Delta-T Shear, Receiver Array - Lower Dipole (DT1R) |
This is an abbreviation for a well log used in the oil and gas industry. The acronym DT1R is a unique identifier to recognize this particular log and can be encountered in your log evaluation software or your corporate datastores. Delta-T Shear, Receiver Array - Lower Dipole is the offical name for this log. Usage of this log is not high and encountering it is a rare occasion. This log can be used to evaluate the acoustic slowness of a shear wave (Vs); reciprocal of Shear Velocity; a shear wave is a type of seismic wave in which the particle motion is perpendicular to the direction of propagation; also called S-wave or secondary wave. Furthermore, this can be explained by looking at 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:
