Coherent Compressional Energy (CHE) |
This is the name of a log measured along a well bore (a well-log). You could have found the code CHE in your log evaluation software or your corporate datastores. Coherent Compressional Energy is the full name for this log. This log is not often acquired after (or during) drilling a well. This log displays readings of the energy of an acoustic wave, calculated as the sum of the squares of the amplitudes of the elements in a wavelet, sometimes multiplied by a proportionality constant.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 for this log is produced by a tool that uses a acoustic logging technique and can be used to investigate the energy. Similar logs are listed below:
