ANWR was stripped out of the Energy Bill
It's in the Budget Bill (I said that didn't I, if I said Energy Bill, my bad), it was put there to get past the sure filibuster if it remained in the Energy Bill.
ANWR was stripped out of the Energy bill repeatedly, but it IS in the Budget Resolution which cannot be "filibustered". (I use filibustered in quotations because I'm a proceedural purist and what the Dems have been doing lately is not a filibuster in my sense of the word.)
