Label Peak Coherence, Transmitter Array - Upper Dipole (CHT2) |
This is a log of measurements along a well bore (a well-log). You could have found the code CHT2 in your log evaluation software or your corporate datastores. The official name for this log is 'Label Peak Coherence, Transmitter Array - Upper Dipole'. This log is not often acquired after (or during) drilling a well. The values of this log represent the measure of waveform coherence with respect to slowness and time, computed as a function of coherent energy to total energy; also called "Semblance" Simply said, this is a log that describes the similarity between two or more functions; used with seismic waveforms to distinguish seismic events and to implement automatic picking schemes.This log in unitless. Either the log measurements can not be expressed with a unit (eg. a ratio) or the unit is unknown to us. Data for this log is produced by a tool that uses a acoustic logging technique and can be used to investigate the acoustic slowness of the formation. Similar logs are listed below:
