Systems and methods for diagnosing production problems in oil field operations are provided. A first video monitor displays an oil field diagnosis process flow chart that includes selectable objects such as Review Well Test Differences, Review Sliders, Review Bad Actors, and Perform Steam Flood Performance Check. Each selectable object is associated with one or more incompatible domain-specific software applications. One or more of the selectable objects are selected and one or more additional video monitors display reports extracted by a middle-ware software code segment layer from the associated domain-specific software applications. Oil wells having production problems are listed and problem oil wells are displayed on an oil field map. Any commonalities among the displayed problem oil wells indicative of a common cause of the production problems are visually identified. Work is scheduled in the associated domain-specific software applications sufficient to remedy the common cause.

Systems and methods for diagnosing production problems in oil field operations

The invention includes a method for determining a steam injection schedule for a set of subsurface formation subsurface regions of an oil field, the method including the steps of determining a thermal maturity for each subsurface region of the set; calculating a latent heat target for each subsurface region according to the determined thermal maturity therefore; calculating a steam injection target for each subsurface region according to the calculated latent heat target therefore; determining the availability of steam for injection to the subsurface regions; and calculating a steam injection schedule for each subsurface region according to the determined steam availability and calculated steam injection targets for all subsurface regions of the set.
