This second system supplements the lower marine riser package (LMRP) cap containment system, which remains in operation. The new system is connected directly to the BOP and carries oil and gas through a manifold and hoses—originally deployed for the top kill procedure—to the Q4000 vessel on the surface. The Q4000 uses a specialized clean-burning system to flare oil and gas captured by this second system.
Oil and gas collected from the BOP reached the Q4000 at approximately 1:00 am CDT (7.00 am BST) on 16 June. Operations continue to stabilize and optimize the performance of the second containment system.
For the last 12 hours on 15 June (noon to midnight), approximately 4,830 barrels of oil were collected and 14.6 million cubic feet of natural gas were flared. On 15 June, a total of approximately 10,440 barrels of oil were collected and 25.1 million cubic feet of natural gas were flared. Oil collection volumes were lower on 15 June due to a temporary shutdown resulting from a direct lightening strike on the Enterprise.
Total oil collected since the LMRP Cap containment system was implemented is approximately 160,400 barrels.
The US FRTG estimates that the flow from the well is now ranging between 35,000 to 60,000 barrels per day. (Earlier post.)
