HOUSTON/WASHINGTON (Reuters) - BP Plc's stricken Gulf of Mexico oil well showed no signs of leaking on Friday, but officials intensified oversight after a critical test showed pressure barely rising in the capped gusher.
BP began pressure tests on the well after choking it off on Thursday for the first time since the April 20 rig explosion that triggered the leak. Underwater robots scanned the sea floor for signs the undersea well was damaged.
