  • MEASUREMENT DEVICES WITH MEMORY TAGS AND METHODS THEREOF
    Publication number: 20110191028
    Abstract: A downhole measurement device includes one or more sensors configured to measure a parameter in a well; a plurality of memory tags for storing measurement data from the one or more sensors; and an ejection module configured to release one of the plurality of memory tags upon a predetermined condition. A method for monitoring a well includes deploying of a measurement device having one or more sensors and a plurality of memory tags into a wellbore; obtaining measurement data of the parameter using the one or more sensors; writing the measurement data to one of the plurality of memory tags; releasing the memory tag having the measurement data; allowing the memory tag having the measurement data to be carried by a flow in the wellbore uphole; reading the measurement data from the memory tag having the measurement data at a location remote from the downhole measurement device.
