We departed with 3 passengers. At approximately 500 feet AGL a (R) LO OIL PRESS annunciator illuminated and the (R) oil pressure gauge indicted zero. At a safe altitude; power was reduced on the right engine; and the checklist was call for. Oil pressure did not respond to throttle movement and indicated 0 PSI. Therefore; we shut down the engine IAW (in accordance with) the emergency/abnormal checklist; secured it; and [advised ATC]. We returned to [the departure airport] and landed without incident. We elected to land at 19;300 LBS; 600 LBS over max landing weight.
Cessna Citation Excel Captain reported a complete loss of oil pressure in one engine; resulting in an engine shutdown; and a return to the departure airport.
