Abstract

A system can include a processor; memory accessible by the processor; a network interface; and processor-executable instructions stored in the memory to instruct the system where the instructions include instructions to receive time series data associated with a borehole; compute a similarity metric for at least a portion of the time series data with respect to other time series data for the borehole; and analyze the similarity metric with respect to at least one operation associated with the borehole.

First claim

What is claimed is:

1. A system comprising:
a processor;
memory accessible by the processor;
a network interface; and
processor-executable instructions stored in the memory to instruct the system wherein the instructions comprise instructions to:
receive time series data associated with a borehole;
compute a similarity metric for at least a portion of the time series data with respect to other time series data for the borehole, wherein the similarity metric comprises a statistic, and wherein the statistic comprises one or both of a box plot statistic and a histogram plot statistic; and
analyze the similarity metric with respect to at least one operation associated with the borehole.

2. The system of claim 1 comprising instructions to match at least a portion of the time series data to at least a portion of the other time series data based at least in part on the similarity metric.

3. The system of claim 1 wherein the time series data comprises measured depth with respect to time.

4. The system of claim 1 wherein the time series data and the other time series data are from different sources.

5. The system of claim 1 wherein the similarity metric comprises a Euclidean distance based similarity metric.

6. The system of claim 1 wherein the instructions to compute comprise instructions to shift in time.

7. The system of claim 1 wherein the instructions to compute comprise instructions to filter.

8. The system of claim 1 comprising instructions to control a field operation with respect to the borehole based at least in part on the analysis of the similarity metric.

9. The system of claim 8 wherein the field operation comprises a drilling operation, a completions operation, a fracturing operation, an injection operation or a production operation.

10. The system of claim 1 wherein the time series data comprise surface condition data, downhole condition data or surface condition data and downhole condition data.

11. A method comprising:
receiving time series data from a first source associated with an operation for a borehole;
receiving time series data from a second source associated with an operation for the borehole;
computing a similarity metric based at least in part on a portion of the time series data from the first source and based at least in part on a portion of the time series data from the second source, wherein the similarity metric comprises a statistic, and wherein the statistic comprises one or both of a box plot statistic and a histogram plot statistic; and
matching at least a portion of the time series data from the first source to at least a portion of the time series data from the second source based at least in part on the similarity metric.

12. The method of claim 11 wherein the operation comprises a drilling operation.

13. The method of claim 12 wherein the matching comprises associating data.

14. The method of claim 12 comprising receiving time series data from a third source.

15. The method of claim 12 wherein at least one of the sources comprises a database.

16. The method of claim 15 wherein the database comprises a plurality of sets of time series data.

17. One or more computer-readable media that comprise processor-executable instructions wherein the instructions comprise instructions executable to instruct a computing device to:
receive time series data associated with a borehole;
compute a similarity metric for at least a portion of the time series data with respect to other time series data for the borehole, wherein the similarity metric comprises a statistic, and wherein the statistic comprises one or both of a box plot statistic and a histogram plot statistic; and
match at least a portion of the time series data to at least a portion of the other time series data based at least in part on the similarity metric.

18. The one or more computer-readable media of claim 17 comprising instructions executable to instruct the computing device to associate the matched data.
