BP today is all set to go ahead in testing the bigger cap that would be placed in the leaking well, and this would be the biggest step by BP to completly seal off the oil leak. The step to go ahead with the test began late evening on Wednesday, but then a leak was discovered and process was stopped until the leak is not fixed. Earlier the government was not sure of the process, as it feared that it would make matters worse.

Admiral Thad Allan, stated that there is an urgent need to go ahead with the procedure, but he has also warned that there should be no such mistake that cannot be resolved. On the other hand, BP feels that the new valve will help in stopping the leakage. The test would go this way, as the officials screw on the valve choke, they would test the integrity of the new device by testing the seismic, acoustic and temperature changes in the surrounding areas of the well.

After the test would be successfully completed, the federal government would refer the data collected and would take the steps of permanently shutting the leak by relief wells and would also shut down the well for some time, due to an oncoming hurricane. During the test BP would monitor the whole process, if there is high pressure then, oil is being contained successfully, but if there is low pressure then there is a leak somewhere else.
