The Ichthys LNG is ranked among the most significant oil and gas projects in the world. Located about 136 miles (220 kilometers) offshore Western Australia, it lies in an average water depth of 820 feet (250 meters). The Ichthys field is estimated to contain more than 12 trillion cubic feet of gas and 500 million barrels of condensate.
