Big Oil spends more, pumps fewer barrels

By Alex Lawler - Analysis

LONDON (Reuters) - The world's three largest fully publicly traded oil firms are investing billions of dollars more this year and the extra spending has yet to result in higher production.

Exxon Mobil Corp. (XOM.N), Royal Dutch Shell Plc (RDSa.L) and BP Plc (BP.L) posted falling second-quarter output, even though they plan up to a total of $61 billion in 2007 capital spending, up 5.5 percent from 2006.

"We're in a transition for the supermajors where they are spending an awful lot to reinvigorate their portfolios," said Jason Kenney, European oil analyst at ING in Edinburgh. "It takes time."

The drop in supply reflects declining output from fields in mature oil regions like the North Sea, violence by militants in Nigeria that has cut output for some companies and slow access to big sources of new reserves.

Oil firms get some production from countries in the Organization of the Petroleum Exporting Countries but top exporter Saudi Arabia keeps its oilfields off-limits to foreign investors.

OPEC's members, whose oil industries are run by national oil companies, sit on three-quarters of the world's proven reserves and 10 of the 12 members pump crude at agreed levels to bolster prices.

Besides disruptions in Nigeria, which have trimmed output for Shell and other companies, Venezuela and Russia are grabbing more cash and control from firms that work their oil and gas fields.

LESS EASY OIL

Resources are increasingly located where extraction is technically harder, such as beneath seas that ice over in winter off Russia's Sakhalin Island, or in politically volatile regions like the Middle East.

"Access to easy oil and easy gas...there's less access and less of those hydrocarbons around," said Shell Chief Executive Jeroen van der Veer when the company reported earnings last week.

"The new supplies will come out of more complex projects -- far away, very cold, different political regimes. They're usually large-scale projects, with risks."

Shell last week posted a 2 percent drop in oil and gas output to 3.178 million barrels of oil equivalent (boepd) in the second quarter.

Exxon, the only one of the three to raise output last year, had a 1 percent fall in production to 4.12 million boepd and BP's supply fell by 5 percent to 3.8 million boepd.

Exxon said supply fell because of declines at mature oil fields, OPEC production cuts and lower European demand for natural gas.

Shell lowered its sights for full-year production, saying it would be at the lower end of a previously given range of 3.3 million to 3.5 million boepd this year.
