Abstract

A master data acquisitions system is provided. A trigger emits a sync signal to be sensed by each of a plurality of data acquisition systems. A controller is communicatively coupled with each of the plurality of data acquisition systems. The controller receives data from each of the data acquisition systems. The data for each of the plurality of data acquisition systems include the sensed sync signal. The controller synchronizes the data from each of the plurality of data acquisition systems by aligning the sensed sync signal for each of the plurality of data acquisition systems.

First claim

What is claimed is:

1. A master data acquisition system (DAQ) comprising:
a trigger which emits a sync signal to be sensed by each of a plurality of DAQs that are associated with a manmade fluidic channel; and
a controller communicatively coupled with each of the plurality of DAQs associated with the manmade fluidic channel, wherein:
the controller receives data from each of the plurality of DAQs, the data for each of the plurality of DAQs including information associated with the sensed sync signal, and
the controller synchronizes the data from each of the plurality of DAQs by aligning the information associated with the sensed sync signal for each of the plurality of DAQs.

2. The master DAQ of claim 1 , wherein the sync signal is an acoustic signal.

3. The master DAQ of claim 1 , wherein the acoustic signal includes at least one of the following: an acoustic pulse, an ultrasound signal, or a pressure wave.

4. The master DAQ of claim 1 , wherein each of the plurality of DAQs is connected to a transmission line, wherein the trigger emits the sync signal within the transmission line.

5. The master DAQ of claim 4 , wherein the transmission line is substantially homogenous, wherein the transmission line includes at least one of the following: fluid, rock, metal, or concrete.

6. The master DAQ of claim 1 , wherein the synchronization of the data by the controller includes shifting the data from each of the plurality of DAQs, trimming the data, and combining the data.

7. The master DAQ of claim 1 , wherein each of the plurality of DAQs includes one or more sensors communicatively coupled with one another.

8. The master DAQ of claim 1 , wherein the trigger emits the sync signal periodically.

9. A system comprising:
a plurality of data acquisition systems (DAQs) that are associated with a manmade fluidic channel, each of the plurality of DAQs associated with the manmade fluidic channel including a signal sensor; and
a master DAQ including:
a trigger which emits a sync signal sensed by the signal sensor of each of the plurality of DAQs; and
a controller communicatively coupled with each of the plurality of DAQs, wherein:
the controller receives data from each of the plurality of DAQs, the data for each of the plurality of DAQs include information associated with the sensed sync signal, and
the controller synchronizes the data from each of the plurality of DAQs by aligning the information associated with the sensed sync signal for each of the plurality of DAQs.

10. The system of claim 9 , wherein the sync signal is an acoustic signal.

11. The system of claim 9 , wherein the acoustic signal includes at least one of the following: an acoustic pulse, an ultrasound signal, or a pressure wave.

12. The system of claim 9 , wherein each of the plurality of DAQs is connected to a transmission line, wherein the trigger emits the sync signal within the transmission line.

13. The system of claim 12 , wherein the transmission line is substantially homogenous, wherein the transmission line includes at least one of the following: fluid, rock, metal, or concrete.

14. The system of claim 9 , wherein the synchronization of the data by the controller includes shifting the data from each of the plurality of DAQs, trimming the data, and combining the data.

15. The system of claim 9 , wherein each of the plurality of DAQs includes one or more sensors communicatively coupled with one another.

16. The system of claim 15 , wherein the one or more sensors measure parameters of at least one of the following: a formation, a wellbore, a conduit disposed in a wellbore or a pipeline.

17. The system of claim 9 , wherein the trigger emits the sync signal periodically.

18. A method comprising:
emitting, by a trigger, a sync signal to a plurality of data acquisition systems (DAQs) that are associated with a manmade fluidic channel;
receiving, by a controller, data from each of the plurality of DAQs associated with the manmade fluidic channel, the data for each of the plurality of DAQs including information associated with the sensed sync signal; and
synchronizing, by the controller, the data from each of the plurality of DAQs by aligning the information associated with the sensed sync signal for each of the plurality of DAQs.

19. The method of claim 18 , wherein the synchronizing of the data includes:
shifting the data from each of the plurality of DAQs;
trimming the data; and
combining the data.

20. The method of claim 18 , wherein each of the plurality of DAQs includes one or more sensors communicatively coupled with one another, wherein the one or more sensors measure parameters of at least one of the following: a formation, a wellbore, a conduit disposed in a wellbore, or a pipeline.
