Rembrandt - this is great work and extremely useful. I'll use this all the time. You maybe want to stick an author reference on every chart - light grey water mark. I for one will cut and use these charts on a regular basis.

A couple of observations. Despite Buzzard coming on at near capacity, the trend of falling peaks and troughs in the UK has not been broken. We have had a lot of focus recently on Saudi Arabia and I'm beginning to wonder what is the state of the fields in UAE - they just had a couple of super giants from what I can recall - Bab and Zacum? Azerbaijan - pumping 800,000 bpd up from 300,000. The BTC pipleine has capacity of 1 million bpd - so it looks like this is not yet at capacity - some more supply growth to come there.

Is it possible to identify top ten NGL producers?

Its a lot of work to produce this monthly - so I wonder if quarterly may suffice - but showing monthly data.

Regarding UAE, around 200,000 b/d of additions from 2006 to 2007 and 300,000 from 2007 to 2008, coming from NEB Phase I (al-Dabb-iya, Shanayel, Rumaitha), Bu Hasa, Lower Zakum - Umm Shaif, OGD 3 & AGD 3 and Huwaila.
So far these increases in the UAE do not have any effect, production has been flat since the end of 2005. In this case I would say they voluntarily dropped production to drive oil prices higher.
>Is it possible to identify top ten NGL producers?
Yes, but not on a monthly basis since the monthly data per country is very bad. There is good quarterly data available in the IEA's quarterly OECD statistics bulletin. This however also includes lease condensates and maybe even some synthetic liquids (canada) from what I can spot in the numbers.
Top producers (4rd quarter 2006) for NGL are as follows according to the IEA:
USA - 1,759,000 b/d
Saudi Arabia 1,510,000 b/d
Algeria 810,000 b/d

Canada 699,000 b/d
United Arabic Emirates 579,000 b/d
Norway 547,000 b/d
Qatar 410,000 b/d
Mexico 400,000 b/d
Iran 391,000 b/d
Russia 316,000 b/d

Ill keep it on a monthly basis for now, most work goes in the changes throughout the entire database, or adding new parts such as import-export data.
