Narrative:

At 3;000 ft MSL the right engine noise changed from normal high pitch to lower pitch. Flight crew discussed noise and possible causes. [We were] cleared to 7;000 ft. Climb initiated at 7000 ft oil pressure dropped from 87 psi to 69 psi lower but still well in green arc. [We were] cleared to FL190. Climb initiated at 17;000 ft smell of oil in cockpit; air source selector set to left engine. Through FL183; a compressor stall on right side. Right engine is shutdown. [We] asked ATC for direct ZZZ. ATC asks if we want to declare emergency. We declare emergency and turn towards ZZZ. Engine secured. Descent and approach [were] uneventful. Smell of oil is cockpit goes away; normal landing. Cessna mechanics believe number two bearing in right engine is to blame. They are currently performing engine inspection.
