Delta-T Long Spacing Near (DTLN) |
This is an acronym for a well log used in the oil and gas industry. You might have encountered this acronym DTLN in your log evaluation software or any (ASCII) log files provided by the logging company. The official name for this log is 'Delta-T Long Spacing Near'. This log is very common in the industry. The values of this log represent the time it takes for a compressional wave to traverse a fixed distance; reciprocal of Compressional Velocity. In general this is a measurement 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:
