Abstract: The present invention provides a method and apparatus for remotely analyzing and affirmatively notifying appropriate personnel of problems and events associated with an oil recovery system—comprising hundreds of oil rigs over a vast geographic area. The results of selected Health Checks, which are run on each oilrig, are reported to a central server. The central server populates a data base for the oil recovery system, displays a red/yellow/green color coded electronic notification and status for an entire oil recovery system and affirmatively alerts appropriate personnel of actions required to address events associated with an oilrig in an oil recovery system. The diagnostics run at each oilrig are configurable at the individual rig. The present invention provides a dynamic oilrig status reporting protocol that enables population and display of a tree node structure representing an entire oil recovery system status on a single screen at a top level.
