The survey confirmed that no oil is leaking from the Macondo well, nor from the relief well
that ultimately intercepted and permanently sealed it.
A relief well
remains the ultimate solution to kill and permanently cement the well," said BP.
Even if we were to pump the cement from the top, we will still continue on with the relief well
and confirm that the well is dead.
BP said on Sunday that a rig that had been drilling a relief well
to plug the Gulf of Mexico oil leak was back on site and reconnecting equipment to resume work.
What we didn't want to do is be in the middle of an operation and potentially put the relief well
at some risk," Kent Wells, BP's vice-president, said.
The relief well
being drilled to halt BP's spill is a week ahead of schedule, the US official overseeing the response to the disaster said on Tuesday.
25 pence at 1507 Dubai time, pushed ahead by the good news on the relief well
front as well as by investment speculation.
The pair also said BP's runaway Macondo well, the site of the April 2010 Deepwater Horizon drilling rig explosion, likely won't stop spilling oil into the gulf until the first relief well
is completed in mid-August.
Oil gushed from Ixtoc I until a relief well
could be drilled.
The state news agency quoted unnamed experts as saying that to stifle the fire a relief well
might need to be drilled next to the flaming well to suck off the oil and gas feeding the fire.
The relief well
at the end of August is certainly the end point on this game," Robert Dudley, BP's managing director, said.
Kent Wells, BP's senior vice president of exploration and production, said on Thursday that of all the ships and rigs at the spill site, the relief well
rigs needed the most time to disconnect and move.
