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, 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 shuffling the raw data and removing the association with the depths;
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 analyzing comprises performing a lithology classification for the wellbore operation based at least in part on the anonymized data.

3. The computer-implemented method of claim 2 , wherein the lithology classification is a binary lithology classification.

4. The computer-implemented method of claim 2 , wherein the lithology classification is a multi-class lithology classification.

5. The computer-implemented method of claim 1 , wherein the raw data comprise gamma ray data, density data, and resistivity data.

6. The computer-implemented method of claim 1 , wherein anonymizing the raw data further comprises removing header information from the raw data.

7. The computer-implemented method of claim 1 , wherein the raw data comprises stress data, and wherein anonymizing the raw data further comprises converting the stress data to equivalent gradients.

8. The computer-implemented method of claim 1 , further comprising:
deanonymizing, by the processing device, the anonymous data to generate results data.

9. The computer-implemented method of claim 8 , wherein deanonymizing the anonymous data to generate the result data comprises applying a key to the anonymous data to generate the results data.

10. The computer-implemented method of claim 1 , wherein performing the action at the wellbore operation comprises performing at least one of a drilling action, a completion action, and a production action.

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

12. 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 the processing device, first raw data from a first wellbore operation, wherein the first raw data are associated with first depths;
receiving, by the processing device, second raw data from a second wellbore operation, wherein the second raw data are associated with second depths;
anonymizing, by the processing device, the first raw data to convert the first raw data to first anonymized data by shuffling the first raw data and removing the association with the first depths;
anonymizing, by the processing device, the second raw data to convert the second raw data to second anonymized data by shuffling the second raw data and removing the association with the second depths;
aggregating, by the processing device, the first anonymized data and the second anonymized data to generate aggregate anonymized data;
analyzing, by the processing device, the aggregate anonymized data; and
performing an action at the first wellbore operation or the second wellbore operation based at least in part on the analysis of the aggregate anonymized data.

13. The system of claim 12 , the method further comprising:
deanonymizing, by the processing device, the first anonymous data from the aggregate anonymized data to generate first results data by applying a first key to the anonymous data to generate the first results data, wherein the second anonymous data remains anonymous.

14. The system of claim 12 , the method further comprising:
deanonymizing, by the processing device, the second anonymous data from the aggregate anonymized data to generate second results data by applying a second key to the anonymous data to generate the second results data, wherein the first anonymous data remains anonymous.

15. The system of claim 12 , wherein anonymizing the first raw data is performed in a first confidential environment, and wherein anonymizing the second raw data is performed in a second confidential environment.
