I want to know the answer to the following question:
Prudhoe Bay is second place in production to what other oil field in the US?
All the background I'm provided with is that "Prudhoe Bay on Alaska's North Slope is still the second highest-yielding oil field in the United States, typically producing about 400,000 barrels per day (64,000 m3/d), although by early 2014 North Dakota's Bakken Formation was producing over 900,000 barrels per day (140,000 m3/d).". Is that enough to answer the question?
