On Monday, a spokesman for the firm said that after an explosion that sunk a Transocean Ltd. (RIG) drilling rig last week, BP PLC is taking up quite a lot of choices for closing or containing an oil leak of around 1,000 barrels a day in the Gulf of Mexico.

According to the spokesman BP is still making an effort to close the oil well at the ocean floor, using distantly operated subsea robots, though, for anonymous reasons, this technique has so far been failed.

Also, BP is seeking to organize a dome without delay, over the leaking pipes to capture the oil as it leaks out, even though the technology is intended for much low water than the 1,522-meter-deep well.

The spokesman said that if attempts to close the well at the ocean floor persist to fail, the first of two rigs will land on Monday, at the site of the leak ,to drill a relief well that could halt the flow of oil from the seabed. Although, the approach could take about two to three months, he added.

"Given the current conditions and the massive size of our response, we are confident in our ability to tackle this spill offshore," said BP Chief Executive, Tony Hayward, who has flown to the U. S. to supervise the operation.
