Abstract

Examples of techniques for anonymizing data are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes receiving, by a processing device, raw data from a wellbore operation. The raw data can be associated with depths. The method further includes anonymizing, by the processing device, the raw data to convert the raw data to anonymized data. One or more techniques can be implemented to anonymize the data, such as shuffling the raw data, normalizing the raw data, and/or non-dimensionalizing the raw data. The method further includes analyzing, by the processing device, the anonymized data. The method further includes performing an action at the wellbore operation based at least in part on the analysis of the anonymized data.

First claim

What is claimed is:

1. A computer-implemented method for anonymizing data, the method comprising:
receiving, by a processing device, raw data from a wellbore operation;
anonymizing, by the processing device, the raw data to convert the raw data to anonymized data by normalizing the raw data to ensure that a numeric range of the raw data are comparable;
analyzing, by the processing device, the anonymized data; and
performing an action at the wellbore operation based at least in part on the analysis of the anonymized data.

2. The computer-implemented method of claim 1 , wherein the numeric range of the anonymized data is [0,1].

3. The computer-implemented method of claim 1 , wherein the numeric range of the anonymized data is [−1,1].

4. The computer-implemented method of claim 1 , further comprising:
generating, by the processing device, a key during the anonymizing, the key being configured to enable the anonymized data to be deanonymized.

5. The computer-implemented method of claim 4 , further comprising:
deanonymizing, by the processing device, the anonymous data to generate results data by applying the key to the anonymous data to generate the results data.

6. The computer-implemented method of claim 1 , wherein the analyzing comprises performing a lithology classification for the wellbore operation based at least in part on the anonymized data.

7. The computer-implemented method of claim 1 , wherein anonymizing the raw data is performed in a confidential environment.

8. A computer-implemented method for data anonymization, the method comprising:
receiving, by a processing device, raw data from a wellbore operation;
anonymizing, by the processing device, the raw data to convert the raw data to anonymized data by non-dimensionalizing the raw data;
analyzing, by the processing device, the anonymized data; and
performing an action at the wellbore operation based at least in part on the analysis of the anonymized data.

9. The computer-implemented method of claim 8 , wherein raw data comprise pore pressure data, and wherein anonymizing the data by non-dimensionalizing the data comprises dividing the pore pressure data by vertical stress data.

10. The computer-implemented method of claim 8 , wherein raw data comprise maximum horizontal stress data, and wherein anonymizing the data by non-dimensionalizing the data comprises dividing the maximum horizontal stress data by vertical stress data.

11. The computer-implemented method of claim 9 , wherein raw data comprise minimum horizontal stress data, and wherein anonymizing the data by non-dimensionalizing the data comprises dividing the minimum horizontal stress data by vertical stress data.

12. The computer-implemented method of claim 8 , wherein raw data comprise unconfined compressive stress data, and wherein anonymizing the data by non-dimensionalizing the data comprises dividing the unconfined compressive stress data by vertical stress data.

13. The computer-implemented method of claim 8 , wherein the analyzing comprises performing a lithology classification for the wellbore operation based at least in part on the anonymized data.

14. The computer-implemented method of claim 9 , wherein the analyzing comprises performing a predicting fracture initiation pressure for the wellbore operation based at least in part on the anonymized data.

15. The computer-implemented method of claim 8 , wherein anonymizing the raw data is performed in a confidential environment.

16. A system comprising:
a memory comprising computer readable instructions; and
a processing device for executing the computer readable instructions for performing a method for anonymizing data, the method comprising:
receiving, by a processing device, raw data from a wellbore operation, wherein the raw data are associated with depths;
anonymizing, by the processing device, the raw data to convert the raw data to anonymized data by normalizing the raw data to ensure that a numeric range of the raw data are comparable and by non-dimensionalizing the data to remove units from the raw data;
analyzing, by the processing device, the anonymized data; and
performing an action at the wellbore operation based at least in part on the analysis of the anonymized data.

17. The system of claim 16 , wherein the anonymized data comprises first anonymized data, and wherein analyzing the first anonymized data comprises combining the first anonymized data with second anonymized data.

18. The system of claim 17 , wherein the first anonymized data is associated with a first wellbore operation and the second anonymized data is associated with a second wellbore operation.

19. The system of claim 18 , wherein the first anonymized data is anonymized in a first confidential environment, and the second anonymized data is anonymized in a second confidential environment.
