Argus has conducted an analysis of the Ghawar field in Saudi Arabia, which is in the early stages of waterflood, to determine the long-term impact of continuous EOR monitoring on the field.  We can project an increase in value of the Ghawar field at current ME price ($62/barrel) of between $230 billion and $370 billion.   

This amount does not include the additional value to Aramco of instrumenting the field for continuous cross-well monitoring.
