Yup. That's the way it happens. As prices go up and it becomes harder to find and more difficult to extract the methods have changed to match the new challenges ... and the money available. Its been that way for over 1000 years now. They used to find it just sittin' there on top of the ground, then just under the surface with gas at high pressure, then deeper, then shallow, but no pressure and a little gas, then a little oil, but no gas, then associated with water, then a lot of water, then tight sands, then offshore, then tight sands that needed fracturing, then deep offshore, horizontal drilling, then way up there in Alaska, then not even anywhere close, now sometimes, but a great discovery today is only for 60 days of US supply, then . Problem is that now we're just barely staying ahead of the game, if you talk to some, and definitely losing the race, if you talk to others. It is good to see that there's still a little something you can hope for, even with nothing but bad land to your name though.
