Abstract: Systems and methods for managing large oil field operations are provided. A oil field map is displayed on a monitor. The oil field map includes oil well objects, oil field facility objects, surface work crew objects, subsurface work crew objects, safety zones objects, and work equipment rig objects associated with at least one work crew object and having a geographic locater device for tracking its location, each of the objects include a date attribute and a location attribute. The oil field map is customizable by date and has a date selector tool. At least two surface or sub-surface work crew objects are scheduled via a domain-specific software application from which the surface or sub-surface work crew object was extracted. The scheduling of the surface or sub-surface work crew objects is repeated until all surface and sub-surface work crews are scheduled for a date range of interest.
