NEW ORLEANS — BP said its capped-off well appeared to be holding steady Friday morning, almost midway into a tense waiting period in which engineers watched the pressure gauges for signs of a leak.
Results monitored from control rooms on ships at sea and hundreds of miles (kilometers) away at the company's US headquarters in Houston showed the oil staying inside the cap, rather than escaping through any undiscovered breaches, BP PLC vice president Kent Wells said on a conference call.
Four underwater robots scoured the sea floor but had also found no signs of new leaks.
President Barack Obama said Friday the progress was good news, but cautioned an anxious public not to "get too far ahead of ourselves." Obama said the cap was still being tested and there was still an "enormous clean up job" and need to ensure quick compensation for Gulf residents and businesses.
