Shamma said one of the sticking points was that Shell wanted more guarantees for the amount of associated gas
it would be able to utilise from the three southern fields -- Rumaila, Zubair and West Qurna Phase One -- covered by the deal.
This can treat and processe associated gas
from the Karatchok, Suwaidiyah and Rumailan oilfields.
Bourland notes that around 60 per cent of Saudi Arabia's gas output is associated gas
produced alongside crude oil.
The Energy Ministry's Natural Resources Department owns the associated gas
lying in reservoirs operated by firms other than TPAO.
It has the capacity to treat up to 80,000 CM/day of associated gas
and can extract small quantities of LPG and condensates.
NGL-1 processes associated gas
produced from Dukhan into 1,350 t/d of ethane-rich gas; 1,284 t/d of propane; 851 t/d of butane; and 588 t/d of NGL.
These now produce 145 MCF/d and their output should reach more than 1,000 MCF/d by 2016, in addition to associated gas
being used extensively (see gmt23KwtFieldsJun6-11).
