Timor Sea oil slick may now be lapping Indonesian shores

The West Timor Care Foundation has sent the Australian Greens a video claiming the 10-week Montara oil spill is now lapping the south shores of Timor. The five minute video shows oil slicks and dead fish in local fishing grounds (though when I entered the location coordinates shown in the video it came up in Philippine waters). The government doubts the slick has approached the Indonesian coastline and has announced no compensation measures as yet.

The Montara spill is a major catastrophic event happening out of reach of Australian news cameras. From 21 August to 3 November a possible 140,000 barrels of light crude oil, gas and condensate leaked into the sea. Owners PTTEP claimed the well leaked 400 barrels of oil a day but couldn’t confirm this estimate. The Australian government said the maximum flow could be 2000 barrels a day. After four unsuccessful attempts, it was eventually plugged when heavy mud was injected into the underground leaking well. The spill was complicated by a major fire on the rig two days earlier.

The vast amount of oil leaked into the sea continues to cause havoc. West and East Timor authorities have asked Australia to take urgent actions to stop the impact on their island. The governor of East Nusa Tenggara (Indonesian West Timor) said Australia must take “immediate measures” to halt the spill. East Timorese President Jose Ramos Horta says the slick is impacting fishermen’s livelihood and has requested compensation from Australia.

The Montara wellhead on the West Atlas rig is in Australian waters 250km northwest of the Truscott air base in Western Australia’s Kimberley region and 250km from the south Timor coastline. The rig is owned by Thai based oil company PTT Exploration and Production Public Company (commonly known as PTTEP) and run by its Australian subsidiary PTTEP Australasia Company Limited (PTTEP AA).

The problem started when a concrete plug 2.6km below the ocean floor cracked open leaking sweet crude oil, gas and condensate into the Timor Sea. The cause has not yet been made public however an unnamed industry insider told WAtoday.com PTTEP knows the reason. The source was working for PTTEP near the West Atlas rig on the day the leak occurred. He said one of six wells they were drilling began to leak because the company took corners by not plugging the well securely when they did not expect oil flow.

The company went into panic mode as desperate efforts failed to plug the leak. After three failed attempts, they invited Texan well control company Boots & Coots to review their operation. Local industry companies Woodside, Inpex, Vermillion, AGR Petroleum Services and Apache also became involved on a “without prejudice” basis (to avoid liability) as the reputation of the Australian oil drilling industry plummeted. The rig caught fire on the fourth attempt and took three days to put out. The leak was plugged by steering a drill through rock 2.6km below the seabed to a 25cm diameter pipe.

Resource Minister Martin Ferguson announced an inquiry headed by former senior public servant David Borthwick. The terms of reference are to report on the causes, the adequacy of the regulatory regime in response, the performance of those carrying out the response, environmental impacts and PTTEP’s role. Borthwick will have six months to investigate. The Australian Marine Conservation Society said the oil slick will leave a legacy for decades and called on the government to impose heavy sanctions and penalties.

Greens Senator Rachel Siewert is concerned the consequential impacts to Indonesia and East Timor may be outside Borthwick’s terms of reference. Minister Ferguson claims the spill is over 200kms from the Indonesian coastline. But Siewart called on the government to investigate the Timorese reports of oil contamination for links to the Montara rig. “Australians expect that we will do the right thing by our near neighbours,” she said. “The Prime Minister needs to promise that he will ensure the company takes responsibility for impacts outside of Australian waters.”
