Abstract

An example method for validating field data associated with a field having a plurality of wellsites. The method includes obtaining a validation policy associated with the field, the validation policy including a business validity rule, a trend validity rule, and a contextual validity rule for verifying the field data based on field operation guidelines. The method further includes receiving the field data associated with the field. The method further includes, prior to storing the field data for use in a field operation, evaluating the field data using the validation policy, identifying a failure of the field data during the evaluation to comply with the validation policy, generating, using the failure, a set of invalid data that violates at least the field operation guidelines, and generating a notification of the failure. The method further includes presenting the notification of the failure and the set of invalid data.

Claims

1. A method for validating field data associated with a field having a plurality of wellsites, the method comprising:

obtaining a validation policy associated with the field, the validation policy comprising a business validity rule, a trend validity rule, and a contextual validity rule for verifying the field data based on field operation guidelines;

receiving the field data associated with the field;

prior to storing the field data for use in a field operation;

evaluating the field data using the validation policy,

during the evaluation, identifying a failure of the field data to comply with the validation policy,

generating, using the failure, a set of invalid data that violates at least the field operation guidelines, and

generating a notification of the failure; and

presenting the notification of the failure and the set of invalid data.

2. The method of claim 1, wherein:

the field data is received in a set of blank data entry fields of a data entry interface; and

the validation policy further comprising a valid data entry format, a database constraint, and a range of data values.

3. The method of claim 1, wherein:

the business validity rule specifies a type of field data required for the field operation,

the trend validity rule verifies the field data based on a pattern of current field data and historical field data, and

the field operation guidelines describe physical properties associated with the field.

4. The method of claim 1, wherein the trend validity rule verifies the field data by analyzes the correlation of variables associated with the field operation.

5. The method of claim 1, wherein the field data is received as a first field data value in a first data entry field, and wherein the validation policy automatically populates a set of data entry fields of a data entry interface based upon the selection of the first field data value.

6. The method of claim 1, wherein presenting the notification of the failure further comprises presenting a potential cause of the failure.

7. The method of claim 1 further comprising:

associating the set of invalid data with an identifier to generate flagged data; and

performing a global validation operation on the flagged data.

8. The method of claim 1, further comprising:

generating a contour map based on the evaluation, the contour map comprising selected report parameters comprising at least one of group consisting of an isorisk property, an isoloss property, an isostuck property, an isotime property, an isocost property, an isolength property, an isodeep property, an isobit property, and an isocasing property; and

presenting the contour map.

9. The method of claim 1, further comprising:

presenting recommended drilling operations based on evaluating the field data.

10. The method of claim 1, further comprising:

receiving a selection of offset wells responsive to receiving the selection of offset wells, querying a database to locate historical data associated with the selection of offset wells;

identifying best practices information from the historical data, wherein the best practices information is generated during a dynamic validation of the field data as the field data is received from a data generation source;

generating a recommendation for performing a wellsite operation, wherein the recommendation identifies selected drilling parameters; and

presenting the recommendation.

11. The method of claim 10, wherein the selection of offset wells is selected from a contour map.

12. A computer readable medium comprising instructions executable by a processor to perform a method for validating field data associated with a field having a plurality of wellsites, the instructions comprising functionality for:

receiving the field data associated with the field;

in response to receiving the field data and prior to storing the field data for use in a field operation;

performing a validation of the field data to generate a validated set of data, the validation comprising;

verifying that the field data conforms to a business validity rule associated with the field;

verifying that the field data conforms to a trend validity rule associated with the field;

verifying that the field data conforms to a contextual validity rule associated with the field; and

generating the validated set of data based on the field data conforming to the business validity rule, the trend validity rule, and the contextual validity rule;

generating a notification of the field data validation; and

presenting the notification of the field data validation and the validated set of data.

13. The computer readable medium of claim 12, the validation further comprising:

verifying that the field data is of a valid format;

verifying that the field data satisfies database constraints; and

verifying that the field data is of a valid range.

14. The computer readable medium of claim 12, wherein:

the business validity rule specifies a type of field data required for the field operation,

the trend validity rule verifies the field data based on a pattern of current field data and historical field data, and

the contextual validity rule verifies the field data based on field operation guidelines, the field operation guidelines describing physical properties associated with the field.

15. The computer readable medium of claim 12, the instructions further comprising functionality for:

generating recommended drilling operations based on the validated set of field data; and

presenting the recommended drilling operations.

16. A system for validating field data associated with a field having a plurality of wellsites, the system comprising:

a policy repository configured to provide a validation policy, the validation policy comprising a business validity rule, a trend validity rule, and a contextual validity rule;

a field data repository configured to store the field data and a set of invalid data;

a field data processing engine configured to process the field data stored in the field data repository for use in evaluating the field; and

a validation engine comprising a user interface for receiving the field data, the validation engine configured, prior to storing the field data in the field data repository, to;

evaluate the field data using the validation policy,

during the evaluation, identify a failure of the field data to comply with the validation policy,

generate, using the failure, the set of invalid data that violates at least the field operation guidelines,

generate a notification of the failure, and

present the notification of the failure and the set of invalid data.

17. The system of claim 16, wherein:

the business validity rule specifies a type of field data required for the field operation,

the trend validity rule verifies the field data based on a pattern of current field data and historical field data, and

the contextual validity rule verifies the field data based on field operation guidelines, the field operation guidelines describing physical properties associated with the field.

18. The system of claim 16, wherein the field data repository is further configured to store validated field data, best practices information, and flagged field data.

19. The system of claim 16, wherein the policy repository is further configured to store a data entry policy, the validation policy, and a data cleaning policy.

20. The system of claim 16, wherein the validation engine is further configured, prior to storing the field data in the field data repository, to present recommended drilling operations based on evaluating the field data.
