NZ Oil & Gas (NZO)

[temptation]

5.2m tonnes @ 7.5 barrels per tonne = 39 million barrels of oil (equivalent to 75% of current Tui estimate)

above link on crown minerals gives some very interesting detail about kupe

Reply to an e-mail requesting more frequent posted information on Tui production Chris Roberts (Public Affairs Manager)
"What we are able to do is once or twice a week update our website with the approximate running production total."

After thanking him I have asked when this is likely to begin. Hopefully soon.

Cheers

some data from crown minerals re kupe 4 south and kupe 5 south - had to cull it a bit

their website is really good - just wish we understood all the terms.

Fish,

Based on NZOG 2007 annual report – page 48 (Energy Values)

1,000 standard cubic ft of gas yields approximately 1 gigajoule of heat
1 petajoule (PJ) = 1,000,000 gigajoules (GJ) = approximately 1 billion cubic feet (bcf)


200 bcf = 200,000,000 GJ

1 barrel = 5,800 standard cubic ft of gas = ~5.8 gigajoule of heat (GJ)

200 bcf = ~34.5 million barrels of oil

Wish I'm right.

Cheers

Addition


1 PJ = ~1 bcf

1 PJ of Natural Gas = 172,000 barrels of oil equivalent

200 bcf = 172,000 barrels x 200 = ~34.4 million barrels of oil (same as the above)


Cheers

200 bcf = ~34.5 million barrels of oil

Wish I'm right.

Sounds encouraging, allright. But let's remember it's gas (well, probably gas & condensate, maybe oil yet to be found!!) and they haven't actually got 30m bbl of oil, just its energy equivalent.

Exciting times

[Chalice]

The weather has been pretty rough on a number of days lately. That will interfere with both production and offloading. It is winter. They are operating offshore in the Tasman.

"Modification of the FPSO to include an innovative swivel production turret, allowing the vessel to swivel for currents and weather whilst maintaining production output"

Be interesting to know the timing of this modification as it should improve output in a rough part of the world.

Good spotting - Surely that must be wrong.Tui averaged 42,500 every day for 335 days. It seems wierd that it can be as low as 25,000 for the six days of July.

Anyone else got thoughts?

Wasnt the weather not too good a few days ago? 2 days of shut down might explain it. I dont think the workers will be operating in 100k plus winds

That modification was made prior to delivery. It allows production to continue as the ship changes direction with the wind. It does not magically allow production, or offloading, to take place in strong winds and high seas.
