3. The cost of drilling a natural gas well is $250,000. 10% of the revenue from the sale of natural gas from this particular well constitutes operating expenses. If found, natural gas from a highly productive well will amount to 260,000 cubic feet per day. However, the probability of locating such a productive well is nearly 10%. a) If natural gas sells for 8$ per thousand cubic feet, what is the E (PW) of profit to the owner/operator of this well? The life of the well is 10 years and MARR is 15% per year. (15 points) b) Repeat Part (a) when the life of the well is seven years. (15 points)
