Narrative:
We were at FL370 in cruise. The first indication noticed by the crew was the low oil pressure alert for the #2 engine. The oil pressure was rolling back through the yellow and below 13 psi as I was pulling the QRH. We followed the QRH procedure for low oil pressure to engine shutdown. We declared an emergency with ATC and requested FL200 after consulting FMC engine out altitude of FL226. We received clearance for direct [the departure airport] and to descend to FL200. After the turn was executed; the captain transferred controls to me and alerted dispatch (via ACARS) and briefed flight attendants and passengers. The captain returned and received clearance to the IAF for the ILS. We briefed approach and arrival; analyzed the non-normal configuration landing chart; single-engine go-around procedures; confirmed arff would be available and standing by; completed QRH through approach and landing and executed a single engine overweight landing.
