$this->bbcode_second_pass_quote('ROCKMAN', 'D')C - Not silly at all. Models are OK. But they are also like masturbating: nothing wrong with it as long as you don't start thinking it's the real thing. LOL.
I don't make fun of anyone's prediction until I see if they are correct or not. If correct I admit I thought they were right the whole time. If wrong then I'll blast them. That's the only way to not look foolish in the prediction game IMHO.
Rockman,
I frankly love the criticism that you and others offer, these charts are less predictions than scenarios, if x, y, and z change in the ways I have laid out, the chart may be close to reality.
I have noticed that when I ask for suggestions about how realistic the assumptions are you don't bite, but maybe you can help me with the following question:
"What annual discount rate do you use in your NPV calculations when evaluating a prospective project 10%, 15%, 25%?"
Also for wells like the EFS would you assume the wells last for 5, 10, or 20 years when doing an NPV exercise?
When the sweet spots have been drilled up fully, how quickly would you expect the EUR of new wells to fall at an annual rate, 10 %, 25%? If one assumes that well completion rate remains unchanged, so that if we were at 2100 wells per year and continued at that rate until we ran out of space in the play (economics are ignored) how fast would one expect the EUR of new wells to decrease?
My guess is 12.4 % does that seem low, high or about right?
