Well / Formula Log
www.alt.lu
Description:
The Well Log handles single point data sampled at a constant rate. It is used to
display any kind of equally sampled geophysical data as curve (e.g. Gamma Ray,
Density, Resistivity, Porosity, Transit Time). Well Log data is generally imported
from LAS, LIS, DLIS or ASCII files (*.txt, *.csv) but can also be generated
interactively (e.g. grain size curve in core description).
The sampling rate of a Well Log is automatically set when data is imported from a
file. It is recalculated from the number of data points and the distance between the
top and bottom depth. If a Well Log is created from scratch the user will be asked to
provide the sampling interval.
An option to re-sample a selected Well Log can be found in the Process >
Common menu.
Formula Logs are calculated curves using one or more Well Logs as data source.
They are dynamically linked to Well Logs and the log type specific settings are the
same.
