The Cheshire Grin in Kazakhstan

Talks under way between Kazakhstan and Big Oil are about much more than the nation's unhappiness with the work on the world's largest oilfield discovery of the last three decades.

It's about the future of oil. And what is it?

Despite their unprecedented profits, the Big Oil companies are on the decline, and in our lifetime -- except for those that manage to reinvent themselves -- will largely go the way of former industrial behemoths like United States Rubber, Goodyear and Bethlehem Steel.

Petro-states like Kazakhstan and Russia, meanwhile, are demanding and obtaining more control over their own fields, and increasingly marginalizing the once-omnipotent oil majors. In just two decades or a bit longer, they will be the world's big, self-contained providers of energy, and companies like BP, Shell and Exxon Mobil will either be transformed into something else, or be far smaller and mousier. They will be employees -- contractors -- for Kazakhstan, Azerbaijan, Russia, Nigeria and so on.

Already, the petro-states control between 80 percent and 90 percent of the world's oil reserves; the clock is ticking for the companies, based on reserves booked long ago, something that Wall Street will recognize at some point too.

The talks in Kazakhstan make it plain that at least Exxon -- long the most far-sighted of the companies -- understands this shift. The discussions are on the supergiant Kashagan oilfield, which is at least five years behind schedule for first oil and well over two-times over budget.

As partial compensation to irate Kazakhstan, the companies (Exxon, Shell, France's Total, Italy's ENI, ConocoPhillips and others) yesterday agreed to grant the state a larger share of the field. It's clear that Kazakhstan wants an equal share with the bigger companies, and since no dollar figures were mentioned there is still the question of whether it's willing to pay market price -- or anything at all -- for that increased stake.

In this gentlemanly form of back-alley extortion, Exxon had the gumption to insist of the man wielding the knife the equivalent of train fare home so as to live another day. Kazakhstan could have this increase, Exxon said -- but only if the contract were extended beyond its current expiry in 2041.

Kazakhstan so far has refused (it's not clear, for instance, if Exxon -- as brazen as any petro-state -- offered any money extension), but the demand is brilliant.

If such an extension is granted for, say, a decade or longer, Exxon and its partners would be on the road to extending their lives just that little bit.

There has seemed to be a Cheshire grin on some of the Kazakh and Russian oil officials in recent months.
