investing the 300 mill surplus in a bank

this does sound like a bargain at the moment.

I dont know how accurate or valid my assumptions are .. so I'd like to get a response and opinions from others.

Here's my quick rough and ready maths ...
Let's say AED invests the $300 mill cash surplus in an interest bearing bank account at 8% interest .. that's a $24 mill / annum profit just there.

Even in the worst case a production rate of only 10,000 barrels/day from the field .. and so 4,000 net barrels /day to AED(40%) ..
- it should still bring a revenue of about $150 mill/year and a profit in excess of $35 mill /annum net to AED .. based on a margin of $25/barrel.

So worst case should bring a profit of about $59 mill/annum net to AED.

the upside is if production rate can get to the notional 30,000 barrels/day rate.. in which case the profit will be about $130 mill/annum net to AED .. based on the $25/barrel margin.
