Ligroine (Ligroin): A saturated petroleum naphtha boiling in the
range of 20 to 135°C (68 to 275°F) and suitable for general use as
a solvent; also called benzine or petroleum ether.
Liquefied petroleum gas: Propane, butane, or mixtures thereof,
gaseous at atmospheric temperature and pressure, held in the
liquid state by pressure to facilitate storage, transport, and
handling.
Live cull: A classification that includes live cull trees; when associated with volume, it is the net volume in live cull trees that are
5.0 inches in diameter and larger.
Live steam: Steam coming directly from a boiler before being
utilized for power or heat.
Logging residues: The unused portions of growing-stock and
non-growing-stock trees cut or killed logging and left in the

Lube: See Lubricating oil.
Lube cut: A fraction of crude oil of suitable boiling range and
viscosity to yield lubricating oil when completely refined; also
referred to as lube oil distillates or lube stock.
Lubricating oil: A fluid lubricant used to reduce friction between
bearing surfaces.
M
M85: An alcohol fuel mixture containing 85 percent methanol and
15 percent gasoline by volume. Methanol is typically made
from natural gas, but can also be derived from the fermentation
of biomass.
Marsh: An area of spongy waterlogged ground with large numbers of surface water pools. Marshes usually result from: (1) an
impermeable underlying bedrock; (2) surface deposits of glacial
boulder clay; (3) a basin-like topography from which natural
drainage is poor; (4) very heavy rainfall in conjunction with
a correspondingly low evaporation rate; (5) low-lying land,
particularly at estuarine sites at or below sea level.
Mbbls: 1,000 barrels of oil.
Mcf: 1,000 cubic feet of natural gas.
Mcfe: 1,000 cubic feet equivalent, determined using the ratio of six
Mcf of natural gas to one barrel of crude oil.
Megawatt: (MW) A measure of electrical power equal to one
million watts (1,000 kW).
