RE:RE:RE:RE:RE:RE:RE:Look at the big picture You are correct in that offshore has more capital invested, which can justify using more expensive equipment (sometimes more efficient, powerful, and technologically advanced - but not always the case). Offshore wells are designed to extract more oil faster, but this is also is required to make the economics of offshore work because of the time value of money (a bbl of oil selling at $60 today is worth a lot more than that same bbl selling for $60 10 years from now), the capital investment needs to be payed off, and the quicker the better.
Interestingly enough, generally onshore plays have a much higher rate of return and a quicker pay off period, but the problem becomes scalability and NPV moving the needle of large companies' earnings over their entire portfolio. Honestly, economics associated with any and all oil and gas developments are very complex and multifaceted, and I don't think you ever really stop learning. But it is because of these complexities that it is so hard to evaluate RECO and it's potential (could be the moon or could be rock bottom) unless you are working for the company. And this is why you'll see a bunch of unsubstantiated values for future SP... it's people's speculation who know nothing about the economics of upstream O&G, and can't back up their guesses with any semblance of reason. They call rational people bashers, but I'm not, I just try to be rational and admit that I might as well throw darts at a dart board to guess on an SP.
