A log is the recording of one physical property of the formation crossed through by a borehole or of the geometric characteristics of the hole or casing or the flow behavior of a well as a function of depth. Wireline logging is performed with a sonde or probe lowered into the borehole or well, usually after the drillstring has been withdrawn.  4, fiche 1, Anglais, - wireline%20log

Measurements include electrical properties ... sonic properties, active and passive nuclear measurements, dimensional measurements of the wellbore, formation fluid sampling, formation pressure measurement, wireline-conveyed sidewall coring tools, and others. In wireline measurements, the logging tool (or sonde) is lowered into the open wellbore on a multiple conductor, contra-helically armored wireline. Once lowered to the bottom of the interval of interest, the measurements are taken on the way out of the wellbore. This is done in an attempt to maintain tension on the cable (which stretches) as constant as possible for depth correlation purposes ... Most wireline measurements are recorded continuously even though the sonde is moving.  3, fiche 1, Anglais, - wireline%20log
