Delta-T Compressional from Receiver Array (DTRA) |
This is the name of a log measured along a well bore (a well-log). You might have encountered this acronym DTRA in your log evaluation software or any (ASCII) log files provided by the logging company. Delta-T Compressional from Receiver Array is the full name for this log. The business value of this log is often deamed high. This log helps to evaluate the time it takes for a compressional wave to traverse a fixed distance; reciprocal of Compressional Velocity. At a more general level these values are measures of the interval transit time (The travel time of a wave over a unit distance, hence the reciprocal of wave velocity).This log usually has the unit 'Acoustic Slowness'. This is the time interval per unit length, Delta-T, necessary to attenuate a traveling acoustic wave. Applies to all types of Delta-T: Compressional, Shear and Stoneley. 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:
