Log ASCII Standard
A single LAS file can only contain data for one wellbore, but it can contain any number of curves for that well. Common curves found in a LAS file may include gamma ray logging, sonic logging, or resistivity logging.
Restrictions of the LAS format mean that all the data must be saved in the same sampling interval. This usually is not an issue with most log curves.
