The price of oil has collapsed again.

And now the oil market is looking at a future that is "unprecedented."

In a note to clients this week, analysts at Goldman Sachs took a look at the market and the supply glut that has been blamed for the collapse in oil prices over the last year.

And as Goldman sees it, quite simply, the rules of the market have changed. "The market structure of the New Oil Order is unprecedented," the firm writes, adding that the balance of power between the market's largest and smallest companies has changed.

In the past, large integrated oil companies — like BP and Exxon Mobil — and state-owned oil companies have owned the more efficient, low-cost production while smaller oil companies faced higher barriers to entry. In the past, drilling oil necessarily required huge investments in platforms and equipment; massive balance sheets or state backing were virtually required to get into the market.

But with lower-cost fracking technology, this has changed.

And oil majors have noticed.

In a note to clients this week, analysts at Credit Suisse noted that ConocoPhillips and Total have both said the cost of production for US shale will fall 30%, and that 80% of shale oil produced will make financial sense to produce with prices below $60 a barrel at the end of this year.

The oil-futures market projects oil prices will bounce back to near $70 a barrel. The price of West Texas Intermediate crude oil finished the week below $44 a barrel.

Credit Suisse also notes that, despite the massive drop in the US oil rig count, production has remained steady.

Meanwhile, large oil companies or countries that depend on oil revenue to meet spending commitments have continued pumping oil because they still need to bring in that revenue, almost regardless of price.

This is part of why we've seen OPEC, the 12-member oil cartel led by Saudi Arabia, maintain its daily production target twice during the sharp downturn.

In its note, Credit Suisse argued that Saudi Arabia, seen as the de facto leader of OPEC, is working to get oil prices low enough such that further US shale investment is halted.

"It is, of course, very hard to know what price Saudi Arabia is targeting, but its behaviour is suggesting to us that this point has not yet been reached," the firm wrote. Credit Suisse added that while Saudi Arabia is expected to be running a 20% deficit in 2015, the kingdom is likely to be able to afford a "price war" for the foreseeable future.

Writing for The Telegraph earlier this week, Ambrose Evans-Pritchard cited analysts at Bank of America who said OPEC is "effectively dissolved."

And so on top of what seems like what's been a to-date ineffective policy from OPEC to oversupply the oil market and push out more marginal producers, oil traders are still betting that the price of oil will rise.

Credit Suisse also notes that bear markets in oil prices last between 11 and 28 years, while bull markets typically last less than 10.

Taking the long view, then, on the price of oil doesn't paint a rosy picture for the commodity.

And amid a broad rout across the commodity complex, the structure of the oil market has changed and almost everything seems to be working against it.
