A crj-200 experienced a loss of oil pressure in the right engine on descent for landing. Because the aircraft had been dispatched with an inoperative APU and all other engine indications were normal the flight crew elected to operate the engine at idle until landing to ensure the availability of electrical power should the remaining engine generator fail.

Narrative:
Descending through 17;000 ft the master warning alerted the captain (pilot monitoring) and first officer (pilot flying) to the fact the right engine oil pressure indicated zero. At that time; the captain assigned both the operation of the radios and the flying of the aircraft to the first officer. The captain then referenced the QRH while taking into consideration that the APU was MEL'ed; and our proximity to our destination.the right engine was at or near flight idle and remained at idle for the duration of the flight. All right engine readouts; except oil pressure; remained in the normal range until after the aircraft landed. All indications on the left engine indicated normal. We jointly decided continuing with the QRH procedure of shutting down the right engine was not the best course of action considering the APU was inoperative and therefore could not provide back up electrical power; that the aircraft was set up to begin the approach to the runway and that the right engine was capable of producing limited thrust. In the best interest of the safety of the passengers and crew; the QRH was discontinued.the captain notified ATC of the right engine oil problem and that we were not declaring an emergency. Minutes later; we landed safely utilizing the brakes and reverse thrust on the left engine only. The right engine was shut down immediately upon exiting the runway. Passengers were deplaned at the gate. The captain contacted maintenance control.the first officer performed a post flight inspection and observed no abnormalities. Later we restarted the right engine was restarted at the gate with outstation maintenance present. All engine indications indicated a normal start; except oil pressure indicated zero. The engine was shutdown when it became apparent oil pressure was not returning.
