Narrative:

Level at 11;000 feet [after departure] and accelerating; the left oil press lo annunciator illuminated. I noted the oil pressure to be 35 psi at this point and decreasing rapidly. I was the pilot flying; and at this time I took the radios so captain (ca) could run the appropriate checklists. I requested return to [departure airport]. Complied with QRH oil pressure low. Step 2a says 'with oil pressure less than 35 psi and oil press lo annunciator; engine shutdown required. Refer to engine failure/shutdown procedure this section'. Complied with QRH engine flameout/shutdown/failure. Secured the left engine as oil pressure was dropping through about 10 psi. Ca notified the cabin crew with the nature of the [situation] and to prepare the cabin. He also addressed the passengers that we would be returning to [departure airport] due to mechanical issues.as the pilot flying; I got the weather and decided [on] the best suitable runway. I flew a visual approach; single engine. We ran all appropriate single engine approach and landing checklists. Emergency vehicles met us on the taxiway; where we told them we could taxi to the gate. They followed us there for safety purposes. Upon arriving at the gate; we were met by mechanics; who further informed us that a chip detector had 'blown' and we had lost all oil. QRH phraseology changes from one procedure to the next. Needs to be uniform for faster compliance.when referring to a procedure in the QRH that should be followed next; it would be helpful to have the procedure number for faster look up.
