HOUSTON (Reuters) - BP Plc said on Friday it has completed a pressure test on its blown-out Gulf of Mexico well and those results are under review by government scientists and the British oil company.
A recommendation on how to proceed is expected to go to the U.S. government, BP said in a brief news release.
BP may not need a nearly completed relief well to drill into the bottom of the ruptured Gulf of Mexico well if the pressure test shows that cement poured in from the top last week killed the leak, the top official overseeing the government's spill response said on Thursday.
The test could indicate BP already cleared the last hurdle to terminate the source of the world's worst offshore oil spill, retired Coast Guard Admiral Thad Allen told reporters at a briefing on Thursday.
No oil has leaked into the Gulf of Mexico since July 15, when BP plugged the top of the well with cement.
Shares of BP traded in London rose 1.2 percent while the stock rose nearly 1 percent in New York trading.
