Abstract
A logging system that may be used in a wellbore formed in an earth. A tubular conduit extends from surface into the wellbore and contains a body of wellbore fluid. A logging tool string may be passed from a position within the conduit to a position outside the conduit at a lower end part thereof, and may be suspended by the conduit in the position outside the conduit. A pressure pulse device is arranged within the conduit in a manner that the pressure pulse device is in data communication with the logging tool. The pressure pulse device is capable of generating pressure pulses in the body of wellbore fluid, which pressure pulses represent data communicated by the logging tool string to the pressure pulse device during logging of earth formation by the logging tool string. The system further includes a control system in fluid communication with the body of wellbore fluid and arranged to receive the pressure pulses.
