“The MC252 well appears to have reached a static condition -- a significant milestone,” the company said in a statement.
The company has stopped pumping drilling fluids into the well and is monitoring pressure inside, before deciding whether to pump more fluids down the well.
BP’s shares were down 0.6 percent, in line with the STOXX Europe 600 Oil and Gas index .SXEP at 0819 GMT.
“This would suggest that the static kill operation is looking successful,” Peter Hitchens, oil analyst at Panmure Gordon said. (Reporting by Tom Bergin; editing by Simon Jessop)
