Minister of Oil Dr. Ali Al-Omair Sunday termed as "excellent" commercial relations between Kuwait Petroleum Corporation (KPC) and Shell, 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) LNG contract. He said the contract would be harmless to environment because LNG was the least harmful energy source on environment. Kuwait, he added, would also save KD hundreds of millions because it would not be burning oil but rather replace it with LNG. Diesel and crude oil consist of high concentration of sulphur which harms the environment, said Al-Omair, in addition to the consequent costly maintenance of power stations.
