Oil again sprayed under the Gulf of Mexico

Oil and gas continued to escape from the broken bottom of the Gulf of Mexico, a few days after the BP group put a new cap into the well.

AP said, after the cover has a volume of 75 tons placed in a broken oil well, BP engineers track the well through underwater camera system. They also constantly updated the pressure and seismic indicators to see if the lid prevents oil from escaping. Results showed that a small amount of oil and gas started leaking from the evening of July 18. However, Admiral Thad Allen, the special envoy in charge of the government's oil spill, said the phenomenon was not worrisome.

The engineers also discovered another crack on the seabed last weekend. The crack was about 3 km away from the well, but Allen thought it was irrelevant to the well. Until now, people often witnessed the scene of oil and gas erupting from cracks in the Gulf of Mexico.

The US government and BP have not agreed on the use of lids. BP wanted to keep the lid on the well until the robot dug into a "rescue" well next to it. Meanwhile, Allen initially wanted BP to suck oil through the cover and then onto the ships above the water to reduce the pressure inside the well. If the pressure is too great, an explosion can occur. If you follow Allen's idea, several million liters of oil will be lost during the ship's arrival - a scenario BP wants to avoid.

But Allen's opinion changed yesterday. He said if there was no major threat, he would not support opening the lid to suck oil.

Both BP and the US government are trying to figure out why the pressure in the well is lower than the experts' calculations. Allen assumed that the oil bag under the well was shrinking, or there was an undiscovered crack under the well.
