Narrative:

I happened to notice that the left engine oil quantity was indicating zero. We then saw that the oil pressure was in the green but falling slowly. The first officer was given flying duties and ATC. I completed the procedures for oil pressure low and also the precautionary engine shutdown. We declared an emergency and diverted to mem. We then notified our dispatcher who then made arrangements for arrival in mem. Next we told our flight attendants what was going on and told them they had 15-20 mins to prepare for a normal landing in mem. I then informed the passenger that we had lost oil in 1 engine and were operating it at 'reduced power,' and that we would be landing in mem. We had airport rescue fire facility standing by as a precaution. We made a normal and uneventful landing, albeit on 1 engine. As a precaution we had a fire truck follow us to the gate. I feel that our training served us well and that dividing up the workload between the first officer and myself were key to keeping the situation manageable. The first officer did an excellent job, and the flight attendants were very professional and calm, which helped keep the passenger at ease.
