Zusammenfassung:	A launching system (100) for an autonomous unit RAU carrying a logging tool for oil and gas well logging is described, said system comprising a main body 15 provided with first and second control valves 13,14 respectively and draining valve 17, sensors 16 and End Cap 18 electrically connected to a control room for transmission of the data collected by the logging tool carried by the RAU, said End Cap 18 collecting data and charging the electrical battery of the autonomous unit RAU carrying said logging tool to be launched by said main body 15 and performing a schedule of logging tasks in the well; and connection 19 for wellhead. The method for installation and uninstallation of the autonomous unit in the said system as well as a rescue system for the said autonomous unit in case of hindered motion of the RAU for any reason are also described.
