Weather forecasts advance apprehension may drive the discharge aground at the weekend.
Eleven bodies died back an access destroyed the Deepwater Horizon conduct rig on 20 April.
Owned and operated by Transocean, the rig had been alive on account of BP at a able-bodied armpit 48 afar (77km) off Louisiana.
Thousands of barrels of oil acquire been blubbering circadian into the sea from the well's burst riser pipe, about a mile beneath the surface.
BP is application underwater robots in its latest attack to stop the leak, which involves jamming a tube into the aqueduct to carry oil to a tanker on the surface.
'Trust but verify'
Mr Obama was speaking afterwards affair his chiffonier and added administering admiral in the White House.
"For too long, for a decade or more, there has been a cosy accord amid the oil companies and the federal bureau [the Minerals Management Service, MMS] that permits them to drill," he said in the Rose Garden.
"It seems as if permits were too generally issued based on little added than assurances of assurance from the oil companies. That cannot and will not appear anymore. To borrow an old phrase, we will assurance but we will verify."
Interior Secretary Ken Salazar, Mr Obama added, was alive on a "top-to-bottom reform" of the MMS.
It was appear beforehand that the MMS administration which permits oil and gas conduct and collects royalties would be afar from the MMS administration in allegation of analytical the assurance of oil rigs and platforms and administration the law.

New estimates
The discharge is assertive to become the affliction ecology adversity in US history.
Some scientists acquire amorphous to casting agnosticism on official estimates of the bulk of oil flow, adage the broadly again bulk of 5,000 barrels of oil per day badly understates the amount.
