Description
|
AUXILIARY
|
Data not normally included has been pro-
vided at the specific request of the con-
sumer, possibly at some additional cost.
|
| AVERAGED |
The data is the average of two or more
other sources.
|
| CALIBRATED |
A calibration process has been applied to
the data.
|
| CHANGED-INDEX |
The data has been resampled along an
index that is different from its original sam-
pling index. For example, data that was
originally sampled according to time is res-
ampled according to depth, or data origi-
nally sampled according to measured depth
is resampled according to vertical depth.
|
| COMPUTED |
The data is the output of a transform, e.g.,
function former, based on input data from a
single tool.
|
| DEAD-TIME-CORRECTED |
The data has been corrected for dead time.
|
| DEPTH-MATCHED |
The data has been aligned along its depth
index against a reference data source.
|
| DERIVED |
The data is an output of empirical equa-
tions or is the solution of log response
equations based on input data from more
than one tool.
|
| ENVIRONMENTALLY-CORRECTED |
All known borehole corrections have been
applied to the data.
|
| FILTERED |
A filtering process has been applied to the
data.
|
| HOLE-SIZE-CORRECTED |
The data has been corrected for hole size
effect based on the value of a hole size
input.
|
| INCLINOMETRY-CORRECTED |
The data has been corrected to standard
directional references (vertical axis and
North axis).
|
| LITHOLOGY-CORRECTED |
The data has been corrected or computed
based on the value of a matrix lithology
parameter.
|
| LOCAL-COMPUTATION |
The data is the result of locally-defined
computational expressions. Such data is
normally experimental.
|
| LOCALLY-DEFINED |
The object's name has been created by the
operator. This name might not be dictio-
nary-controlled and may have no semantic
association with the object's data.
|
| MODELLED |
The data is the output of a theoretical
model and is not derived from any mea-
sured quantity.
|
| MUD-CORRECTED |
The data has been corrected for effects of
mud.
|
| MUDCAKE-CORRECTED |
The data has been corrected for mudcake
effect.
|
| NORMALIZED |
The data has been corrected so that its
range corresponds to a prescribed norm.
|
| OVER-SAMPLED |
Interpolated data samples have been added
to the original data to align this data with
other data.
|
| PATCHED |
The original data values have been replaced
at specific levels. This is normally done to
remove spurious values (e.g.,spikes).
|
| PRESSURE-CORRECTED |
The data has been corrected for hydrostatic
pressure (mud weight).
|
| PROPRIETARY |
Data is proprietary to the producer and is
not warranted for use by the consumer.
|
| RE-SAMPLED |
The data has been resampled along its orig-
inal index. For example, the original index
values may be wrong. Using a curve-fit, it
may be possible to compute new data val-
ues that fit the original signal more accu-
rately along the original index.
|
| SALINITY-CORRECTED |
The data has been corrected for salinity
effect.
|
| SAMPLED-DOWNWARD |
The original sampling direction is down-
ward.
|
| SAMPLED-UPWARD |
The original sampling direction is upward.
|
| SPEED-CORRECTED |
The data has been corrected for variations
of the downhole tool speed.
|
| SPLICED |
The data has been obtained by concatenat-
ing two or more other data sources.
|
| SQUARED |
The data is the result of a squaring process,
i.e., a process that converts a smooth func-
tion into a step function.
|
| STACKED |
The data is the sum of two or more other
data sources.
|
| STANDARD-DEVIATION |
The data represents the estimated devia-
tion, due to environmental factors or inco-
herence of the computational model, of
another data source.
|
| STANDOFF-CORRECTED |
The data has been corrected for standoff
effect.
|
| TEMPERATURE-CORRECTED |
The data has been corrected for tempera-
ture effect based on the value of a tempera-
ture source.
|
| UNDER-SAMPLED |
Some of the original data samples have
been discarded to reduce the amount of
data or to align this data with other data.
