Signal to Noise Ratio, Real_time (SNCO_RT)
This is an abbreviation for a well log acquired after or during drilling. The acronym SNCO_RT can be found in any (ASCII) log files provided by the logging company. The official name for this log is 'Signal to Noise Ratio, Real_time'. This log is not used too often in the industry. Use this log to investigate the ratio of signal amplitude to noise amplitude, usually expressed in dB.This log usually has the unit 'Attenuation'. This is the loss in energy or reduction in sensitivity. In seismic work, loss in acoustic energy due to absorption, reflection, etc. which occurs between any two points of travel.
Data from this log can be used to investigate the amplitude.
