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.
