemplated, unless
such techniques have been proved effective by actual tests in
the area and in the same reservoir.
Pulpwood: Round wood, whole-tree chips, or wood residues that
are used for the production of wood pulp.
Pyrolysis: The thermal decomposition of biomass at high temperatures (greater than 400°F, or 200°C) in the absence of air; the
end product of pyrolysis is a mixture of solids (char), liquids
(oxygenated oils), and gases (methane, carbon monoxide, and
carbon dioxide) with proportions determined by operating
temperature, pressure, oxygen content, and other conditions.
Q
Quad: One quadrillion Btu (10
15 Btu) = 1.055 exajoules (EJ), or
approximately 172 million barrels of oil equivalent.
Quadrillion: 1 x 10
15
.
Quench: the sudden cooling of hot material discharging from a
thermal reactor.
R
Raw materials: Minerals extracted from the earth prior to any refining or treating.
Recompletion: The completion for production of an existing well
bore in another formation from that in which the well has been
previously completed.
Recovery boiler: A pulp mill boiler in which lignin and spent cooking liquor (black liquor) is burned to generate steam.
Refining: The processes by which petroleum is distilled and/or
converted by application of a physical and chemical processes
to form a variety of products are generated.
Reformulated gasoline (RFG): Gasoline designed to mitigate smog
production and to improve air quality by limiting the emission
levels of certain chemical compounds such as benzene and
other aromatic derivatives; often contains oxygenates (q.v.).
Refractory lining: A lining, usually of ceramic, capable of resisting
and maintaining high temperatures.
Refuse-derived fuel (RDF): Fuel prepared from municipal solid
waste; non-combustible materials such as rocks, glass, and
