I want to know the answer to the following question:
The Prelude field was estimated to contain how many cubic feet of natural gas reserves?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: yes
