(A)Use @RISK distributions to generate the three random variables and derive a distribution for the amount of reserves.What is the amount we can expect to recover from this field?
(B)The production output is a product of three very different types of input distributions.What does the output distribution look like? What are the implications of the shape of this distribution?
(C)What is the standard deviation of the recoverable reserves? What are the 5th and 95th percentiles of this distribution? What does this imply about the uncertainty in estimating the amount of recoverable reserves?
(D)Suppose you think oil price is normally distributed with a mean of $65 per barrel and a standard deviation of $10.How much revenue do you expect the field produce (ignore discounting)?
