Narrative:

While at cruise altitude of FL350 at approximately XA45Z, the crew observed the 'right engine oil pressure' light begin to flicker. Engine indications (N1, N2, egt) appeared normal but the #2 oil pressure was indicating low (near 80 psi with occasional drop into the red zone), oil quantity was at zero. Flight control was advised and with their concurrence initiated the engine oil pressure checklist, and after being advised of vibrations from the cabin initiated the engine fire or severe damage or separation checklist. We discussed the option of a divert to phx but with the concurrence of flight control agreed the nearest suitable airport was las vegas, nv. The flight proceeded to las as an emergency aircraft, where an uneventful flaps 20 degree landing was made. After clearing the runway, we had the crash fire rescue equipment check the condition of the aircraft, after which we taxied to the gate uneventfully.

Title: A B757 CREW, IN CRUISE AT FL350, EXPERIENCED LOW OIL PRESSURE AND QUANTITY ON THE #2 ENG, REQUIRING SHUTDOWN.

Narrative: WHILE AT CRUISE ALT OF FL350 AT APPROX XA45Z, THE CREW OBSERVED THE 'R ENG OIL PRESSURE' LIGHT BEGIN TO FLICKER. ENG INDICATIONS (N1, N2, EGT) APPEARED NORMAL BUT THE #2 OIL PRESSURE WAS INDICATING LOW (NEAR 80 PSI WITH OCCASIONAL DROP INTO THE RED ZONE), OIL QUANTITY WAS AT ZERO. FLT CTL WAS ADVISED AND WITH THEIR CONCURRENCE INITIATED THE ENG OIL PRESSURE CHKLIST, AND AFTER BEING ADVISED OF VIBRATIONS FROM THE CABIN INITIATED THE ENG FIRE OR SEVERE DAMAGE OR SEPARATION CHKLIST. WE DISCUSSED THE OPTION OF A DIVERT TO PHX BUT WITH THE CONCURRENCE OF FLT CTL AGREED THE NEAREST SUITABLE ARPT WAS LAS VEGAS, NV. THE FLT PROCEEDED TO LAS AS AN EMER ACFT, WHERE AN UNEVENTFUL FLAPS 20 DEG LNDG WAS MADE. AFTER CLRING THE RWY, WE HAD THE CFR CHK THE CONDITION OF THE ACFT, AFTER WHICH WE TAXIED TO THE GATE UNEVENTFULLY.
