Rembrandt,

Thanks for all your efforts producing your Oilwatch Monthly report including all 129 charts!

A significant part of world liquids production is natural gas plant liquids using the EIA data source.

I would have thought that world NGLs would have been increasing given new projects from Saudi Arabia and Qatar. Instead world production is struggling to be above 8 mbd as shown below.

Saudi Arabia's NGL production has been falling from 1.44 mbd in 2007 to 1.43 mbd in 2008 to 1.31 mbd YTD Feb 2009. OPEC NGL has also fallen from 3.09 mbd in 2008 to 2.95 mbd YTD Feb 2009.

Saudi Arabia stated in its 2008 Annual Review, page 26, that the Hawiyah NGL plant started in second half of 2008 with capacity of 0.31 mbd NGL. The Khursaniyah gas plant is scheduled for completion in mid 2009 with capacity 0.28 mbd NGL.

Given new NGL capacity startups from Saudi Arabia and Qatar don't you think that OPEC NGL production would have increased? Alternatively, do you think that OPEC's lower crude oil production has forced associated NGL production down?
