Abstract:
1. A method of associating time stamped measurement data with a corresponding wellbore depth comprising: positioning an interface in a wellbore, wherein the interface having a master clock is in communication with a plurality of tools, each said tool has a clock and can independently measure, record and transmit data acquired from and/or through the wellbore; continuously transmitting depth data to a terminal comprising a surface clock wherein the surface clock and master clock are synchronized and the terminal sends a current time to the interface or the tools, the clock of each said tool is synchronized to the current time; time stamping the depth data; obtaining measurement data from at least one tool of the plurality of tools; time stamping the measurement data with the current time wherein time stamped measurement data is generated; and transmitting time stamped measurement data to the terminal wherein the terminal correlates the time stamped measurement data with time stamped depth data to generate depth tagged data and the terminal generates a depth log.
