NEW ORLEANS — An oil spill that has been quietly leaking millions of barrels into the Gulf of Mexico has gone unplugged for so long that it now verges on becoming one of the worst offshore disasters in U.S. history.
Between 300 and 700 barrels of oil per day have been spewing from a site 12 miles off the Louisiana coast since 2004, when an oil-production platform owned by Taylor Energy sank in a mudslide triggered by Hurricane Ivan. Many of the wells have not been capped, and federal officials estimate that the spill could continue through this century. With no fix in sight, the Taylor offshore spill is threatening to overtake BP’s Deepwater Horizon disaster as the largest ever.
