Federated Identity Management is considered a promising approach to facilitate secure resource sharing between collaborating partners. A structured survey has been carried out in order to document the benefits of adopting such systems from a user and business perspective, and also to get an indication on how Integrated Operations in the oil and gas industry can benefit from identity federations. This has resulted in a set of benefit categories grouping existing claims from researchers. The literature indicates that adoption of Federated Identity Management in Integrated Operation seems like a good idea, however, there are several challenges that need to be solved.
