The news was even worse for Diamond Offshore, with unconfirmed reports spreading through the media that Diamond's Ocean Saratoga rig in the Gulf of Mexico was leaking.

reported that a pilot who flew over the Diamond rig saw a plume of oil. Diamond referred calls to Taylor Energy, which leased the rig from Diamond, but there was no immediate comment on the pilot's report from the energy company.

Late on Tuesday afternoon, Taylor Energy issued a press release saying that the report was wrong. In fact, the leak in the well for which Taylor has been using the Diamond Offshore Saratoga rig dates back to Hurricane Ivan in 2004.

Taylor Energy said its ongoing well intervention program using the Diamond Ocean Saratoga started when the platform was toppled by a subsurface mud slide triggered by storm surges with 100 foot waves for 16-18 second periods during the 2004 hurricane.

Three subsurface containment domes and six well interventions have been part of the containment effort for years, Taylor Energy said.

Taylor Energy said the photos quoted in the press as proof of the oil spill were photos of boats involved in regularly scheduled subsea containment system drainage, and that tanks that were identified in press reports as chemical dispersants were, in fact, oil-storage tanks.

Diamond Offshore shares had been among the biggest losers in the market in the first half of Tuesday's trading, but by the end of the market, Diamond Offshore closed down less than 4% -- though on four times its average volume of shares traded.
