Narrative:

We were at 27;000 ft in cruise when the right engine oil pressure began to fluctuate. As we began to watch it the pressure started to slowly go down. The first officer (first officer) was flying and flew the aircraft the entire time to landing. I ran the QRH for engine oil fluctuations then descend to 21;000 ft and then 17;000 ft the pressure continued to go down which lead me to the shutdown the engine because the pressure now was below 25 psi as I followed the QRH. [We advised ATC] and we proceeded to ZZZ into an uneventful single engine landing.
