The US government has authorised 24 more hours of tests in the oil spill area in the Gulf of Mexico after experts detected seepage from the surrounding seabed.

Monday's move comes a day after the administration ordered BP to submit a plan for reopening its recently capped blown-out oil well to allow oil to flow into the ocean again after engineers detected seepage on the ocean floor near the well.

Thad Allen, the retired coast guard admiral overseeing the government's response to the spill, told Bob Dudley, the BP chief managing director, in a letter on Sunday to report on a "detected seep" and other "anomalies" near the Gulf of Mexico oil.

"Given the current observations from the test, including the detected seep a distance from the well and undetermined anomalies at the well head, monitoring of the seabed is of paramount importance during the test period.

"I direct you to provide me a written procedure for opening the choke valve as quickly as possible without damaging the well should hydrocarbon seepage near the well head be confirmed," he said.

More than three days since BP started using a new, tighter fitting cap to stop the oil from gushing out of the well 1.6km below the surface, the British energy giant said the cap was holding.

"The fear is that at some point the pressure inside the that cap will blow a large hole in it, or damage it irretrievably, and at all events, that has to be avoided," Richard Miller, former geologist of BP told Al Jazeera.

"If you loose control of that well-head, then I am afraid you have nothing left upon which you can attach any further containment device," Miller said.

Earlier on Sunday, BP officials had expressed hope that the test of the cap which began Thursday could continue until a relief well being drilled reaches the damaged well and heavy drilling mud and cement is used to seal it more permanently.

Doug Suttles, BP's chief operating officer, told reporters that reopening the well would release oil into the Gulf for up to three days even though capture vessels were standing by on the surface to begin processing oil within hours.

"We're hopeful that if the encouraging signs continue that we'll be able to continue the integrity test all the way to the point that we get the well killed," he told reporters before Allen issued his statement.

"Clearly we don't want to reanimate flow into the Gulf if we don't have to."

Before the cap was placed, nearly 10 million litres of oil was spewing into the Gulf every day for nearly three months since BP's rig exploded and sank in late April, according to the US government's worst case projections.

BP was able to siphon some of that oil to ships on the surface but was not able to shut off the flow until fitting the cap on Thursday.

Meanwhile, BP said Monday the cost of dealing with the spill reached nearly $4bn.

The company said it has paid $207m to settle individual claims for damages from the spill along the southern coast of the United States.

To date, almost 116,000 claims have been submitted and more than 67,500 payments have been made.
