This is the name of a log measured along a well bore (a well-log). The acronym
T2PL is a unique identifier to recognize this particular log and can be encountered in your log evaluation software or your corporate datastores.
Dielectric Propagation Time is the full name for this log. The usage of this log is well established. This log helps to evaluate the time per unit length required for an electromagnetic wave to propagate over some interval in some medium like air, water, drilling fluid, etc.. 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
'Time'. This is the 1) The measured or measurable period during which an action, process, or condition exists or continues. 2) The point or period when something occurs. 3) A fixed moment or hour for something to happen, begin, or end. 4) A historical period.
Data for this log is produced by a tool that uses a electromagnetic logging technique and can be used to investigate the time interval of the formation. Similar logs are listed below:
