Due to the threat of large swells, several oil rigs along the Texas coastline were evacuated as a precautionary measure. Workers from Chevron Corporation and Anadarko Petroleum were evacuated from offshore platforms while those working for ConocoPhillips and ExxonMobil remained on site. The Louisiana Offshore Oil Port was also shut down on November 9 as a result of Ida's passage. As a result of the decreased oil production, the price of oil rose more than $1 to $78 per barrel. Among the rigs that were damaged was the Transocean Marianas which was drilling the Macondo well. That vessel would be replaced on the Macondo Well by the Deepwater Horizon, which caused the Deepwater Horizon oil spill in 2010.
