Minister of Oil Dr. Ali Al-Omair Sunday termed as"excellent" commercial relations between Kuwait Petroleum Corporation (KPC) andShell, with the multi-billion-dinar Liquefied Natural Gas (LNG) contract as the culmination of this relation.Al-Omair, also Minister of State for National Assembly Affairs, made the remarks on the sidelines of a ceremony to sign the six-year KD 12 billion (USD 42.7 billion) LNGcontract.He said the contract would be harmless to environment because LNG was the leastharmful energy source on environment.Kuwait, he added, would also save KD hundreds of millions because it would not beburning oil but rather replace it with LNG. Diesel and crude oil consist of high concentration of sulphur which harms theenvironment, said Al-Omair, in addition to the consequent costly maintenance ofpower stations.
