This paper reviews the status of the gas-to-liquids (GTL) industry - including currentcommercial plants, announced projects and the technologies that are likely to be implemented in thesefuture projects. Today, only 35,000 B/D of GTL products (0.1% of market) are manufactured fromcommercial gas-based plants. Advances in technology have lowered the cost of plants to the point whereGTL plants can be profitable at crude oil prices of $16/B. The advanced stage of development of severalproposed GTL projects and attractive integrated economics, for both the gas field and plant, show thatGTL can be a significant altative for monetizing natural gas in the 21st century. GTL technologiesincludes more than Fischer-Tropsch technology and extends to other liquid fuels, especially in the oxygenatefamily (methanol, dimethyl ether, etc.).
