The book has very basic information on LNG and its meaning in the International market. It would not be so bad if the author would stick to the same units all through the book. Instead, he uses starts by using Bcf/d (Billion Cubic Feet per day), then he changes to Bcm/y (Billion Cubic Meters per year), and by page 48 he talks about MMt/y (Million Metric Tons per year); all this makes the book very confusing. Either use Cubic Meters, or stick with Cubic Feet, but stay with one convention. Carrying my calculator around town made the reading experience extremely annoying!
