Update on Gulf of Mexico Oil Spill - 25 June


BP today provided an update on developments in the response to the MC252 oil well incident in the Gulf of Mexico.

Subsea Source Control and Containment
Two systems continue to collect oil and gas flowing from the Deepwater Horizonís failed blow-out preventer (BOP) and transport them to vessels on the surface.

The lower marine riser package (LMRP) containment cap, installed on June 3, takes oil and gas to the Discoverer Enterprise where oil is collected and gas flared. The second system, which began operations on June 16, takes oil and gas to the Q4000 vessel on the surface where both oil and gas are flared.

Oil and gas collection through the LMRP cap containment system was suspended for approximately 10 hours on June 23 following an unexpected release of seawater from the Discoverer Enterprise. Capture of oil and gas through the system connected to the Q4000 continued throughout the day.

On June 23, a total of approximately 16,830 barrels of oil were collected or flared by the two systems and 36.7 million cubic feet of gas were flared. Specifically, the LMRP containment system connected to the Discoverer Enterprise collected 8,300 barrels of oil, and the Q4000 flared an additional 8,530 barrels of oil. To date, the total volume of oil recovered or flared by the containment systems is approximately 364,500 barrels.

Information on the volumes of oil and gas that are captured or flared is updated twice daily on BPís website, The LMRP containment cap and Q4000 systems never before have been deployed at these depths and conditions, and their efficiency and ability to contain or flare the oil and gas cannot be assured.

Preparations continue for the next step in containment operations. Preparation of the first floating riser containment system that will be connected to the Helix Producer vessel remains on schedule. It is currently anticipated that this system will be available to begin first operations at the end of June or in early July. Plans also are being developed for additional containment capacity and flexibility. These projects are currently anticipated to begin operations around mid-July.

Work on the first relief well, which started May 2, continues. The well reached a depth of 16,275 feet on June 23 before the drillstring was removed from the well to carry out the first írangingí run using wireline. During the ranging run, the MC252 well was successfully detected. Subsequent ranging runs will be needed to more precisely locate the well. Drilling and ranging operations will continue over the next few weeks towards the target intercept depth of approximately 18,000 feet, when íkillí operations are expected to begin. The second relief well, which started May 16, is drilling ahead at a measured depth of 10,500 feet. Both wells are still estimated to take approximately three months to complete from commencement of drilling.

Surface Spill Response and Containment
Work continues to collect and disperse oil that has reached the surface of the sea, to protect the shoreline of the Gulf of Mexico, and to collect and clean up any oil that has reached shore.

Approximately 37,000 personnel, more than 4,500 vessels and some 100 aircraft are now engaged in the response effort.

Operations to skim oil from the surface of the water now have recovered, in total, approximately 610,000 barrels (25.6 million gallons) of oily liquid. In addition, a total of 275 controlled burns have been carried out to date, removing an estimated 239,000 barrels of oil from the seaís surface.

The total length of containment boom deployed as part of efforts to prevent oil from reaching the coast is now almost 2.8 million feet (530 miles), and about 4.2 million feet (800 miles) of sorbent boom also has been deployed.

Additional information
To date, almost 74,000 claims have been filed and more than 39,000 payments have been made, totalling almost $126 million.

The cost of the response to date amounts to approximately $2.35 billion, including the cost of the spill response, containment, relief well drilling, grants to the Gulf states, claims paid, and federal costs. On June 16, BP announced an agreed package of measures, including the creation of a $20 billion fund to satisfy certain obligations arising from the oil and gas spill. It is too early to quantify other potential costs and liabilities associated with the incident.
