BP reports new pipeline leak at Lisburne oilfield in Alaska
Latest leak is likely to do nothing to mend oil giant's reputation in US after 2010 Deepwater Horizon disaster

BP reported yet another pipeline leak at its Alaskan oilfields, frustrating the oil giant's attempts to rebuild its reputation after the Gulf of Mexico oil spill. BP has said that a pipeline at its 30,000 barrel per day Lisburne field, which is currently closed for maintenance, ruptured during testing and spilled a mixture of methanol and oily water onto the tundra.
The company has a long history of oil spills at its Alaskan pipelines – accidents which have hurt its public image in the US, where around 40% of its assets are based.
The Alaska Department of Environmental Conservation said the spill occurred on Saturday and amounted to 2,100 to 4,200 gallons. A BP spokesman said the cleanup was under way and the company would determine the cause "in due course."
Lisburne, which is managed as part of the Greater Prudhoe Bay Unit, has produced no oil since 18 June, according to Alaska Oil and Gas Conservation Commission records, suggesting maintenance work requiring a prolonged shutdown. The spokesman said the field had been undergoing "its annual maintenance."
BP's blown out Macondo well caused the worst offshore oil spill in US history after the Deepwater Horizon drilling rig exploded, spewing almost 5m barrels of oil into the Gulf and putting BP's future in the US at risk.
Previous problems including leaks from corroded pipelines in Alaska and the fatal Texas City refinery blast in 2005 have already earned the company a poor reputation for safety, something analysts say it needs to address if it is to continue to grow in North America.
BP shares were down 1.089% at 454p this morning.
Production from the entire Lisburne field remains shut off while the spill is addressed, Alaska officials said. Immediate efforts are focused on containment and cleanup, said Tom DeRuyter, the state on-scene coordinator for the Department of Environmental Conservation.
The methanol-produced water mix has spread into wet tundra as well as onto a gravel pad, bringing risks to slow-growing vegetation, DeRuyter said. "You have actively growing plants and they're very susceptible to the contaminants.
