Norway Investigates Substantial Leak At BP's Ula Oil Field

"OSLO - The Norwegian Petroleum Safety Authority, or PSA, said Tuesday it is investigating a substantial oil leak at the BP PLC operated Ula oil field in the North Sea.

Production is still suspended after the leak, which occured Sept. 12. No people were injured, but the PSA "considers the incident to have had a substantial potential," it said in a statement.

"We have launched an internal investigation of the incident," said BP spokesman Olav Fjellsaa, who confirmed that both oil and gas had leaked from the Ula platform, but said it was too early to estimate how much.

The leak arose in the separator module on Ula's production platform, the PSA said. The platform was automatically shut down, and all personnel was evacuated to Ula's drilling platform. The Ula field consists of three conventional steel platforms for production, drilling and quarters, linked by bridges.

The Ula field produced 317,500 barrels of oil in July, or about 10,200 barrels per day, according to the Norwegian Petroleum Directorate.

Ula is an oil field in the southern part of the North Sea, at a sea depth of 70 meters. The main reservoir is 3,345 meters below the seabed.

The field's peak production was 52.4 million barrels in 1993, or 143,600 barrels per day on average. In 2011, production had fallen to 4.8 million barrels, or 13,200 barrels per day on average.

The oil from the field is transported by pipeline via Ekofisk to Teesside.

Operator BP Norge AS has an 80% stake in the Ula field, and partner Dong E&P Norge AS has a 20% stake."

Quote: A spokesman for BP in Norway said the company had launched its own investigation but that it was too early to determine how much oil and gas had leaked out.

"We have set up a team to investigate the origin of the leak and prevent a recurrence of this kind of incident in the future," Jan Erik Geirmo told AFP.

"We will not restart the platform until the investigation is completed," he added.

He said a thin layer of oil could be seen "for a brief moment" on the water before it disappeared.

Sure it disappeared. bored.gif Magic Norwegian oil.

A lot of commercial fishing in that area so that's definitely a concern. Hopefully they won't corexit the hell out of the North Sea.

What's their (everyone's) problem with not putting extra safeguards in place? gaah.gif

I don't know what safeguards are required in that region. Understand this is a production platform and not a drilling rig like Macondo incident. I would have thought there would be auto shutoffs like here in USA. My friend working for Oceaneering that inspects platforms and pipelines gets fussed at all the time for "thumping" platforms with the boat which automatically shuts down production at the wellhead.

Good, that's the auto. shutdown technology (drilltronics) I would expect to be there, but from the article I just skimmed through, they seem to have to continually update the technology. Yeah, two shutoff valves would do the trick...is that too much to ask for?

Depends on where the leak is located. Seems this one was at the oil and gas separator which aren't exactly high tech. If it was both oil and gas then must have been on the incoming line, pre-separation. There should be pressure sensors to monitor any incoming and outgoing pressures. Also along production lines to indicate any leaks. Damnit....

You make it sound all so simple and easy to manage...and shut off! Damnit...

It's supposed to be that easy. The oil and gas separator is nothing more than a large cylinder where the gas/oil mix enters say 75% up cylinder, oil falls to bottom and flows out the oil line and there is a valve much like a toilet float valve working in reverse where the more oil that flows in and level rises the more open the valve to allow a certain level and line out of the top is just gas. Simple

There has to be pressure sensors to monitor and auto shut off valves...
