BP Plc is continuing its probe for a section of its drill pipe it has to remove before replacing the blowout preventer from top of the Macondo well which is five thousand feet below the surface of the Gulf of Mexico.  

Both the preventer and the drill pipe which are made up of valves for ceasing the sudden rise in pressure will be used for investigating the disastrous incident that claimed eleven lives in the world’s biggest accident that happened in the Gulf of Mexico where the BP well had exploded.   

The Deepwater Horizon rig sank out of a blast when the preventer failed to cease a burst of gas from escaping the seafloor on the twentieth of April.  

Bp has plans to replace the Maconado preventer with one unlatched preventer from an idled oil well of the spill site as per the website information given by the company which is based in London.  

To procure the government permit for switching out the preventers, BP has to submit timeline and operational plans, as stated by Thad Allen, the National Incident Commander yesterday.  

According to statement made by Allen in an email the procedure would help to recognize and preserve the forensic value and evidences of the blown out preventer stack. According to Allen by the procedure further release of oil can be removed or captured through the measures taken in the process.  

According to BP one thousand barrels of oil are still there trapped in the Macondo well. The final plugging will be deferred by three weeks if the drill pipe is recovered and the preventer is replaced as said by Allen on the nineteenth of August.  

The “bottom kill”  is the process in which mud and cement will be pumped from the bottom of the well and that won’t take place before the sixth of September. BP planned to carry out that operation around fifteenth of August.
