Narrative:
A mechanical failure of the oil system in the #2 engine occurred in-flight and the specific cause of the failure is currently under investigation. The event was a rapid loss of oil quantity from the #2 engine. The captain and I idented the problem while inside ZZZ airspace at 7000 ft. The captain was the PNF and accomplished the appropriate checklists. An emergency was declared to ATC and a safe single engine landing was accomplished on runway 28 at ZZZ airport. Because of the lapse in time needed for the checklist and securing the aircraft for landing we did not notify the flight attendant of our situation before landing. No damages or injuries occurred; so we proceeded to the gate to deplane the passenger. The loss of oil was noticed by the decreasing oil pressure indication on the EICAS display followed by a warning message on the EICAS. Once the event was idented we accomplished the appropriate checklists which led us to shut down the #2 engine. An emergency was declared and a single engine landing was accomplished.

Title: LOSS OF OIL QUANTITY IN RIGHT ENGINE RESULTS IN E145 FLT CREW DECLARING EMERGENCY AND RETURNING TO DEP ARPT FOR AN IMMEDIATE LNDG.
Narrative: A MECHANICAL FAILURE OF THE OIL SYS IN THE #2 ENG OCCURRED INFLT AND THE SPECIFIC CAUSE OF THE FAILURE IS CURRENTLY UNDER INVESTIGATION. THE EVENT WAS A RAPID LOSS OF OIL QUANTITY FROM THE #2 ENG. THE CAPT AND I IDENTED THE PROB WHILE INSIDE ZZZ AIRSPACE AT 7000 FT. THE CAPT WAS THE PNF AND ACCOMPLISHED THE APPROPRIATE CHKLISTS. AN EMER WAS DECLARED TO ATC AND A SAFE SINGLE ENG LNDG WAS ACCOMPLISHED ON RWY 28 AT ZZZ ARPT. BECAUSE OF THE LAPSE IN TIME NEEDED FOR THE CHKLIST AND SECURING THE ACFT FOR LNDG WE DID NOT NOTIFY THE FLT ATTENDANT OF OUR SITUATION BEFORE LNDG. NO DAMAGES OR INJURIES OCCURRED; SO WE PROCEEDED TO THE GATE TO DEPLANE THE PAX. THE LOSS OF OIL WAS NOTICED BY THE DECREASING OIL PRESSURE INDICATION ON THE EICAS DISPLAY FOLLOWED BY A WARNING MESSAGE ON THE EICAS. ONCE THE EVENT WAS IDENTED WE ACCOMPLISHED THE APPROPRIATE CHKLISTS WHICH LED US TO SHUT DOWN THE #2 ENG. AN EMER WAS DECLARED AND A SINGLE ENG LNDG WAS ACCOMPLISHED.
