Gas processing plants in Saudi Aramco process both the associated gas received from oil wells and the
non-associated gas (Khuff gas) received from gas wells. Uthmaniyah Gas Plant (UGP) of Southern
Area Gas Operations in Saudi Aramco is one of the largest gas processing plants in the world. Both the
associated and the non-associated gas streams are crucial to meet the growing domestic gas demand and
as well as of great significance for future mode of operation. The associated gas and the non associated
gas are transported form their respective wells to the gas processing plant through buried cross country
pipelines.
