The probability of a certain well being a dry hole is 0.38, with dry hole cost of $485M. There is a 0.35 probability that the well will be successful with small reserves, in which case the NPV is expected to be $540M. If the well is successful with large reserves, the NPV is expected to be $1,100M. The decision is to drill or not drill. What is the value of perfect information in this situation, in $M? Enter a numerical value only. Your answer must be correct to within +/- 2 SM
