A salvaged diamond or used diamonds in good condition; hence, diamonds
that can be used again by being reset in another tool or bit. Also called
usable diamond; usables; usable stone. Long
a. The act or process of producing a reset bit. See also:reset bit
Long
b. To rerun a casing string into a borehole by placing its bottom end at a
lower point in the hole. Long
a. Characteristic of, pertaining to, or consisting of residuum; remaining
essentially in place after all but the least soluble constituents have
been removed.
b. Standing, as a remnant of a formerly greater mass of rock or area of
land, above a surrounding area that has been generally planed; said of
some rocks, hills, mesas, and groups of such features.
See:grus
A boulder of local origin produced by weathering and standing in locally
derived soil or grus.
Clay material formed in place by the weathering of rock, derived either
from the chemical decay of feldspar and other rock minerals or from the
removal of nonclay-mineral constituents by solution from a clay-bearing
rock (such as an argillaceous limestone); a soil or a product of the
soil-forming processes. CF:primary clay; secondary clay. AGI
An element present in an alloy or other material in small quantities after
some type of treatment, but not added intentionally. ASM, 1
The differences between measured values and the most probable value.
Seelye, 2
a. See:residual magnetic field
b. The field remaining after subtraction of an average or background field
(e.g., gravity, magnetic).
In gravity prospecting, the portion of a gravity effect remaining after
removal of some type of regional variation; usually the relatively small
or local anomaly components of the total or observed gravity field.
AGI
A late-stage magmatic fluid. Syn:rest magma
a. The magnetic field that remains in a part after the magnetizing force
is removed. ASM, 1
b. See:residual field
a. In magnetic prospecting, the portion of a magnetic effect remaining
after removal of some type of regional effect; usually the relatively
small or local anomaly components of the total or observed magnetic field.
AGI
b. The magnetism remaining in a substance after the magnetizing force has
been removed. See also:remanence
The rock-forming minerals that are either stable in the surface
environment or unstable but react so slowly that they are not appreciably
broken down. Hawkes, 1
a. The amount of liquid petroleum remaining in a formation at the end of a
specified production process. AGI
b. Liquid or semi-liquid products obtained as residues from the
distillation of petroleum. They contain the asphaltic hydrocarbons.
Residual oils are also known as asphaltum oil, liquid asphalt, black oil,
petroleum tailings, and residuum. CCD, 2
An accumulation of valuable minerals, formed by the natural removal of
undesired constituents of rocks or conversion of useless to useful
components.
The elements ordinarily present in steel in small quantities without
definite intent on the part of the steel maker. Osborne
The stress that exists in an elastic solid body in the absence of, or in
addition to, stresses caused by an external load. Such residual stress may
be due to: (1) deformation, caused by cold-working, as in drawing or
stamping; (2) change in the specific volume due to thermal expansion, a
phase change, or magnetostriction; (3) by the joining together of
structural parts by force, such as welding. Hammond
a. The waste or final product from a hydrometallurgical plant. Fay
b. S. Afr. The amount of valuable matter remaining in ore after treatment,
in percent or pennyweights per ton. Beerman
c. As applied to proximate analysis of coke, a calculated figure obtained
by subtracting the sum of the percentages of moisture in the analysis
sample, volatile matter, and ash from 100. BS, 1
d. That which remains after a part has been separated or otherwise
treated.
e. See:rock fracture
a. The constituent petrological unit or maceral occurring as
characteristic unresolvable granular and translucent groundmass in
clarain. AGI
b. Same as residuum. Tomkeieff
