BP install new cap on oil leak

British Petroleum (BP) has successfully installed a new sealing cap on the leaking oil well in Gulf of Mexico.



A company official said it hoped the new cap will stop the leak and capture all the oil.



BP warned the cap system had never been deployed at such depths and said its efficiency and ability to contain the oil and gas cannot be assured.



The company also said that the two relief wells being drilled remain the only way to permanently seal the leak.



That process is due to be completed by mid-August.
