Subsea Source Control
The MC252 well has been shut-in since July 15; there is currently no oil flowing into the Gulf. BP continues to work with the guidance and approval of the National Incident Commander and the leadership and direction of the federal government.
Following the completion of cementing operations on the MC252 well on August 5, pressure testing was performed which indicated there is an effective cement plug in the casing. BP believes the static kill and cementing procedures have been successful.
BP continues to progress the relief well operations that commenced on May 2. The well is currently at a measured depth of 17,909 feet. Progressing towards the intersect with the MC252 well will involve drilling alternating with ranging runs to confirm proximity to the well. Depending upon weather conditions, August 15th is the current estimate of the most likely date by which the first relief well will intercept the MC252 well annulus.
Operations on the second relief well, which started May 16, have been suspended at a measured depth of 15,874 feet, so as not to interfere with the completion of the first relief well.
Information on the subsea operational status is updated daily on BP’s website, www.bp.com.
Surface Spill Response
Work continues to identify and collect oil on the surface of the sea and to collect and clean up oil that has reached shore. Since July 15, no new oil has flowed into the Gulf of Mexico from the MC252 well. As a result, BP, as part of Unified Command, has conducted overflights and other reconnaissance and has found less skimmable quantities of oil over the last several days. To date, skimming operations have recovered a total of over 826,000 barrels of oily liquid and a total of 411 controlled burns have been carried out.
Approximately 30,800 personnel, more than 5,050 vessels, and dozens of aircraft are engaged in the response effort.
The cost of the response to date amounts to approximately $6.1 billion, including the cost of the spill response, containment, relief well drilling, static kill and cementing, grants to the Gulf states, claims paid, and federal costs. This includes an adjustment to cost run rates based on actual charges received. On June 16, BP announced an agreed package of measures, including the creation of a $20 billion escrow account to satisfy certain obligations arising from the oil and gas spill.
