As I understand it enhanced recovery though injection of things like CO2 or soapy water mixtures is very difficult and expensive for offshore rigs compared to onshore rigs.
Other than that they should be pretty much the same in terms of ammount of oil which can be recovered in the primary phase of the cycle.

I've read that it is because of the larger initial investment required. They design the projects to pay off the large initial fixed costs quickly but as a result they also have a fast decline rate. I don't know if I believe that. Certainly an oil province that is in deep water can't afford the stripper wells to squeeze out the last remaining barrels but the production profiles from the UKCS don't look like the individual fields themselves are declining precipitously.

Where in Scotland do you live?
i live in linlithgow - birthplace of mary queen of scots! i am only about 10 miles from the huge grangemouth refinery and on cloudy nights the whole sky is light up with the fires from the flare off. my house was built in the 1960's i think and originally had a coal fire, so i suppose it would be feasible to rip out the gas one and start using coal again - this also heats the water i think. i can see a lot of people doing that, its not going to be good for the air quality anyway! Up here the peat's very good, and burns for ages. I live in the Glen Lyon/Loch Tay/Loch Tummel area. I suppose the nearest well known place is Pitlochry, Aberfeldy is very close and Killin isn't far.

Quote: New Energy Minister Malcolm Wicks is hoping for a temporary three-year pause in the UK's declining oil production before the country becomes a net importer by around 2010. source: http://www.irna.ir/en/news/view/menu-23 ... 142651.htmI thought the UK was already importing oil? and then Quote: Last autumn it emerged that the UK had become a net importer of oil for the first time in 13 years. source:http://www.breakingnews.ie/2005/06/14/story207101.html
I mean what the f*** is going on, can't people even get the facts straight about their own consumption and whether or not we are importing oil?

I don't know what Malcolm Wicks is on about - I certainly didn't think it was possible to halt the decline for three years. I just don't understand how he can say that as oil extraction falls 300,000 barrels per day.

We were for a couple of months whilst maintenance was going on in the north sea.
We are not yet a net importer of oil. We still have a surplus of around 250,000 barrels per day.
Its a funny old system , despite being self sufficient (for the moment) we still export one third of our oil and the rest comes in from Norway and Algeria.
God knows why!

PB, CLV and other friends, I'm confused. Please enlighten me.
This 17% stat scared me.
What is happening?
If Gordon Brown is crying for statistical transparency for SA, shouldn't we have some at home? I notice there hasn't been an outcry in the papers about this. The idea that we might "hope" for a pause in the decline seems beyond ludicrous to me, but I'm not an energy minister 
Ferk, what do they have to do, have their brains banged out with a half-brick (e.g. Brian Wilson) to get the job?

My understanding is that its because production was ramped up so fast to counteract the oil crisis in the 70s
I don't think the onshore/offshore ultimate recovery is geologically bounded, just cost constrained.
