South Korea's SK Engineering & Construction said on Sunday that it had signed deals worth $1.9 billion with Saudi Aramco for the state oil giant's project to build the kingdom's largest gas plant Wasit.     

In late January, Aramco awarded deals to two South Korean firms, SK E&C and Samsung Engineering , but did not give a value for the deals.      

Later, industry sources told Reuters that three contracts SK E&C won were worth around $1.9 billion won.

SK added in a statement that the construction period would be within 38 months, ending in 2014. - Reuters
