All that’s left

As always very relevant insights by Mr Rubin.It's now claimed by some the oils spill from this disaster can be up to some 5.000 bpd at the moment. Then and as the emergency lock 1,900 meters below the surface securing that no oil is coming out from the well is not working the only possible means of stopping this disaster is by placing a huge metal cylinder over the well. This is a tested method that has worked earlier. Only problem is that newer before on these debts only at shallow waters. Imagine doing this type of rescue work at the debts. First issue is that the cap will not be at hand within four weeks. That’s then four weeks of oil spill equivalent of up to even 5.000 bpd. Then in this contexts it's hard to argue that Tars sand should even be remotely as environmental unfriendly as of shore deep sea oil drilling. In fact in the tars sand you have oil polluted dirt and sand. By using e.g. in-situ methods the oil is the removed from the ground and what is left is an improved environment than will be able to heal itself after some years. That's for sure harder to say relevant to this massive oil spill in the Gulf.

America’s dream of greater energy independence is rapidly turning into an ecological nightmare. Instead of filling empty gas tanks, BP’s Deepwater Horizon well miles offshore is oozing thousands of barrels a day of oil, already covering an area over 1,900 square miles in the food-rich waters of the Gulf of Mexico. With no way of shutting off the valve, which is now buried 1,900 meters below the sea, a $2 billion seafood industry is threatened, not to mention the billions more in damage to coastal real estate values and the potential devastation to wetlands and the wildlife they contain if the growing slick washes ashore.

Most forms of unconventional oil and gas (including, by the way, shale gas) are invariably very hard on the environment. Although tar sands production draws most of the world’s criticism, we are quickly discovering that deep-water wells and the pressure surges they engender run the risk of wreaking even greater ecological and environmental devastation.

And the deeper that technology allows us to drill miles below the ocean floor, the greater the risk that we will see more and more of these disasters. If this week has shown us the pressure surge of wells a mile below the ocean floor, what are the prospects of our standing up to those we’ll encounter in newly discovered Gulf of Mexico fields like BP’s Tiber one, six miles below the ocean floor?

Of course, devastating leaks haven’t been the only thing to thwart America’s efforts to boost its oil production in the Gulf. Five years ago, Hurricane Katrina and the other Category 3 to 5 storms that hit the region devastated its oil industry. Instead of doubling production levels, as once confidently forecast by the US Department of Energy, production got hammered. In fact, it’s only very recently returned to pre-Katrina levels, only now to face an entirely different setback.

Why is this so potentially devastating to America’s oil future? The Gulf of Mexico was the only area of the country where there was any reasonable hope of expanding domestic supply. Production in the lower 48 states peaked in the early 1970s, as predicted by the American geophysicist King Hubbert back in 1956. And despite the enthusiasm of the “drill, baby, drill” lobby to do more in Alaska, that state’s oil production has been depleting even faster than in the rest of the country. As a result, a country that once produced ten million barrels a day is now barely able to produce half that amount.

If you’re wondering why we’re risking catastrophic environmental consequences by drilling wells miles below the ocean floor, the answer is simple enough. It’s the same answer to the question of why we’re pouring billions of dollars into the tar sands.

It’s all that’s left.
