To date, the total volume of oil collected or flared by the containment systems is approximately 585,400 barrels.
Besides, work on the first relief well, which started May 2, continues, the company said. The well reached a depth of 17,725 feet on July 4 and a sixth ‘ranging’ run was completed. The second relief well, which started May 16, has now reached a measured depth of 13,871 feet. Both wells are still estimated to take approximately three months to complete from commencement of drilling.
Approximately 44,500 personnel, more than 6,563 vessels and some 113 aircraft are now engaged in the response effort.
Operations to skim oil from the surface of the water have recovered, in total, approximately 673,497 barrels (23.5 million gallons) of oily liquid. In addition, a total of 275 controlled burns have been carried out to date, removing an estimated 238,000 barrels of oil from the sea’s surface.
The cost of the response to date amounts to approximately $3.12 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 escrow account 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, BP said.
