Input: Consider Input: Passage: On 20 May 2011, Royal Dutch Shell's final investment decision for the world's first floating liquefied natural gas (FLNG) facility was finalized following the discovery of the remote offshore Prelude field—located off Australia's northwestern coast and estimated to contain about 3 trillion cubic feet of natural gas equivalent reserves—in 2007. FLNG technology is based on liquefied natural gas (LNG) developments that were pioneered in the mid-20th century and facilitates the exploitation of untapped natural gas reserves located in remote areas, often too small to extract any other way. Question: The Prelude field was estimated to contain how many cubic feet of natural gas reserves?


Output: 3 trillion
