Beschreibung
Zusammenfassung:	A well probe including two offset shoes fixed outside of a tubular column and an intermediate shoe provided with a central passage having a cross section larger than a cross section of the column. The intermediate shoe is connected to a lower offset shoe by a mobile hasp. A mobile harness is adapted to be moved into and out of a lateral cavity of the intermediate shoe for enabling coupling and uncoupling of the intermediate shoe with a wall of the well. The mobile harness includes a casing for accommodating sensors and a hydraulic triggering arrangement, with the sensors and the hydraulic triggering arrangement being connected to a surface installation by cables and an electronic cartridge.
