Hi Euan,

Thnaks for that suggestion, I will break Ghawar into sub fields for forecasting in my model.

In your base model forecast you show both North and South Ain Dar having no forecast production in 2013. Do you think that North and South Ain Dar will be abandoned completely or will they continue producing some kind of hydrocarbons (oil, NGL, gas)?

My guess is that they may start a massive program of tertiary recovery using gas injection. So in reality production may go on for decades at a greatly reduced rate. They can also have a program of infill drilling - the well spacings here are still enormous. And they can opt for infield water injection - i.e. injecting water into swept zones to improve sweep efficiency. So my forecast is really just for the final stage of dry oil production with associated wet area production.
